Front

Where do the light reactions of photosynthesis occur?

Back

In the thylakoid membrane.

Front

Where do the dark reactions of photosynthesis take place?

Back

In the stroma.

Front

What does competitive inhibition involve?

Back

A molecule, other than the substrate, binding to the enzyme’s active site.

Front

What is the by-product of splitting water molecules during photosynthesis?

Back

Oxygen.

Front

Which process does not occur in the mitochondria?

Back

Glycolysis.

Front

What is the role of NADP+ in photosynthesis?

Back

It acts as an electron carrier, being reduced to NADPH.

Front

What is chemiosmosis?

Back

The process of ATP production in the chloroplasts and mitochondria, driven by a proton gradient.

Front

What is the function of the electron transport chain in photosynthesis?

Back

To transfer electrons and create a proton gradient for ATP synthesis.

Front

What is the main purpose of the Krebs cycle?

Back

To produce electron carriers (NADH and FADH2) for the electron transport chain.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen, while anaerobic respiration does not.
