# ATP produced by glycolysis?

2

Type of phosphorylation used in glycolysis?

Substrate level

Where does the transition step occur?

Mitochondrial matrix

Reactants of transition step?

Pyruvate

Products of transition step?

CO2, NADH, acetyl CoA

# ATP produced by the transition step?

0

Where does Kreb’s cycle occur?

Mitochondrial matrix

Reactants of kreb’s cycle?

Acetyl CoA

Products of kreb’s cycle?

CO2, ATP, NADH, FADH2

# ATP produced by kreb’s cycle?

2

Type of phosphorylation used by kreb’s cycle?

Substrate level

Where does the ETC occur?

Inner mitochondrial membrane

Reactants of ETC?

NADH, FADH2, O2

Products of ETC?

H2O, ATP, (NAD+ and FAD recycled)

# ATP procuded by ETC?

~32

Type of phosphorylation in ETC?

Oxidative phosphorylation

Anaerobic respiration or fermentation produces how many ATP?

2 per glucose from glycolysis

Alcoholic fermentation

Produces ethanol, CO2, and 2 ATP. Pyruvate releases CO2 and form acetylaldehyde → reduced by NADH to form ethanol

Lactic acid fermentation

Produces lactate and 2 ATPs. Pyruvate is reduced by NADH to form lactate (NAD+ can be reused)
