Glycolysis

Question 1

Where does glycolysis take place?

Answer 1

The cytoplasm

Question 2

Aerobic or anaerobic respiration?

Answer 2

Both

Question 3

Stage 1

Answer 3

Glucose (6 carbon) is phosphorylated, 2 phosphate groups added using ATP (it gets hydrolysed into ADP and Pi)

Question 4

Stage 2

Answer 4

Phosphorylated glucose is really unstable, it breaks down into 2 triose phosphate (3 carbons each, 1 phosphate each)

Question 5

stage 3

Answer 5

The triose phosphate are oxidised, they lose a hydrogen each which is accepted by NAD which becomes NADH. 4 ATP is also released here via substrate level phosphorylation.

Question 6

Stage 4

Answer 6

two pyruvate (3 carbon molecules) created

Question 7

what are the products of glycolysis?

Answer 7

2 NADH
2 pyruvate
2 Net gain of ATP

Question 8

how is the mitochondria adapted to its function?

Answer 8

large surface area due to presence of cristae- which enables the membrane to hold many electron transport chains and ATP synthase enzymes
