Glycolysis

Question 1

2 phases

Answer 1

1. Energy investment
   - ATP is utilised to break 6C glucose into 2 3C sugars
2. Energy payoff
   - energy is released when 2 3C undergo rearrangement to form 2ATP and 2NADH

Question 2

Occurs at?

Answer 2

Cytosol

Question 3

Pdts?

Answer 3

Net gain of 2ATP by substrate level phosphorylation

Question 4

Two impt rns in glycolysis

Answer 4

1. SLP
   - overall net gain of 2 ATP per molecules
2. Reduction of NAD
   - GALP is oxidised by dehydrogenation
   - coenzyme NAD+ is reduced to NADH
