KC: Photosynthesis - LDR

Front

What are the two processes by which ATP is formed in the light dependent reactions?

Back

Passive transport of H+ from high to low concentration & phosphorylation.

Front

What are the two main products of the light reactions that are essential for the Calvin cycle?

Back

NADPH and ATP.

Front

What role does sunlight play in photosynthesis?

Back

Sunlight is used to break down water.

Front

Where do the light dependent reactions occur in the chloroplast?

Back

In the thylakoid.

Front

What molecule can gain H+ and electrons during photosynthesis?

Back

NADP+.

Front

What is the primary function of the light dependent reactions?

Back

To convert solar energy into chemical energy in the form of ATP and NADPH.

Front

What is the significance of H+ ions in the light dependent reactions?

Back

H+ ions create a proton gradient that drives ATP synthesis.

Front

What is the role of NADPH in photosynthesis?

Back

NADPH provides the reducing power for the Calvin cycle.

Front

How does the electron transport chain function in the light dependent reactions?

Back

It transfers electrons from water to NADP+, releasing energy used to pump H+ ions.

Front

What is photolysis and its importance in photosynthesis?

Back

Photolysis is the splitting of water molecules, providing electrons and H+ ions for the light reactions.
