Question 1

Cellular respiration

Answer 1

The process by which an organism uses the food it consumes to produce energy

Question 2

What organelle is involved in cellular respiration?

Answer 2

The mitochondria

Question 3

Aerobic respiration

Answer 3

When oxygen is present

Question 4

Anaerobic respiration

Answer 4

When oxygen is absent

Question 5

Stages of cellular respiration if oxygen is present

Answer 5

Glycolysis
Prep-Step
Krebbs cycle
Electron transport chain

Question 6

Stages of cellular respiration if oxygen is not present

Answer 6

Glycolysis
Fermentation

Question 7

Where does glycolysis occur

Answer 7

In the cytoplasm

Question 8

What happens during glycolysis

Answer 8

One molecule of glucose is broken down into 2 molecules of pyruvic acid

Question 9

What is required to start glycolysis

Answer 9

2 atp molecules

Question 10

How many ATP molecules are produced during glycolysis

Answer 10

4

Question 11

What is the net production of ATP during glycolysis. What else is produced during glycolysis?

Answer 11

2 ATP
2 NADPH

Question 12

Lactic acid fermentation

Answer 12

Occurs in muscle cells when there isn’t enough oxygen

Question 13

Alcoholic fermentation

Answer 13

occurs in yeast

Question 14

Does either fermentation pathway produce ATP

Answer 14

No

Question 15

Prep-Step

Answer 15

When each pyruvic acid made during glycolysis is modified so it can enter the Krebbs cycle.

Question 16

What is produced during the Krebbs cycle

Answer 16

NADH, FADH2, ATP, and carbon dioxide

Question 17

Where does the Krebbs cycle occur

Answer 17

The mitochondrial matrix

Question 18

Where does the electron transport chain take place

Answer 18

The inner mitochondrial membrane

Question 19

What happens in the electron transport chain?

Answer 19

The electrons trapped by NADH and FADH2 will be used to generate ATP

Question 20

How many ATP are made during cellular respiration

Answer 20

36 ATP
