What is the Calvin Cycle?

Back

The Calvin Cycle is a series of biochemical reactions that take place in the stroma of chloroplasts in photosynthetic organisms, where carbon dioxide is converted into glucose using ATP and NADPH produced in the light-dependent reactions.

Front

What are the main products of the light-dependent reactions of photosynthesis?

Back

The main products are Oxygen, NADPH, and ATP.

Front

How do plants obtain carbon for glucose synthesis?

Back

Plants obtain carbon through CO2 absorbed from the atmosphere.

Front

What role does ATP play in the Calvin Cycle?

Back

ATP provides the energy required to convert carbon dioxide into glucose during the Calvin Cycle.

Front

What is the function of NADPH in photosynthesis?

Back

NADPH acts as a reducing agent, providing the electrons needed to convert carbon dioxide into glucose in the Calvin Cycle.

Front

What is the significance of the enzyme's shape?

Back

An enzyme's shape determines its function, as it must fit the substrate to catalyze a reaction.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment that absorbs light energy, primarily from the sun, which is essential for the light-dependent reactions of photosynthesis.

Front

What is photolysis in the context of photosynthesis?

Back

Photolysis is the process of splitting water molecules into oxygen, protons, and electrons using light energy during the light-dependent reactions.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration occurs without oxygen and produces less ATP.

Front

What is the role of ATP synthase in cellular respiration?

Back

ATP synthase is an enzyme that synthesizes ATP from ADP and inorganic phosphate during oxidative phosphorylation.
