Chapter 7: Cellular Respiration and Fermentation
Overview of Cellular Respiration
make ATP, NADH, and
FADH2.
Process by which living cells obtain energy
from organic molecules.
Aerobic respiration uses oxygen.
Glucose metabolism
C6H12O6 + 6O2 → 6CO2 + 6H2O
1- Glycolysis
Energy liberation:
Two glyceraldehyde-3-phosphate molecules broken down into two pyruvate molecules.
Cleavage:
6 carbon molecule broken into two 3 carbon molecules of glyceraldehyde-3-phosphate (G3P)
Energy investment:
2 ATP hydrolyzed to create fructose-1,6 bisphosphate.
Products: 2 pyruvates, 2ATP, 2NADH
Place: Cytoplasm
Anaerobic Respiration and Fermentation
Anaerobic Respiration: Use substance other than O2 as final electron acceptor in electron transport chain.
Fermentation: Produce ATP only via substrate-level
phosphorylation.
2- Breakdown of Pyruvate
Products: 2CO2, 2Acetyl, 2NADH
Place: Mitochondrial matrix
3- Citric Acid Cycle
Products: 2ATP, 4CO2, 6NADH, 2FADH
Place: Mitochondrial Matrix
4- Oxidative Phosphorylation
High energy electrons removed from NADH
and FADH2 to make ATP.
products: 30- 34 ATP
Place: Inner mitochondrial membrane
