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.

Bumek [7]

Answer:

A. Cellular respiration

C. Photosynthesis

Explanation:

There are two main processes occurs in the carbon cycle i.e. cellular respiration and photosynthesis. Plants absorb carbondioxide gas from the atmosphere through small openings called stomata. The carbondioxide enters the leaves and combine with water produces glucose and oxygen. Glucose is stored in different parts of plant whereas some oxygen is used by the plant and the remaining oxygen is releases in the atmosphere while on the other hand, in cellular respiration, glucose is broken down to produce energy in the form of ATP, carbondioxide gas and water.
