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.

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
