How Does Oxygen Production Relate To The Rate Of Photosynthesis


How Does Oxygen Production Relate To The Rate Of Photosynthesis?

In photosynthesis oxygen along with glucose is produced as result of carbon dioxide and water molecule reaction. More oxygen means higher rate of photosynthesis.

How can oxygen production show the rate of photosynthesis?

The production of oxygen by photosynthesis is most easily seen in water plants such as Elodea and Cabomba. The number of bubbles released in a given time can be counted as a measure of the rate of photosynthesis. … In this experiment move the syringe to draw the oxygen produced into the capillary tubing.

How does oxygen production relate to the rate of photosynthesis quizlet?

How does oxygen production relate to the rate of photosynthesis? A greater flow of oxygen corresponds to a higher rate of photosynthesis.

What does oxygen production have to do with photosynthesis?

During photosynthesis plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. … 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.

What affects the rate of photosynthesis?

Three factors can limit the rate of photosynthesis: light intensity carbon dioxide concentration and temperature.

What is the difference between photosynthesis rate and net photosynthesis rate which rate are you determining in this procedure explain?

Photosynthesis rate or gross photosynthesis rate is the total rate of fixation of carbon (reduction of CO2) without considering the amount of CO2 lost during respiration. Net photosynthesis rate is the rate of carbon fixation after subtracting the percentage of CO2 lost during the respiration.

Where is oxygen produced in photosynthesis?

The chloroplast is involved in both stages of photosynthesis. The light reactions take place in the thylakoid. There water (H2O) is oxidized and oxygen (O2) is released.

What is the rate of photosynthesis?

The rate of photosynthesis is a gross measure of the rate at which a plant captures radiant energy and fixes it in organic carbon compounds.

Where is oxygen gas produced?


We humans along with many other creatures need oxygen in the air we breathe to stay alive. Oxygen is generated during photosynthesis by plants and many types of microbes. Plants both use oxygen (during respiration) and produce it (via photosynthesis).

Is oxygen produced during photosynthesis experiment?

Observation: Gas bubbles in a test tube. Result: Presence of oxygen. Conclusion: Formation of gas bubbles prove that oxygen is produced by the green plants during photosynthesis.

What happens to oxygen released during photosynthesis apex?

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. The oxygen is then released into the atmosphere whereas the sugar molecules are stored for energy.

What are five factors that affect the rate of photosynthesis?

Temperature light intensity carbon dioxide levels water oxygen and chlorophyll. The rate of photosynthesis increases as the temperature increases.

What are the four factors that affect the rate at which photosynthesis occurs?

Factors affecting photosynthesis
  • the rate of oxygen output.
  • the rate of carbon dioxide uptake.
  • the rate of carbohydrate (glucose) production.

How does light intensity affect oxygen production?

Oxygen production increased as the light intensity increased due the greater availability of light energy for photosynthesis.

How is the rate of photosynthesis expressed what factors affect the photosynthetic rate?

Carbon dioxide concentration

Carbon dioxide – with water – is one of the reactants in photosynthesis. If the concentration of carbon dioxide is increased the rate of photosynthesis will therefore increase. Again at some point a factor may become limiting.

What happens when the rate of photosynthesis exceeds the rate of respiration?

If the rate of respiration exceeds the rate of photosynthesis the plant will be using more oxygen than it can produce. Thus the plant will be starved of food supply and finally die of starvation.

What is the difference between net photosynthesis and photosynthesis?

Net photosynthesis is true photosynthesis minus photorespiration and dark respiration. GPP is intended as an integration of apparent photosynthesis (true photosynthesis minus photorespiration) NOT gross (true) photosynthesis.

When and how is oxygen released as a by product in the photosynthesis?

All photosynthetic eukaryotic cells contain chloroplasts that use the radiant energy of sunlight to convert carbon dioxide and water into carbohydrates. As a byproduct of photosynthesis oxygen gas is also released into the atmosphere through tiny openings in the leaves called stomata.

How can the rate of photosynthesis be increased?

As light intensity increases the rate of photosynthesis will increase as long as other factors are in adequate supply. … If carbon dioxide and light levels are high but temperature is low increasing temperature will have the greatest effect on reaching a higher rate of photosynthesis.

What is the rate of photosynthesis controlled by?

The chemical reactions involved in photosynthesis are controlled by enzymes . As with any other enzyme-controlled reaction the rate of photosynthesis is affected by temperature. At low temperatures the rate of photosynthesis is limited by the number of collisions between enzymes and substrate.

What is the source of o2 evolved during photosynthesis?

the sources of oxygen evolved during photosynthesis In the process of photosynthesis oxygen is produced from the photolysis of water. The photolysis of water occurs when light is used to renew split water and adenosine triphosphate also referred to as ATP.

How do oxygen plants produce oxygen?

One is by liquifying air through a process called cryogenic distillation. In this method oxygen is produced in air separation plants where the air is cooled and the oxygen is distilled based on its boiling point. … Oxygen can also be generated from the air itself by a machine called an oxygen concentrator.

What stage of photosynthesis is o2 produced?

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

Why oxygen is evolved during photosynthesis?

Oxygen evolves in the process of photosynthesis by photolysis of water occurring in membranes of grana thylakoids. … Oxygen evolves during light reaction due to the splitting of water. Water splits into H+ O and electrons. The oxygen and proton formed by the splitting of water are liberated in the lumen of thylakoids.

Is oxygen needed for photosynthesis?

By using the energy of sunlight plants can convert carbon dioxide and water into carbohydrates and oxygen in a process called photosynthesis. As photosynthesis requires sunlight this process only happens during the day. … Oxygen is required to do this.

How the oxygen is produced?

The most common commercial method for producing oxygen is the separation of air using either a cryogenic distillation process or a vacuum swing adsorption process. Nitrogen and argon are also produced by separating them from air. … This method is called electrolysis and produces very pure hydrogen and oxygen.

What happens to the oxygen released during photosynthesis answers com?

They take in carbon dioxide and oxygen through pores in their leaves called stomata. Using the sugar they created during photosynthesis and this oxygen their mitochondria create ATP.

Why is the oxygen production of the plants different at different times of the day?

During the day photosynthesis is dominant so there is a net release of oxygen. At night photosynthesis stops but respiration continues so there is a net consumption of oxygen. The compensation point is where the net change in oxygen is zero.

How do we know that the oxygen released in photosynthesis comes from water?

Scientists confirmed van Niel’s hypothesis that oxygen released from photosynthesis comes from water with the use of 18O a heavy isotope as a tracer to follow the fate of oxygen atoms during photosynthesis. The experiments showed that the O2 from plants was labeled with 18O only if water was the source of the tracer.

How will cellular respiration affect oxygen levels?

This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar. … When the cell uses oxygen to break down sugar oxygen is used carbon dioxide is produced and energy is released.

What are the factors that affect the rate of photosynthesis which is considered the most important?

The amount of light the carbon dioxide supply temperature water supply and the availability of minerals are the most important environmental factors that affect the rate of photosynthesis in land plants.

What factors speed up or slow down the rate of photosynthesis?

The environmental factors that speed up or slow down the rate of photosynthesis are temperature and the availability of sunlight and carbon dioxide. …

What does not affect the rate of photosynthesis?

Photosynthesis is affected by light temperature water and CO2. Stomata affect the process of transpiration and do not affect photosynthesis.

How does light affect oxygen production in photosynthesis?

As the light levels are increased there is an increase in oxygen (bubble) production from photosynthesis of the plant. This increase slows down progressively at higher light levels.
