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
