Name the causative agent of choleraIn the first stage of glycolysis, fructose-1,6-bisphosphate is
cleaved to form glyceraldehyde-3-phosphate and dihydroxy-
acetone phosphate. The latter molecule can then be con-
verted to glyceraldehyde-3-phosphate. Illustrate the
mechanisms whereby these reactions occur.
During glycolysis, 112 molecules of pyruvic acid (PVA) were formed. How many glucose molecules were broken down and how many ATP molecules are formed after complete oxidation of glucose in eukaryotic cells? Explain the answer.
Compare and contrast the structure and function of various types of microscopes
List and discuss, in your own words, the four key parameters of the Michaelis–Menten Equation. Your response must clearly outline the definition of each of the parameters,and its application to enzyme activity/substrate interaction affinity/catalytic efficiency.
