Solution

The first enzyme to be immobilized by the adsorption method was invertase. This technique involves attaching enzymes to solid supports to enhance their stability and reusability in various applications, particularly in biochemical processes and industrial productions. Invertase, which catalyzes the hydrolysis of sucrose into glucose and fructose, was one of the earliest enzymes studied for immobilization. The adsorption method is popular due to its simplicity and effectiveness, allowing the enzyme to retain activity while being fixed on a support, thereby facilitating separation from the reaction mixture. Other enzymes like protease, glucose isomerase, and amylase have also been immobilized but not as the first instance.

Final Answer

The first enzyme to be immobilized by the adsorption method was c) Invertase.
