Glycolysis Practice Problems Reading Chapter 16 End of the chapter questions (pp. 473-474): 3, 4, 8, 9, 10, 15, and 20 Then try these: 1. Glucose is the primary metabolic fuel of the brain. Brain hexokinase has a K M is 0.05 mM, while the circulating blood glucose concentration is 5 mM. What is the advantage of this low K M ? 2. Yeast strains with mutations in the gene encoding phosphofructokinase cannot grow on media where glucose is the sole carbon source, but can grow on media where glycerol is the sole carbon source. Use your knowledge of glycolysis to explain this observation?

Unformatted text preview: 3. Explain why glycolysis can occur under aerobic or anaerobic conditions. 4. In the glycolytic pathway, be able to identify: Steps where the input of ATP is required Steps where ATP is synthesized by substrate-level phosphorylation Step where NAD+ is reduced to NADH How NADH is oxidized back to NAD+ in muscle, in some yeast, and under aerobic conditions Irreversible reactions (under normal cellular condtions) Regulated enzymes...
