Biochemical Reaction Mechanisms

1. Mechanism of action of a-chymotrypsin

2. Glycolysis: metabolism of glucose

3. Biosynthesis of steroids from squalene

mechanism of action of a chymotrypsin

Mechanism of action ofa-chymotrypsin

(An enzyme that hydrolyzes peptides in the digestive system)

glycolysis

Glycolysis

Metabolism of glucose to form pyruvate and ATP

glycolysis converts glucose into two pyruvate molecules
Glycolysis converts glucose into two pyruvate molecules
  • …with the production of 2 ATPs (high energy storage in cells)
    • Isomerization of glucose to fructose
    • Formation of iminium ion; retro aldol to form two 3-carbon sugars (as phosphates)
    • Isomerization of dihydroxyacetone to glyceraldehyde (as phosphates)
    • Oxidation, isomerization, dehydration and dephosphorylation to form pyruvate and ATP
grading final exam
You may replace any of the 5 tests by an improved grade on that section of the Exam.

Only the higher grade counts.

You need not retake a section if you are happy with your grade on that test.

Everyone must take Section 6 (Ch 25, 26, 27 & 29) plus Section 7 (comprehensive; mostly synthesis)

Grading / Final Exam

Example:

Your (best) score on these seven sections plus

the sum of your gla scores determines your grade.
