What is NADP+ and its role in photosynthesis?

Back

NADP+ is a coenzyme that acts as an electron carrier. It is reduced to NADPH during the light reactions of photosynthesis, which is essential for the Calvin cycle.

What are the light reactions of photosynthesis?

Back

The light reactions are the first stage of photosynthesis, occurring in the thylakoid membranes, where sunlight is converted into chemical energy in the form of ATP and NADPH.

What is the primary function of the Calvin cycle?

Back

The primary function of the Calvin cycle is to produce simple sugars (glucose) from carbon dioxide using ATP and NADPH generated in the light reactions.

Front

Which process does NOT require oxygen?

Back

Glycolysis does not require oxygen; it is an anaerobic process that occurs in the cytoplasm.

Front

How is ATP produced during the light reactions?

Back

ATP is produced during the light reactions through photophosphorylation, utilizing a proton gradient created by the electron transport chain.

What is the role of the proton pump in photosynthesis?

Back

The proton pump helps create a hydrogen ion gradient across the thylakoid membrane, which is used to generate ATP.

Front

What is the significance of the hydrogen ion gradient in photosynthesis?

Back

The hydrogen ion gradient is crucial for ATP synthesis during the light reactions, as it drives ATP synthase to convert ADP and inorganic phosphate into ATP.

What is the difference between aerobic respiration and glycolysis?

Back

Aerobic respiration requires oxygen and includes the Krebs cycle and oxidative phosphorylation, while glycolysis is an anaerobic process that occurs in the cytoplasm.

What is the function of RuBP in the Calvin cycle?

Back

RuBP (ribulose bisphosphate) is a 5-carbon sugar that combines with carbon dioxide to initiate the Calvin cycle, leading to the production of glucose.

Front

What are the products of the light reactions?

Back

The products of the light reactions are ATP and NADPH, which are used in the Calvin cycle to synthesize glucose.
