2. Glycolysis- Important points, steps, regulation and energetics

3 irreversible steps
2 substrate level phosphorylation
3 regulatory enzymes
aerobic and anaerobic pathway
only source of energy for matured RBCs
important in muscular exercise
2 ATP produced in anaerobic glycolysis
7 ATP produced in aerobic glycolysis
Regulation is by
Insulin favors glycolysis
Glucagon represses glycolysis
ATP and citrate inhibit PFK allosterically
AMP and F2,6 bisphosphate activate PFK


spell correction- strenuous exercise
