Question 1

What is the equation for cellular respiration?

Answer 1

C6H12O6 —> 6CO2+6H20
+30 net atp (EUK) or
+32 net atp (PROK)

Question 2

What is ATP made up of?

Answer 2

3 phosphates, adenine nitrogenous base, ribose (pentose sugar)

Question 3

Are the bonds between the phosphates in ATP stable or unstable?

Answer 3

unstable (like magnets)

Question 4

How is ATP broken

Answer 4

Hydrolysis

Question 5

What is the phosphate that pops off ATP called

Answer 5

inorganic phosphate (it’s not connected to a carbon and hydrogen)

Question 6

What type of reaction is the breaking off of the phosphate (endergonic or exergonic)

Answer 6

exergonic because it’s breaking down

Question 7

What are the 2 ways to make ATP

Answer 7

substrate level phosphorylation and oxidative phosphorylation

Question 8

What enzyme is used in oxidative phosphorylation

Answer 8

ATP synthase

Question 9

What happens in oxidative phosphorylation

Answer 9

a free Pi is attached to ADP

Question 10

What enzyme is used in substrate level phosphorylation

Answer 10

a kinase

Question 11

What happens in substrate level phosphorylation

Answer 11

transfer of P from an organic molecule to ADP

Question 12

What reactions form ATP

Answer 12

exergonic

Question 13

ATP drives what kind of reactions

Answer 13

endergonic (it’s used to do cellular work)

Question 14

What is energy coupling

Answer 14

using the energy from a spontaneous process to power a non-spontaneous process

Question 15

What is oxidation

Answer 15

loss of electrons

Question 16

what is reduction

Answer 16

gain of electrons

Question 17

During cellular respiration what is oxidized and what is reduced

Answer 17

glucose (C6H12O6) is oxidized to 6CO2
oxygen (6O2) is reduced to 6H2O
