Cellular Respiration

Question 1

Glycolysis
Location
Input/Output

Answer 1

Cytoplasm of Mitochondria

Input:
1 6 carbon glucose molecule
2 ATP
2 NAD+

Output:
2 Pyruvate
4 ATP
2 NADH

Question 2

Glycolysis Summary
Summarise
Energy/ATP input?
Aerobic or Anaerobic?

Answer 2

Glucose Molecule broken down: phosphorylation (adding phosphate groups)
cleaving (removing phosphate groups)
Original 6-carbon glucose molecule = 2 Pyruvates/Pyruvic Acid

Requires energy from ATP input

Anaerobic: does not require oxygen

Question 3

Pyruvate Oxidation/
Pyruvate Decarboxylation

Answer 3

Process converts Pyruvate into Acetyl Co-A to enter Citric Acid Cycle

Question 4

Citric Acid/Krebs Cycle
Location
Input/Output

Answer 4

Matrix of Mitochondria

Input:
2 Acetyl Co-A
NAD
FAD
2 ADP

Output:
CO2
NADH
FADH2
2 ATP

Question 5

Citric Acid/Krebs Cycle Summary
Summarise
Energy/ATP input?
Aerobic or Anaerobic?

Answer 5

Each Pyruvate enters the CAC/Krebs Cycle and undergoes series of reactions that produce CO2 and coenzymes (NADH and FADH2) and 2 ATP

No direct energy/ATP input

Aerobic: requires oxygen to continue

Question 6

Cellular Respiration
Coenzymes and Function

Answer 6

NAD+ and FAD+
become
NADH and FADH2

Collect Hydrogen atoms during Glycolysis and Citric Acid Cycle and deliver them to Electron Transport Chain
