If a poison mimics glucose, what is likely to happen (at the metabolic level) to someone
who ingests this poison?
8.
What are the end products of glycolysis?
9.

10.
Where does oxidative phosphorylation take place? What is oxidative phosphorylation?
12.
Which has more energy: One molecule of glucose or 2 molecules of pyruvate? Why?
13.
When water is formed during oxidative phosphorylation, where do the oxygen atoms
come from?
14.
When a muscle is deprived of oxygen, what do the cells do with the pyruvate? What
