Exam 11: Cellular Energetics

The four stages of glucose oxidation are listed below.Place them in the correct order. I. pyruvate oxidation to CO₂ in the mitochondrion via a 2-carbon acetyl CoA intermediate (citric acid cycle) II. electron transport to generate a proton motive force III. conversion in the cytosol of one 6-carbon glucose molecule to two 3-carbon pyruvate molecules (pyruvate)(glycolysis) IV. ATP synthesis in the mitochondrion (oxidative phosphorylation)

Question 2

Correct Answer:

Verified

Lactic acid is secreted from muscle cells into the bloodstream.Some is taken up from the bloodstream by the liver,where it is either reoxidized to pyruvate then metabolized to generate energy and CO₂ or it is converted back to glucose and stored as glycogen in the liver.Some of the lactic acid is metabolized to CO₂ in the heart.
