1
Q

ATP structure/ high or low energy

A

adenosine triphosphate
structure: adenine, ribose, 3 phosphate groups
high energy, unstable bond with 3rd phosphate so loses energy quickly

2
Q

function of ATP

A

store and provide energy in fixed quantities

powers metabolic reactions

3
Q

advantage of ATP

A

energy is available for immediate use

4
Q

formation of ATP

A

ADP + energy + P –> ATP + water

breakdown is the reverse

5
Q

cellular processes of ATP

A

dark stage of photosynthesis
respiration
protein synthesis

6
Q

ADP structure/ high or low energy

A

adenosine diphosphate
structure: adenine, ribose, 2 phosphate groups

low energy

7
Q

ADP function

A

trap and transfer energy

8
Q

cellular processes of ADP

A

photosynthesis

respiration

9
Q

NAD+ high or low energy

A

nicotinamide adenine dinucleotide

low energy

10
Q

NAD+ function

A

trap and transfer H+ ions and electrons

11
Q

cellular process of NAD+

A

respiration

12
Q

NADH high or low energy

A

high energy

13
Q

function of NADH

A

store and provide H+ ions and electrons

14
Q

cellular process of NADH

A

respiration

15
Q

NADPH high or low energy

A

high energy

16
Q

NADPH function

A

store and provide H+ ions and electrons

17
Q

formation of NADPH

A

NADP+ + 2 electrons + H+ –> NADPH

18
Q

cellular process of NADPH

A

dark stage of photosynthesis

19
Q

NADP+ high or low energy

A

nicotinamide adenine dinucleotide phosphate

low energy

20
Q

NADP+ function

A

trap and transfer H+ ions and electrons

21
Q

NADP+ cellular process

A

photosynthesis
