Answer:
Polymyxin because, it inserts into the cell membrane and disrupts homeostasis.
Explanation:
Antimicrobial effect reacts with the cell membrane of the gram negative bacteria and causes disruption in their cell membrane by creating pores.
The cell membrane of bacteria release endotoxin for creating defense mechanism.
But the effect of certain antimicrobial peptide disrupt the effect of membrane by releasing electrostatic interaction and creates membrane pores.
The interaction between the microbial peptide and the cell membrane causes disruption of the cell.
Thus polymyxin is used to treat against the gram negative bacteria as they breaks the cell membrane of the bacteria.
Answer:
Fasting can definitely raise blood glucose. This is due to the effect of insulin falling and the rising counter-regulatory hormones including increased sympathetic tone, noradrenaline, cortisol and growth hormone, in addition to glucagon. These all have the effect of pushing glucose from liver storage into the blood. This is normal. If you are not eating, you want to use some stored glucose. The question is this – if you are not eating, and your blood glucose went up, where did that glucose come from? It can only have come from your own body (liver). So, it’s a natural phenomenon, and the fasting now allows your body to use some of the glucose for energy.
