Glycolysis Flashcards
1
Q
Anabolism
A
- Synthesis of molecules and complex structures from the building blocks of life
- Requires energy
2
Q
Catabolism
A
- Breakdown of molecules to obtain the anabolic ‘building blocks’ of life and substrates for energy
- Breakdown of molecules to yield energy
3
Q
What is metabolism?
A
Anabolism and cataboism working together
4
Q
Glucose
A
- Most important carbohydrate
- Primary energy source
- Oxidised to CO2 and H2O
5
Q
How does glucose get into a cell?
A
- Via glucose transporters (GLUT)
- By facilitated diffusion
6
Q
What is glycolysis?
A
The initial pathway for the conversion of glucose to pyruvate
7
Q
What is the net gain of ATP in glycolysis per glucose?
A
Net gain of 2ATP per glucose (uses 2 ATP then gains 4 ATP)
8
Q
Process of glycolysis
A
- Hexokinase phosphorylates glucose
- Phosphofructokinase phosphorylates fructose-6-phosphate
- Pyruvate kinase converts phosphoenolpyruvate to pyruvate
