A student is conducting an experiment in which he adds an inhibitor to an enzyme-catalyzed reaction that contains alkaline phosp

hatase. When the student first adds the inhibitor, the reaction rate decreases, however, he can return the reaction rate to normal by adding a large quantity of substrate. What type of inhibitor is the student using, non-competitive or competitive?

Answer:

competitive

Explanation:

An inhibitor is a substance that hinders the action of an enzyme. An inhibitor may be competitive or non competitive.

A competitive inhibitor is an inhibitor that is very similar to the substrate hence it binds to the enzyme instead of the substrate. A noncompetitive inhibitor binds to a site that is different from the active site. This site is called an allosteric site.

If we look at the experiment described in the question, the reaction rate decreases upon addition of the inhibitor. This effect is reversed by adding a large quantity of substrate.

The implication of this observation is that the enzyme and the inhibitor compete for the active site on the substrate.

Hence the inhibitor is a competitive inhibitor.

(b) The CPU is responsible for processing instructions.
Yakvenalex [24]

Answer:

The answer to this question is given below in the explanation section.

Explanation:

The CPU is responsible for processing instruction. CPU instruction processing goes through three stages. Fetch, Decode, and Execute.

When the program runs,  program code is copied from secondary storage into main memory. CPU's program counter set to the first instruction of the program stored in memory where the program starts executing.

When a program is being executed, it goes through fetch-decode-cycle. which repeats over and over again until reaching the STOP instruction.

The processor check which next instruction to be executed, then the processor fetches that instruction value from the memory location.  once the instruction being fetched it gets decoded and executed. This instruction processing cycle repeating until the CPU finds a stop instruction.
