The two main types of photosystems are:

• Photosystem II and Photosystem I

• Photosystem A and Photosystem B

• Photosystem Alpha and Photosystem Beta

• Photosystem X and Photosystem Y

A proton gradient is created by:

• the movement of protons across a membrane during cellular respiration or photosynthesis

• the breakdown of ATP molecules

• the synthesis of glucose molecules

• the transfer of electrons to oxygen

What happens during water splitting?

• Water is combined with oxygen.

• Water is split into hydrogen and oxygen.

• Water is converted into ice.

• Water is evaporated into steam.

What happens in Photosystem I?

• Photosystem I absorbs light and transfers energy and electrons.

• Photosystem I is responsible for the synthesis of ATP.

• Photosystem I splits water molecules to release oxygen.

• Photosystem I is involved in the Calvin cycle.
