Q

Why is hydrolysis of water necessary as it relates to psi and light dependent reactions

A

Hydrogen molecules form the splitting of water are released into thylakoid space and used to create an electrochemical/ proton gradient

17
Q

When electrons are transferred between molecules in a reaction they pass through

A

Electron transport chain

18
Q

How are psll Psl functionally related to electron transport chain ?

A

Pass high energy electrons to the etc

19
Q

What is an electrochemical/ proton gradient ?

A

It is a difference in concentration of protons (hydrogen ions) across a membrane

20
Q

What is ATP synthase ?

A

An enzyme that creates ATP when protons pass through the enzyme

21
Q

Goal of Calvin cycle

A

Make organic products that plants need using products from the light reactions of photosynthesis

22
Q

Product of light reaction

A

Atp 02 NADPH
