Q

What is ATP Synthase synthesized by?

A

Chemiosmosis

16
Q

For 1 molecule of glucose, how many ATP are made?

A

Roughly 30

17
Q

How does the electron transport chain extract energy?

A

By creating a proton gradient

18
Q

If O2 isn’t the final e- acceptor, what is?

A

CO2, or methanogens. AKA anaerobic respiration

19
Q

What is the last e- acceptor in chemical respiration?

A

H2O

20
Q

What is the formula for photosynthesis?

A

6CO2 + 12H2O + light <> C6H12O6 + 6H2O + 6O2

21
Q

Where does photosynthesis take place?

A

Stroma or cytoplasm. It has enzymes to make large C chains

22
Q

How do you know the reverse of photosynthesis is aerobic respiration?

A

If you go backwards, the final e- acceptor is H2O, producing water

23
Q

What happens in light dependent stage of photosynthesis?

A

It’s where we get e- and ATP.

24
Q

What happens in light independent stage of photosynthesis?

A

It’s where we use ATP to make glucose

25
Q

What is the e- acceptor in photosystem 2?

A

NADP+
