Cellular respitarion & fermentation

Question 1

Where does glycolysis occur?

Answer 1

cytoplasm

Question 2

Where does the krebs cycle (citric acid cycle) occur?

Answer 2

mitochondrial matrix

Question 3

Where is the electron transport chain located?

Answer 3

the inner membrane of the mitochondria

Question 4

What is the chemical formula for cellular respiration?

Answer 4

C6 H12 O6 + 6O2 -> 6CO2 + 6H2O + ATP (energy)

Question 5

Which step makes the most ATP?

Answer 5

Electron Transport Chain

Question 6

What does the krebs cycle break down?

Answer 6

Acetyl CoA

Question 7

What does the krebs cycle produce?

Answer 7

ATP, NADH, and FADH2 molecules.

Question 8

In the krebs cycle, 1 glucose is completely broken down in 2 turns. What does it create?

Answer 8

6 NADH, 2 ATP, 2 FADH2, 4 CO2

Question 9

What serves as the final electron acceptor in the etc?

Answer 9

Oxygen

Question 10

What does glycolysis do?

Answer 10

Converts glucose into pyruvic acid

Question 11

What does glycolysis produce?

Answer 11

Glycolysis produces ATP and NADH when glucose is converted into pyruvic acid

Question 12

What are the electron acceptors?

Answer 12

NAD+ and FAD+

Question 13

What are the electron carriers?

Answer 13

NADH and FADH2

Question 14

What does anaerobic mean?

Answer 14

Requires no oxygen

Question 15

What does aerobic mean?

Answer 15

Requires oxygen

Question 16

What does glycolysis break down?

Answer 16

Breaks 1 glucose (6-carbon) molecule into 2 pyruvic acid (3-carbon) molecules.

Question 17

How much atp is used in the process of glycolysis?

Answer 17

2

Question 18

How many ATP does each cell produce per glucose?

Answer 18

It varies, but usually 36 ATP per glucose.

Question 19

What happens during the krebs cycle?

Answer 19

Pyruvic acid is converted into CO2 and water in the presence of oxygen, producing a large amount of ATP.
