When Oxygen Is Released As A Result Of Photosynthesis It Is A Direct By-Product Of

Which of these phosphorylates ADP to ATP?

Terms in this set (10) ATP synthase phosphorylates ADP.

What molecule is split in the oxygen releasing light reactions of photosynthesis?

In the light-requiring reactions of photosynthesis water molecules (H2O) are split apart by light energy (captured by photosynthetic pigments). Oxygen atoms released from the splitting of water molecules combine in pairs forming O2 molecules and these diffuse out of the leaf through the stomates.

Why can C4 plants photosynthesize without?

Why are C4 plants able to photosynthesize with no apparent photorespiration? They use PEP carboxylase to initially fix CO2. fix CO2 into organic acids during the night. The alternative pathways of photosynthesis using the C4 or CAM systems are said to be compromises.

Is oxygen the final electron acceptor?

Oxygen is the final electron acceptor in this respiratory cascade and its reduction to water is used as a vehicle by which to clear the mitochondrial chain of low-energy spent electrons.

Where do electrons end up in photosynthesis?

The electrons must travel through special proteins stuck in the thylakoid membrane. They go through the first special protein (the photosystem II protein) and down the electron transport chain. Then they pass through a second special protein (photosystem I protein).

What very important molecule is the direct product of photosynthesis?

What molecule is the direct product of photosynthesis? How is that molecule then used by plant cells? The Calvin cycle produces G3P which plant cells can use as a raw material to produce glucose and other molecules such as starch and cellulose.

What is ADP and NADP?

ATP – Adenosine triphosphate. ADP – Adenosine diphosphate. NADP – Nicotinamide adenine dinucleotide phosphate. NADPH – The reduced form of NADP. In the Light Dependent Processes i.e Light Reactions the light strikes chlorophyll a in such a way as to excite electrons to a higher energy state.

What happens to CO2 in the Calvin cycle?

What happens to carbon dioxide molecules in the Calvin cycle reactions? carbon dioxide molecules are bonded together with the electrons and H’s from NADPH to form glucose. … cO2 goes in and O2 comes out. it helps to exchange them using simple diffusion.

What happens to CO2 levels during photosynthesis?

Photosynthesis separates carbon dioxide and water — known as CO2 and H2O respectively — into their individual molecules and combines them into new products. Once the process is done the plant releases Oxygen or O2 into the surrounding air.

Is released during photosynthesis True or false?

Photosynthesis takes place in mesophyll cells. From the above information we have found that carbon dioxide is not released during photosynthesis. Instead of it oxygen is released. Hence the correct answer is option (B).

What do plants produce during photosynthesis?

During the process of photosynthesis cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell such as glucose.

Do plants need oxygen for photosynthesis?
