Answer:
<em>The competitive inhibitor binds to the active site and prevents the substrate from binding there.</em>
Explanation:
The noncompetitive inhibitor binds to a different site on the enzyme; it doesn't block substrate binding, but it causes other changes in the enzyme so that it can no longer catalyze the reaction efficiently.
Answer:
Negative feedback mechanism may be defined as the system of the body in which the final output reduces the process and result in the less output. Negative feedback mechanism is important for the regulation of homeostasis.
The negative feedback mechanism maintains the constant body temperature. The change in body temperature is sensed by the receptors. The low body temperature initiates the hypothalamus to increase the physiological process. The blood vessels narrow, body start shivers and hormone stimulation increases body temperature. When the body temperature become normal, the hypothalamus will no longer be stimulated and stop its effect.
Answer:
In the electron transport chain, when the protons move down their concentration gradient, the electrons are transferred from one molecule to the other and energy is released.
Explanation:
During the rear stage of cell respiration or oxidative phosphorylation two processes are involved. Among which one is the electron transport proton gradient chain, in which protons are transferred from one to the other molecule.
In this process electron also releases energy to make an electrochemical gradient. In this chain oxygen accepts protons and chooses electron to produce water.
The answer is false. Cellular growth happens until the day of death.
