KC: Photosynthesis - LDR

Front

What is the purpose of splitting water in PS2 (photosystem 2) of the light dependent reaction?

Back

Provides electrons for the electron transport chain and protons (H+) for the thylakoid space.

Front

What supplies the electrons that travel down the electron transport chain (ETC) during the light reactions?

Back

Water.

Front

Which of the following is NOT a product of the light reactions: ATP, NADPH, or Glucose?

Back

Glucose.

Front

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

Back

NADPH and ATP.

Front

How do protons (H+) move into the thylakoid space during the light reactions?

Back

Due to the movement of electrons through the electron transport chain.

Front

What is the role of Photosystem II in the light-dependent reactions?

Back

To absorb light energy and initiate the splitting of water.

Front

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

Back

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

Front

What is produced as a byproduct of water splitting in Photosystem II?

Back

Oxygen.

Front

What is the significance of the proton gradient created during the light reactions?

Back

It drives ATP synthesis through ATP synthase.

Front

What are the light-dependent reactions of photosynthesis primarily responsible for?

Back

Converting light energy into chemical energy in the form of ATP and NADPH.
