Respiration: Anaerobic

Question 1

AR: Step 1

Answer 1

Glycolysis

Question 2

AR: Step 2

Answer 2

• Pyruvate gains a hydrogen
  -reduced by NADH -> NAD
• NAD can be reused in glycolysis to ensure ATP production
• Produces lactate

Question 3

Impermanence

Answer 3

• Lactate is an acid so will begin to denature enzymes so reactions cannot continue to occur
• smaller amounts of ATP made
• Ethanol toxic so would denature enzymes

Question 4

Plants and Microobes

Answer 4

• produces Ethanol and CO2 not lactate due to different enzymes

Question 5

Aerobic respiration efficiency

Answer 5

• Should produce 28 ATP/ glucose
• 32% efficiency e.g. heat loss, active transport

Question 6

Anaerobic respiration efficiency

Answer 6

• doesn’t fully break down glucose
• 2ATP/ glucose
