1

Where does the calvin cycle take place?

stroma

2

What is the point of regeneration?

to create RuB

3

What are the 3 phases of the Calvin cycle?

Carbon Fixation, Reduction, Regeneration,

4

What are the 3 fates of pyruvate?

1. Ethanol
2. Lactate
3. CoA

5

What is PFK?

An enzyme,

6

What is the equation for cellular respiration?

C6H12O2

7

Where does cellular respiration occur?

Cytosol, mitochondria

8

What do you have to add to atp to get the bond to break?

Water

9

What is a nucleotide?

Nitrogenous base, sugar, phosphate

10

What are the 5 nitrogenous bases?

Guanine
Cytosine
Adenine
Thymine
Uracil

11

What enzyme uses ATP to make energy?

ATPase

12

Using redox reactions, what does it need to make ATP?

Glucose, Oxygen,

13

What are coenzymes?

electron carriers, NAD+ (can accept 1 proton, 2 electrons), FAD (2 protons, 2 electrons)

14

What is an inhibitor?

Competitive inhibitor fills enzyme, Non-Competitive changes allosteric site

15

Where does glycolysis occur?

Cytosol

16

How many ATP does Glycolysis make?

4

17

How many ATP are made in the electron transport chain?

34

18

What are the 2 phases of glycolysis?

Energy investment, energy payoff,

19

What is the cyclic electron flow?

There is enough NADPH in the cell, so instead it makes ATP in the electron transport chain

20

What are the 3 phases of cellular respiration?

Glycolysis, Kreb's cycle, Electron transport chain,

21

What is the final product of glycolysis?

pyruvate

22

What is the point of the Kreb's cycle?

Create FAD, NADH and CO2

23

What are the two main products of the electron transport chain?

ATP, Water,

24

What is the coenzyme / electron carrier for glycolysis?

NAD+

25

How many ATP gets made in energy investment?

2

26

How many ATP gets made in energy payoff?

4

27

What is PFK for?

an enzyme, inhibited by citric acid and ATP

28

What do you need PFK for?

Glycolysis

29

What are the isomers during glycolysis?

PGAL

30

What is an isomer?

same chemical formula, look different
