Energy Carriers

Question 1

ATP structure/ high or low energy

Answer 1

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

Question 2

function of ATP

Answer 2

store and provide energy in fixed quantities

powers metabolic reactions

Question 3

advantage of ATP

Answer 3

energy is available for immediate use

Question 4

formation of ATP

Answer 4

ADP + energy + P –> ATP + water

breakdown is the reverse

Question 5

cellular processes of ATP

Answer 5

dark stage of photosynthesis
respiration
protein synthesis

Question 6

ADP structure/ high or low energy

Answer 6

adenosine diphosphate
structure: adenine, ribose, 2 phosphate groups

low energy

Question 7

ADP function

Answer 7

trap and transfer energy

Question 8

cellular processes of ADP

Answer 8

photosynthesis

respiration

Question 9

NAD+ high or low energy

Answer 9

nicotinamide adenine dinucleotide

low energy

Question 10

NAD+ function

Answer 10

trap and transfer H+ ions and electrons

Question 11

cellular process of NAD+

Answer 11

respiration

Question 12

NADH high or low energy

Answer 12

high energy

Question 13

function of NADH

Answer 13

store and provide H+ ions and electrons

Question 14

cellular process of NADH

Answer 14

respiration

Question 15

NADPH high or low energy

Answer 15

high energy

Question 16

NADPH function

Answer 16

store and provide H+ ions and electrons

Question 17

formation of NADPH

Answer 17

NADP+ + 2 electrons + H+ –> NADPH

Question 18

cellular process of NADPH

Answer 18

dark stage of photosynthesis

Question 19

NADP+ high or low energy

Answer 19

nicotinamide adenine dinucleotide phosphate

low energy

Question 20

NADP+ function

Answer 20

trap and transfer H+ ions and electrons

Question 21

NADP+ cellular process

Answer 21

photosynthesis
