Feedback allows the product of a pathway to control the switch. Sometimes referred to as a “negative feedback loop”, negative feedback occurs when the product of a pathway turns the biochemical pathway off. Positive feedback, the opposite of negative feedback, is found in other biological pathways in which the product increases the pathway. Below are examples of negative feedback.
