Cell-wall inhibiting antimicrobial drugs be less effective on gram-negative bacteria compared to gram-positive bacteria because the outer membrane of the gram-negative bacteria inhibits penetration of the drug and the peptidoglycan found in gram-positive bacteria is structurally different from that in gram-negative bacteria.
Answer: Option B & C
<u>Explanation:</u>
Antimicrobial drugs are induced into a body to act on that particular selective bacterium which causes disease. When antimicrobial drugs are injected they act efficiently on the gram positive bacteria inhibiting the proliferation of the cells by acting on the cell wall so that cell multiplication doesn’t happen.
On the other hand it is hard to act on the gram-negative bacteria as it has a cell membrane that inhibits drug penetration into it. Both cell walls contain peptidoglycan but in the gram-positive is more assembled and layered while in the gram-negative it is just a thin layer. As gram-positive is thick layered it provides place for another molecule to attach to it but the thin layer in gram-negative inhibits it.
The configuration is a concept that is related to the order (poition) by which different substituents linked to the same central atom, in the case of amino acids, around the central carbon atom. So, amino acids can be divided in two groups, L- and D- forms, analogous to left-handed and right-handed configurations.
On the other hand, protein folding (folded structure of peptides) is the physical process by which a protein chain acquires its conformation (3D structure) that is usually biologically functional.
Natural gas
explanation:
solar power, coal, and petroleum are used to power things (i.e. produce electricity)
Answer: Ectotherms depend on external heat sources. Their body temperature changes with the temperature of the environment. Endotherms generated heat internally to maintain body temperature.
