Flashcards in 7. Cellular Respiration Deck (10):
1

Substrate-level Phosphorylation

Hydrolysis of a phosphorylated organic molecule + the addition of a phosphate group to ADP --> forms ATP

2

Oxidative Phosphorylation

Chemical energy of organic molecules transferred to electron carriers, transports electrons released to the respiratory e transport chain to final e acceptor (oxygen if aerobic)

3

Oxidation

molecule loses electron

4

Reduction

molecule gains electron
more chemical energy than oxidised form

5

Cellular respiration in Bacteria

Takes place in cytoplasm and plasma membrane

6

Passing electrons

can only passed from molecules with higher to lower Potential Energies

7

Glycolysis

Glucose is partially broken down to make pyruvate and energy is transferred to ATP and reduced electron carriers
Takes place in Cytoplasm
Anaerobic

8

Pyruvate Oxidation

Pyruvate is oxidised to acetyl-coA, producing reduced electron carriers and releasing CO2.
Takes place in Mitochondria

9

Where is H+ conc. the highest in e- transport chain?

Intermembrane Space

10

Activators and Inhibitors of PFK

Activators: ADP and AMP
Inhibitors: Citrate and ATP (when high enough volumes)
