Question

The feedback mechanism in cells means:

• A. Cells are independent of each other in their functioning
• B. Cells receive feedback from nature how to behave
• C. Cells control their biochemical pathways where intermediate products of a pathway act as an inhibitor of the reaction
• D. One cells controls the behavior of other cell by signaling

Answer 1

The correct option is C

Cells control their biochemical pathways where intermediate products of a pathway act as an inhibitor of the reaction

Feedback occurs when outputs of a system are routed back as inputs, as part of a chain of cause-and-effect that forms a circuit or loop. This is one of the most common ways by which cells control their biochemical cycles. The accumulation of the products produced by a reaction inhibits the reaction. This slows down the rate of the reaction. This is an example of the feedback mechanism.
