BIOMOLECULES AND ENZYMES

Detailed explanation-1: -An effector is the component in a feedback system that causes a change to reverse the situation and return the value to the normal range. In a negative feedback loop, a stimulus-a deviation from a set point-is resisted through a physiological process that returns the body to homeostasis.

Detailed explanation-2: -Hint: Remember, a positive feedback loop will continue the process in its original direction. A negative feedback loop will work to counteract the stimulus to maintain a set point.

Detailed explanation-3: -Negative feedback is defined as a decrease in function in response to a stimulus. In negative feedback, an output of a particular system or reaction is decreased. Positive feedback, is an increase in function in response to a stimulus.

Detailed explanation-4: -negative feedback loops, in which a change in a given direction causes change in the opposite direction. For example, an increase in the concentration of a substance causes feedback that ultimately causes the concentration of the substance to decrease.

Detailed explanation-5: -A negative feedback loop occurs in biology when the product of a reaction leads to a decrease in that reaction. In this way, a negative feedback loop brings a system closer to a target of stability or homeostasis.
