Lecture #19: Cellular Respiration

Question 1

What is the equation for cellular respiration?

Answer 1

C6H12O6 + 6 O2 —-> 6 CO2 + 6 H2O + 32 ATP (energy)
- Extergonic process
6 O2 –> 6 H2O = reduction
C6H12O6 —> 6 CO2 = oxidation

Question 2

Glycolysis

Answer 2

Anarobic
- ancient pathway
Produces
- 2 ATP
- 2 NaDH
Occurs in cytosol

Question 3

Pyruvate –> Acetyl CoA

Answer 3

• Anarobic process
• Produces 2 NaDH

Question 4

Krebs Cycle

Answer 4

• Aerobic process
  Produces:
• 2 ATP
• 6 NaDH
• 2 FaDH2

Question 5

Electron transport chain

Answer 5

• Aerobic process
• Takes electrons from NaDH, FaDH2, to produce more ATP
  NaDH and FaDH2 donate e- to E.T.C
  E- is passed through chain and energy from e- is used to pump H+ from matrix across the inner membrane of mitochondrion
  Proton (H+) diffuse back through coupled channel - (ATP Synthase) to produce ATP

Question 6

Oxidative phosphorylation

Answer 6

ADP + P —> ATP
- (free P)
- receive more ATP this way

Question 7

Ions and chemical groups in Biol 1107

Answer 7

CH3 = methyl group
NH2 = Amine group
COOH = carboxyl group
PO4 = phosphate group
H+ = hydrogen ion (proton)
OH- = hydroxyl ion
Na+
K +
Ca 2+
Cl -
