5.1 Aerobic respiration and 5.2 Glycolysis Flashcards
1
Q
What is the purpose of aerobic respiration?
A
ATP production
Phosphorylation of compounds to make them more reactive
2
Q
What is ATP used for
A
A source of energy for metabolic processes
3
Q
What are the stages of aerobic respiration and where do they occur?
A
Glycolysis in the cytoplasm
Link reaction in the mitochondrial matrix
Krebs cycle - mitochondrial matrix
Oxidative phosphorylation in the membrane of cristae
4
Q
Outline the process of glycolysis
A
- Phosphorylation of hexose glucose to glucose phosphate using 2 ATP molecules
- Glucose phosphate lysis into 2x triose phosphate
- NAD accept H molecules from each triose phosphate; oxidised to 2x pyruvate
5
Q
What is the net gain of glycolysis?
A
2 NADP
2 ATP
Per glucose molecule
6
Q
How does pyruvate from glycolysis enter the mitochondria?
A
Active transport
