Question

Give the location, whether it is anaerobic or aerobic and the net production, (Per Glucose) of the listed compounds:

a. Glycolysis: ATP, NADH, Pyruvic Acid

b. Prep Step ( Intermediate Stage): ATP, CO2, NADH

c. Krebs Cycle: ATP, CO2, NADH,FADH2

d. Oxidative Phosphorylation: ATP

Answer 1

a. Glycolysis:

Location: Cytosol

Anaerobic (doesn't require Oxygen)

ATP: Net 2 ATP molecules per glucose

NADH: 2 NADH molecules per glucose

Pyruvic Acid: 2 Pyruvic acid molecules per glucose

b. Prep Step ( Intermediate Stage):

Location: Mitochondria

Aerobic (occurs in presence of oxygen)

ATP: 0

CO2:    2 CO2 molecules per glucose

NADH:   2 NADH molecules per glucose

c. Krebs Cycle:

Location: Mitochondria

Aerobic (occurs in presence of oxygen)

ATP   : 2 ATP (or GTP) molecules per glucose

CO2 : 4 CO2 molecules per glucose

NADH : 6 NADH molecules per glucose

FADH2 : 2 FADH2 molecules per glucose

d. Oxidative Phosphorylation:

Location: Mitochondria

Aerobic (directly involves oxygen at the end of electron transport chain)

ATP : 28 ATP (2.5 x 10 = 25 ATP for NADH,   1.5 x 2 = 3 ATP for FADH2)
