Answer: Nervous system.
Explanation:
Nervous system is the system in the body that consists of nerves,cells that coordinates action and sensory information and transmit nerve impulses between the body and the brain. In the body, Ghrelin is an hormone or chemical produced in the stomach. This stimulate hunger by acting on neurons in the hypothalamus which make the nerve cells that cause hunger to increase in their activity and reduce hunger inhibiting cells. The hypothalamus produce two proteins that cause hunger: neuropeptide Y (NPY) and agouti-related peptide (AGRP. This create a signals and it is send to the brain. The brain interprete it as hunger and send the signal to the hypothalamus which then influence eating behavior.
Skeletal muscles are one of the three muscle types they are a form of striated muscle tissue.
Answer;
The enzyme structure begins to break down
intermolecular bonds are broken
enzyme molecules gain kinetic energy.
Explanation;
Enzymes are proteins that play an important function in the body of catalyzing reactions in the body.
Enzymes work best at optimum temperature; low temperature lower than optimum temperatures deactivates them and higher temperature denatures them.
The shape of an enzyme depends on its temperature; when they get too warm they get loose, and at very low temperatures they get too tight. At optimum temperature or at the right temperature then they are just at the right shape and the chemical reactions they catalyze will be at optimal rate.
During prophase, the parent cell chromosomes — which were duplicated during S phase — condense and become thousands of times more compact than they were during interphase. ... Cohesin forms rings that hold the sister chromatids together, whereas condensin forms rings that coil the chromosomes into highly compact forms.
