Ch 4 Cellular Respiration

Question 1

What is the purpose of cellular respiration?

Answer 1

To produce ATP for the cell

Question 2

What are the reactants in cellular respiration?

Answer 2

C6H12O6 and O2

Question 3

What are the products of cellular respiration?

Answer 3

6H2O and 6C02

Question 4

What must happen before the Krebs cycle can begin?

Answer 4

Glycolysis

Question 5

What are the reactants of glycolysis

Answer 5

2 pyruvate
4ATP
2NADH

Question 6

What does a cell need to do Glycolysis?

Answer 6

glucose (C6H12O6)
2 ATP
2NAD+

Question 7

Is glycolysis an aerobic or anaerobic process?

Answer 7

Anaerobic

Question 8

What is the difference between aerobic and anaerobic processes?

Answer 8

Anaerobic doesn’t need oxygen to happen

Aerobic needs Oxygen

Question 9

What is the purpose of fermentation?

Answer 9

To provide NAD+ so glycolysis can continue?

Question 10

Why does fermentation occur?

Answer 10

Because there isn’t enough oxygen present to enter the krebs cycle. So to keep some ATP production going the body continues doing glycolysis.

Question 11

What are the reactants of the Krebs cycle?

Answer 11

Oxygen and Pyruvate

Question 12

What are the products of the Krebs cycle?

Answer 12

NADH, FADH2, a few ATP, CO2 Release as waste

Question 13

What are the reactants of the electron transport chain?

Answer 13

Oxygen NADH, FADH2

Question 14

What are the products of the electron transport chain?

Answer 14

H20 released as waste and about 30 ATP

Question 15

How many ATP total can be made under ideal conditions using just one molecule of glucose?

Answer 15

38

Question 16

Where does aerobic respiration take place?

Answer 16

in the Mitochondria

Question 17

Where does the Krebs Cycle take place?

Answer 17

In the matrix of the mitochondria

Question 18

Where does the Electron Transport Chain take place?

Answer 18

In the inter membrane folds of the mitochondria, also called the cristae
