Textbook Question
Chapter 13, Problem 3RE
REFLECT AND APPLY When proteins are separated using native gel electrophoresis, size, shape, and charge control their rate of migration on the gel. Why does DNA separate based on size, and why do we not worry much about shape or charge?

Question: what is the KM and Vm and the nature of inhibition
1. Estimate the concentration of an enzyme within a living cell. Assume that:
(a): fresh tissue is 80% water and all of it is intracellular
(b): the total soluble protein represents 15% of the weight
(c): all the soluble proteins are enzymes
(d): the average molecular weight of the proteins is 150,000
(E): about 100 different enzymes are present
