Question 2

Anaerobic steps

Answer 2

1. glycolysis
2. fermentation

Question 3

Glycolysis

Answer 3

start- glucose
end- 2 pyruvate, 2 ATP, 2 NADH

Question 4

Fermentation

Answer 4

regenerates NAD+ from NADH

Question 5

Lactic acid

Answer 5

LDH convert pyruvate into lactate which then oxidizes NADH into NAD+

Question 6

Alchohol/ ethanol

Answer 6

pyruvate–>acetaldehyde releasing Co2

Question 7

Oxidation of Pyruvate products

Answer 7
