Given the following biochemical pathway, in which the letters represent chemical substances in the pathway and numbers represent enzymes that catalyze the reactions represented by the arrows. Additionally, substance D is required for the proper growth of a cell: A -- 1 --> B -- 2 --> C -- 3 --> D If a cell has a mutation that prevents enzyme

Intermediate Product Accumulation

Explanation:

If one of the crucial enzyme say B is mutated in the process of normal product formation, then the reaction will not proceed further from that point and accumulation of an intermediate product in the cell takes place. The mutation in the enzyme could be environmental or genetic but it will surely alter the enzyme functioning. In the end, the damage malfunctioning cell will be removed using the process of apoptosis.

what's the question ?

genetic variation will increase because of a new habitat and food source.
