Question

Part 1

The energy that is released when hydrogen ions pass through ATP synthase provides the energy needed to form ADP and phosphate from ATP.

True/False

Part 2

Photosystem I occurs before photosystem II during the light reactions.

Part 3

A photosystem can best be described as

Multiple Choice

an area within the cristae of the mitochondria that is responsible for generating ATP.

a collection of pigments that is responsible for generating glucose sugar.

a collection of high-energy electrons that transfer energy to energy carriers, generating ATP.

a collection of pigments that trap solar energy and focus it on reaction centers, releasing high-energy electrons.

Part 4

After high-energy electrons leave photosystem II, they proceed directly to ______, where their energy is used to _______.

Multiple Choice

photosystem II; generate a new round of high-energy electrons

photosystem I; convert ADP into ATP

photosystem I; reduce NADP+ to NADPH

the electron transport chain; convert ADP into ATP

Part 5

In which of the following ways is photosystem I different than photosystem II?

Multiple Choice

Photosystem I uses the high-energy electrons to reduce NADP+ to NADPH, whereas photosystem II uses them to convert ADP into ATP.

Photosystem II captures solar energy, whereas photosystem I does not.

Photosystem I recycles its high-energy electrons, whereas photosystem II passes them off to the electron transport chain.

Photosystem II contains a pigment complex to trap energy, whereas photosystem I does not.

Part 1: True

Hydrogens pumped across the mitochondrial membrane form proton gradient, they pass through the ATP synthase converting ADP to ATP

Part 2 false

Photosystem II functions before photosystem I.
