Vitamins and Coenzymes

A class of organic compounds needed in the human body for normal activities is known as vitamins. They are characterized into two parts depending upon their solubility in water. They can act as coenzymes, cofactors, or prosthetic groups for enzymes.

Question

Esterase hydrolyzes ester bonds. For simplicity, only the amino acids whose side-chains
interact with the substrate are shown. Each circled interaction is important for the binding
of the substrate to the enzyme.

Full activity of esterase is observed at 37°C and a pH of 7.4. You isolate the active form of
esterase, subject it to a high salt (high sodium chloride) concentration and show that it cannot bind
the substrate. You then return the sample to the original conditions and measure the substrate
binding ability of the esterase again.
Would the esterase bind to its substrate when returned to the pretreatment conditions
(Yes/No)? Explain.

According to the following graph, the activity of the enzyme decreases more sharply at high temperature than at low temperature. What are the reasons for this observation? Enzyme activity Optimum temperature Temperature, °C I. As temperature is increased, the substrate binding slowly becomes poorer. II. As temperature is decreased, the enzyme moves more slowly and so reacts more slowly. III. At higher temperatures, the enzyme is denatured and stops working entirely. IV. Temperature has no effect on enzyme activity. ○ I only O IV only I and III O II and III
