Anerobic Respiation

Question 1

Where is ATP produced in anaerobic respiration

Answer 1

Glycolysis

Question 2

Anaerobic respiration in animals

Answer 2

• only glycolysis continues
  -reduced NAD + pyruvate —> oxidised NAD ( for further glycolysis) + lactate

Question 3

What happens to lactate produced in anaerobic respiration

Answer 3

Transported to liver is bloodstream where its oxidised to pyruvate

Can enter link section in liver cells or be converted to glycogen

Question 4

Anaerobic respiration in plant and yeast

Answer 4

• only glycolysis continues
• pyruvate is decarboxylate to form ethanal
• ethanal is reduced to ethanol using reduced NAD to produce oxidised NAD for further glycolysis

Question 5

Advantage of producing lactate and ethanol

Answer 5

Converts reduced NAD back into NAD s glycolysis can continue

Question 6

Disadvantage of producing ethanol

Answer 6

• Cell die when ethanol conc to high
• ethanol dissolves cel membranes

Question 7

Disadvantage of producing lacate during anaerobic respiration

Answer 7

• Acidic so decreases pH
• results in muscle fatigue
