Why Is Oxygen A Waste Product Of Photosynthesis


Why Is Oxygen A Waste Product Of Photosynthesis?

Oxygen is released by plants after photosynthesis as a waste because plants require carbon dioxide water and sunlight to synthesis glucose. … So the waste products are oxygen glucose and energy which are utilised by other living organisms.Nov 15 2017

Is oxygen the waste product of photosynthesis?

Photosynthesis uses solar energy carbon dioxide and water to produce energy-storing carbohydrates. Oxygen is generated as a waste product of photosynthesis.

Why is oxygen a waste?

Plants use a process called photosynthesis to make their own food. During photosynthesis a plant uses light water and carbon dioxide to make its own food. Oxygen is given off during photosynthesis as a waste product. This is the reaction that only plants and some algae and bacteria can do.

Where does the waste product oxygen come from in photosynthesis?

Although the hydrogen atoms from the water molecules are used in the photosynthesis reactions the oxygen molecules are released as oxygen gas (O2). (This is good news for organisms like humans and plants that use oxygen to carry out cellular respiration!) Oxygen passes out of the leaves through the stomata.

What is the waste product produced in photosynthesis?

carbon dioxide

These sugar molecules are the basis for more complex molecules made by the photosynthetic cell such as glucose. Then via respiration processes cells use oxygen and glucose to synthesize energy-rich carrier molecules such as ATP and carbon dioxide is produced as a waste product.

In which process is oxygen a waste product *?


Oxygen is a waste product of photosynthesis.

Where does the waste product of oxygen come from during photosynthesis quizlet?

The oxygen released during photosynthesis comes from the splitting of water during the light-dependent reaction. 3. Remember the electrons lost from the reaction center in photosystem II must be replaced. The splitting of water serves to replace these lost electrons.

What is oxygen depleting waste?

What is oxygen depleting waste? Explanation: Oxygen depleting waste is organic that can be decomposed by aerobic bacteria. Large populations of bacteria use up the oxygen present in the water in order to degrade these wastes. This degrades the water quality as it uses up the oxygen.

How is oxygen used in photosynthesis?

Within the plant cell the water is oxidized meaning it loses electrons while the carbon dioxide is reduced meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air and stores energy within the glucose molecules.

Do plants need oxygen for photosynthesis?

You probably know that plants generate oxygen during photosynthesis. Since it’s common knowledge that plants take in carbon dioxide and release oxygen into the atmosphere during this process it may be a surprise that plants also need oxygen to survive.

What is the role of oxygen in photosynthesis and in cellular respiration?

In photosynthesis solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. … In cellular respiration oxygen is used to break down glucose releasing chemical energy and heat in the process. Carbon dioxide and water are products of this reaction.

What would happen if oxygen were not available?

Explanation: Aerobic respiration requires oxygen. In aerobic respiration one molecule of glucose is broken down to produce 34 to 36 molecules of ATP the energy currency of the cell. If there was no oxygen available aerobic respiration would stop and organsims that rely on aerobic respiration would die.

What are the waste products of photosynthesis quizlet?

A waste product of photosynthesis is oxygen which is needed for cellular respiration in animals.

What is the gaseous waste product produced in the light reactions?

oxygen gas

The light reactions capture energy from sunlight which they change to chemical energy that is stored in molecules of NADPH and ATP. The light reactions also release oxygen gas as a waste product.

Where is oxygen gas from?

Oxygen can be produced from a number of materials using several different methods. The most common natural method is photo-synthesis in which plants use sunlight convert carbon dioxide in the air into oxygen. This offsets the respiration process in which animals convert oxygen in the air back into carbon dioxide.

Why are oxygen demanding wastes pollutants?

A second category of water pollutants is oxygen-demanding wastes wastes that can be decomposed by oxygen-requiring bacteria. When large populations of decomposing bacteria are converting these wastes it can deplete oxygen levels in the water. This causes other organisms in the water such as fish to die.

How does oxygen depletion affect the environment?

When oxygen levels in the water are depleted relatively harmless aerobic microorganisms die and anaerobic microorganisms begin to thrive. Some anaerobic microorganisms are harmful to people animals and the environment as they produce harmful toxins such as ammonia and sulfides.

What are examples of oxygen demanding wastes?

Oxygen Demanding Wastes – by Sarah Guessford [Infographic] -Comes from sewage animal feedlots food processing facilities pulp mills runoff from farmlands and dumping of wastes into streams.

What stage of photosynthesis is oxygen produced?

The Light Reactions
The Light Reactions The energy is then temporarily transferred to two molecules ATP and NADPH which are used in the second stage of photosynthesis. ATP and NADPH are generated by two electron transport chains. During the light reactions water is used and oxygen is produced.May 24 2021

When oxygen is released as a result of photosynthesis it is a by product of?

The Two Parts of Photosynthesis

In the light-dependent reactions which take place at the thylakoid membrane chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water. The light-dependent reactions release oxygen from the hydrolysis of water as a byproduct.

Which is the source of oxygen for the product and byproduct of photosynthesis?


The oxygen released during photosynthesis is from the water. The plants will absorb water as well as carbon dioxide during photosynthesis. Later these water molecules are converted into oxygen and sugar.

Can photosynthesis happen without oxygen?

Photosynthetic reactions can occur without oxygen that is anoxygenic thus they do not produce oxygen. … Anoxygenic photosynthesis is the phototrophic process that captures and converts light energy to ATP without producing the oxygen and water is not used as an electron donor.

Why do plants produce oxygen?

Plants make their food in a process called photosynthesis. … Once they have water and carbon dioxide they can use energy from sunlight to make their food. The leftovers from making the plant food is another gas called oxygen. This oxygen is released from the leaves into the air.

Do the plants need oxygen if so what is its source?

Yes plants need oxygen all the free oxygen in the atmospheric air is the result of photosynthesis. No animal can survive without oxygen as it is needed for respiration. Even the plants use the same oxygen in dark for their own respiration.

Why is oxygen important to the electron transport chain?

Oxygen plays a vital role in energy production via a system called electron transport chain (ETC) which is an important component of cellular respiration. … Oxygen acts as a final electron acceptor that helps move electrons down a chain that results in adenosine triphosphate production.

Is oxygen a product of cellular respiration or photosynthesis?

While photosynthesis requires carbon dioxide and releases oxygen cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration.

Why is oxygen the final electron acceptor in cellular respiration?

Explanation: In cellular respiration oxygen is the final electron acceptor. Oxygen accepts the electrons after they have passed through the electron transport chain and ATPase the enzyme responsible for creating high-energy ATP molecules.

What would happen if oxygen disappeared for 5 seconds?

If the world lost its oxygen for five seconds the earth would be an extremely dangerous place to live in. Due to the severe sunburn our inner ear would explode. … Without oxygen there would not any fire and the combustion process in our vehicles would stop. Every mode of transport except electric would fail instantly.

What would happen if oxygen stops to support combustion?

Answer : If oxygen stops to support combustion then there will be no fire because oxygen is essential to carry out combustion. … Fuels can also be used for other non-combustion purposes.

Is life possible without oxygen?

A team of scientists at the Tel Aviv University in Israel have found life-form that can survive without oxygen. … Some lower single-celled organisms or eukaryotes are able to respire without oxygen with a process known as anaerobic respiration.

Which of the following are considered waste products in the photosynthesis reaction?

Carbon dioxide and water (AND sunlight) are taken in the glucose is used by the plant and oxygen is released as a waste product.

What waste product of photosynthesis is released to the environment quizlet?

Sunlight applies the energy needed for photosynthesis to take place. Carbon dioxide and water are converted into glucose (sugar). Oxygen is released into the environment as a waste product of photosynthesis.

How are the waste products of photosynthesis and cellular respiration are essential to the corresponding process?

If oxygen and sugar are a “waste” what are the two needs of photosynthesis to occur. What is and where does the energy come from for photosynthesis to take place? Photosynthesis requires the products of respiration while respiration requires the products of photosynthesis. An organism that cannot make its own food.

How is oxygen produced in light reaction?

During the light reaction in photosynthesis oxygen is released as by product by absorbing light energy by chlorophylls. Source of this oxygen is water. Water splits into hydrogen and hydroxyl ions. The hydroxyl ions released oxygen.
