Respiration

Question 1

Anaerobic respiration (yeast)

Answer 1

C6H12O6 ⟶ 2C2H5OH + 2CO2 + 2ATP.
Glucose ⟶ 2 ethanol + 2 carbon dioxide + 2 ATP

Question 2

Anaerobic respiration (lactic acid)

Answer 2

C6H12O6 ⟶ 2C3H6O3 + 2 ATP
Glucose ⟶ 2 Lactic Acid + 2 ATP

Question 3

Aerobic respiration

Answer 3

C6H12O6 + 6O2 ⟶ 6CO2 + 6H2O

Question 4

Oxygen Debt

Answer 4

• Oxygen required to oxidize lactic acid, created from anaerobic respiration.
• aka EPOC - Excessive Post-exercise Oxygen Consumption

Question 5

Lactic Acid Build Up

Answer 5

• Occurs in muscle cells during vigorous exercise
• Build up in tissues means the more acid produced, the more oxygen is required to react with it.
• Causes burning sensation in muscles.

Question 6

Aerobic (Cycle)

Answer 6

1) Glycolysis - Glucose broken down into 2 Pyruvic acid molecules - 2 ATP + 2NADH
2) Link Reaction - 2NADH
3) Kreb’s Cycle - If pyruvate get oxygen, it goes to the mitochondria to undergo kreb’s cycle - 2FADH, 2ATP, 6NADH
4) ETC - Electron Transport Chain

1 FADH = 2 ATP
1 NADH = 3 ATP

Total = 38 ATP
