Respiration- Collins Juju

Question 1

Raw materials needed for cellular respiration

Answer 1

Glucose

Oxygen

Question 2

Products of cellular respiration

Answer 2

Carbon dioxide
Water
ATP (energy)

Question 3

Cellular respiration is a catobolic/anabolic process because energy-rich glucose is broken down/ built up

Answer 3

Catabolic

Broken down

Question 4

Where does the first phase take place?

Answer 4

cystosol

Question 5

Where does the second and third phases take place

Answer 5

mitochodria

Question 6

List the three different stages in the the aerobic respiration phase

Answer 6

Glycolysis
Krebs cycle
Oxidative phosphorylation

Question 7

Glycolysis occurs in the…..?

The phase requires no oxygen and is therefore….?

Answer 7

Cytosol

Anaerobic

Question 8

List the similarities between aerobic and anaerobic respiration

Answer 8

Glucose serves as a raw material in both processes
Carbon dioxide is released in both processes
Energy is released in both processes

Question 9

List four differences between aerobic and anaerobic respiration

Answer 9

Aerobic respiration
*It occurs in the presence of oxygen

• Products are carbon dioxide
• A large amount of energy is released because glucose molecule is broken down completely
• It takes place in the cytosol and inside the mitochondrian

Anaerobic Respiration
*It occurs in the absence of oxygen

• Products are lactic acid or carbon dioxide and ethanol
• A small amount of energy is released because the glucose molecule is only broken down partially
• It only takes place in the cytosol

Question 10

The role of anaerobic respiration in industry

Answer 10

Making beer, cheese, wine,and baking bread

Question 11

Define the term cellular respiration

Answer 11

Is the breaking down of organic compounds with the gradual release of energy that is stored in ATP molecules. Oxygen is required and carbon dioxide and water are released as waste products.
