<h2>PNS and SNS</h2>

Explanation:

Parasympathetic nervous  system (PNS)  

  • In the event that the blood pressure is increased because of any explanation, it is detected by the baroreceptor system
  • The baroreceptor reflex invigorates is the part of the parasympathetic nervous system
  • The PSNS causes reflation of veins, decreasing total peripheral resistance. It also decrease the heart rate

Sympathetic nervous system  (SNS)  

  • Heart rate and blood volume are regulated  by the interrelated activities of the sympathetic nervous system (SNS) and the renin-angiotensin-aldosterone system (RAAS)
  • The SNS is improperly dynamic in obesity and <em>hypertension</em> and plays a causal or permissive role in all types of chronic hypertension

Answer:

Explanation:

a) Ph that is below or above the optimal range will result in enzyme activity loss.  if the pH changes above or below optimum range affects the charges that is present on the amino acid molecules. Amino acids presrnt in the active  site of enzymes that attracted each other may no longer continue to be attracted. Again, the shape of the active site of the enzyme changes due to the substrate binding will be affected. conclusively, we can say that the enzymes are denatured.

b) researchers are most likely to use a negative control when measuring the rate of reaction in the presence of each organisms. enolase is controlled  with no enzyme.

c) c) Since the C.aurantiacus grows best at 550C , we can say that the enzymes that they produce must be at this temperature and so they must be sensitive to this temperature ; hence they would show more activity at 550C temperature.

How does the structure of a cell membrane affect its permeability?
Genrish500 [490]
The phospholipids are tightly packed together, and the membrane has a hydrophobic interior. This structure causes the membrane to be selectively permeable. A membrane that has selective permeability allows only substances meeting certain criteria to pass through it unaided.
