Covalent modification Study guides, Class notes & Summaries

The three domains Bacteria, Archaea, Eukarya Negative feedback versus positive feedback Feedback regulation is when the output or product of a process regulates that very process. An example of negative feedback is sweating, insulin producing cells. An example of positive feedback is blood clotting.
