Respiration

Question 1

Name the 4 main stages in aerobic respiration and where they occur.

Answer 1

Glycolysis: cytoplasm
Link reaction: mitochondrial matrix
Krebs cycle: mitochondrial matrix
Oxidative phosphorylation via ETC: membrane of cristae

Question 2

Outline the stages of glycolysis.

Answer 2

1. Glucose is phosphorylated to GP by 2x ATP
2. GP splits into 2x TP
3. 2x TP is oxidised to 2x pyruvate
   Net gain of 2x reduced NAD & 2x ATP per glucose
