Adenosine triphosphate (ATP) is the primary source of energy used by cells to do work. Most organisms produce ATP through a pathway known as cellular respiration, which involves the conversion of food energy (like sugars) into ATP. When excess levels of ATP are present in cells, they often interact with the enzymes involved in cellular respiration to prevent the conversion of food energy into ATP thus allow that food energy to be stored (often as fat). What type of feedback is this?

When a blood vessel is damaged, platelets release a variety of chemicals that attract other platelets and blood cells to the site of damage. As more platelets enter the damaged area, they release even more of these chemicals which, in turn, attract even more blood cells to eventually form a platelet plug. This continues until the damaged vessel is sealed. What type of feedback is this?
