use the output of a system to signal a change in input so that a system response can be stabilized or amplified

• homeostasis

• physiology

• amplification

• feedback mechanism

the output (or product) of a system intensifies the response

• negative feedback loop

• positive feedback loop

• neutral feedback loop

• homeostasis

A special category of proteins that catalyze (speed up) chemical reactions

• amino acids

• chromosomes

• inhibitors

• enzymes

Enzymes are used to regulate metabolism. Cells can regulate these enzyme by

• turn synthesis of enzymes on or off

• chemical inhibitors can bind to enzymes and slow them

• environment (pH, temp, etc.)

• all of these
