Which of these is an example of negative feedback? which of these is an example of negative feedback? the end product of a reaction sequence has no effect on the reaction sequence. the end product of a reaction sequence shuts down the reaction sequence. the first enzyme in a reaction sequence makes the free energy change of the reaction more negative. the end product of a reaction sequence speeds up the reaction sequence. the first enzyme in a reaction sequence lowers the activation energy of the reaction.

This statement is an example of a negative feedback: The first enzyme in a reaction sequence lowers the activation energy of the reaction.

In Biology, negative feedback always results in a reaction that has a decreased function. This type of feedback occurs as a response to a particular kind of stimulus.

Negative feedback is necessary because it lessens the overall output of a particular system; as this continually happens, the system begins to stabilize. In Biology, this is what any organic material always seeks to achieve, a level of stabilization known as homeostasis or equilibrium.
