Answer:
<h2>They are classified on the basis of their cell wall composition and as well as by the reaction to the Gram stain test.
</h2>
Explanation:
Most bacteria are classified into two main categories
i) Gram positive bacteria and ,
ii) Gram negative bacteria.
They are classified on the basis of their cell wall composition and as well as by the reaction to the Gram stain test.
Gram positive bacteria's characteristics
ii) they have cell walls composed mostly of peptidoglycan.
i) stain purple after Gram staining.
Gram negative bacteria's characteristics.
i) they have cell wall only a thin layer of peptidoglycan and an outer membrane with a lipopolysaccharide component.
ii) stain red or pink after Gram staining.
A patient with sickle cell crisis will most likely complain of severe pain.
A patient with sickle cell disease have an abnormal amino acid composition of hemoglobin, leading to a comformational change to insoluble proteins whenever the red blood cell is deoxygenated; this leads to a change in shape from biconcave to sickle shaped. In sickle cell crisis, the abnormal RBC clump together (easily, because of their shape) then obstruct small blood vessels in the extremities and other organs, causing severe pain.
Chemical energy is used to pump protons through a proton pump, creating a high concentration of protons ( H+ ) inside the thylakoid disk. ATPase has a channel that allows for the facilitated diffusion of protons back in through the membrane. this activates ATPase, which in turn catalyzes the formation of ATP.
