Why does the number of phagocytes and lymphocytes in the body increase during an infection?

1 answer:

7 0

A. More phagocytes and lymphocytes are needed to fight the infection.

Phagocytes and lymphocytes are basically the white blood cells in our body that are used to fight off infections and diseases. Naturally, your body would want to create more to close up a wound if you got a simple cut, but to have that become infected or for you to generally have an infection, there's going to be a larger demand for them. Diseases and infections bring bacteria and foreign invaders into your body, so you will want more phagocytes and lymphocytes to fight them all off and return back to your health.

Under physiological conditions, peptide bond formation and degradation both require enzymes, but only formation requires couplin

Answer:

thermodynamically unstable but kinetically stable.

Explanation:

The complete question is as follows:

Under physiological conditions, peptide bond formation and degradation both require enzymes, but only formation requires coupling to GTP hydrolysis. Based on this information, peptide bonds under physiological conditions are:

A. both thermodynamically and kinetically stable.

B.thermodynamically unstable but kinetically stable.

C.thermodynamically stable but kinetically unstable.

D. both thermodynamically and kinetically unstable.

The term thermodynamically unstable refers to the fact that the peptide bonds are prone to breakage under physiological conditions.
The reason why one can conclude the thermodynamic instability of the peptide bonds under physiological condition is that there is a need for a source of energy i.e. GTP hydrolysis for the formation of the peptide bond.
The fact that the breakage of peptide does not require any input of energy but the only formation does confirms the fact that under physiological conditions they are thermodynamically unstable.
Even though they are thermodynamically unstable, they are kinetically stable because both the formation and degradation require enzymes.
The function of enzymes is to decrease the activation energy and hence, increase the rate of reaction. This means that if the enzymes are absent the rate of breakage of peptide bonds would be really slow this points out to the fact that they are kinetically stable under physiological conditions.

Answer: C

Explanation: Instead of doing all of the experiments by yourself, you should ask other scientists for help, If you don’t, you would never know if they might get different results than you.
