Metabolic Pathways Flashcards
(9 cards)
1
Q
Glycolysis
A
Takes place in the cytosol, converts glucose into pyruvate with 10 enzyme-catalysed reactions
2
Q
Result of glycolysis
A
2 pyruvate, 2 ATP, 2 NADH
3
Q
Phosphorylation
A
Addition of a phosphate group
4
Q
Substrate-level phosphorylation
A
Enzyme-catalysed phosphorylation from donor ADP to form ATP
5
Q
Pyruvate oxidation
A
Occurs in mitochondrial matrix, pyruvate is oxidised to acetate and CO2 is released, nad+ is reduced to NADH, capturing energy
6
Q
Inputs of citric acid cycle
A
Acetal CoA, water, electron carriers (NAD+, FAD, GDP)
7
Q
Outputs of citric acid cycle
A
CO2, reduced electron carriers, ADP is converted to ATP
8
Q
Stages of oxidative phosphorylation
A
Electron transport, chemiosmosis
9
Q
Metabolism of glucose
A
Produces free energy then traps it in ATP
