Glycolysis Flashcards
1
Q
Steps of glycolysis
A
- Priming reactions
- Cleavage
- Oxidation
- ATP formation
2
Q
Priming reactions
A
- Two high energy phosphates from 2 ATP molecules are added to 6 carbon molecule glucose
- produces 6 carbon molecule with 2 phosphates
3
Q
What does glycolysis begin with?
A
The addition of energy`
4
Q
Cleavage
A
- 6 carbon molecule with 2 phosphates is split in 2
- forms 2 3-carbon sugar phosphates
5
Q
Oxidation
A
- additional inorganic phosphate incorporated into each 3 carbon phosphate
- oxidation reaction converts the 2 sugar phosphates into intermediates that can transfer a phosphate to ADP to from ATP
- oxidation reactions also yield NADH
6
Q
ATP formation
A
- oxidation reaction converts the 2 sugar phosphates into intermediates that can transfer a phosphate to ADP to from ATP
- net energy yield of 2 ATP and 2 NADH
7
Q
What is the net yield of glycolysis
A
2 ATP
2 NADH
8
Q
substrate level phosphorylation
A
enzyme transfers inorganic phosphate from to ADP to for ATP
ex: PEP gives phosphate to ADP to make pyruvate and ATP
