How does a competitive inhibitor affect enzyme activity?

Back

A competitive inhibitor binds to the active site of an enzyme, preventing it from catalyzing the reaction.

Why do plants not perform photosynthesis at night?

Back

Plants do not perform photosynthesis at night because they lack an energy source to power the light reactions.

What is the function of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily from the blue and red wavelengths, to drive the photosynthesis process.

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.

What is the significance of the electron transport chain (ETC) in cellular respiration?

Back

The ETC is crucial for ATP production, as it uses electrons from NADH and FADH₂ to create a proton gradient that drives ATP synthesis.
