BIO 103-01 How Cells Release Energy and Aerobic Respiration

Aerobic Respiration

Respiration that requires oxygen

Glycolysis

first stage of aerobic respiration; the breakdown of glucose by enzymes, releasing energy and pyruvic acid.

Acetyl CoA Formation

second stage of aerobic respiration; in the inner compartment of the mitochondrian, enzymes split pyruvate, forming acetyl CoA and CO2 (which diffuses out of the cell)

Krebs Cycle

second stage of aerobic respiration; the break down of acetyl CoA into 2 CO2; Oxoloacetate is used and regenerated - cyclic pathway

Electron Transfer Phosphorylation

Third stage of aerobic respiration that occurs in the mitochondria; Results in attachment of phosphate to ADP to form ATP; Requires molecular oxygen - accepts electron at last electron transfer step

How many carbons are there in each compound at the end of glycolysis?

3

How many ATP are produced by electron transfer phosphorylation?

32
