Answer:
Proteins in a membrane are C. Both answer choice is true.
Explanation:
Membranes have different types of proteins. <em>Peripheral proteins are the ones that are placed on the inside suface held in place by the cytoskeleton. Integral proteins are the ones that are embedded in the membrane and protrude from either surfaces of the bilayer. </em>These integral proteins also can be carrier proteins, which facilitate passage of molecules through the membrane
; enzymatic proteins, whichcatalyze a specific reaction or they can recognize pathogens, baing cell recognition proteins. In the membrane we can find aquaporins too, which are membrane channel proteins that enable water to cross a membrane.
A. Contagious fatal virus
Answer:
Catabolic
Explanation:
It is catabolic becaus it is a metabolic pathway that involves the process of breaking down large complex molecules in the living cells into smaller molecules thereby releasing energy.
Examples of these metabolic pathway are the break down of fat in adipose tissues into fatty acids, glycolysis, citric acid cycle, oxidative deamination of neurotransmitters e.t.c.
Answer:
The correct answer will be option a and b.
Explanation:
The food is digested and absorbed in the small intestine, a long folded tube which lengths about 20 ft or 6m.
The small intestine increases the surface area for food absorption as they have circular folding as well as the finger-like projections called villi and microvilli in the lumen of the intestine. These villi help in absorption of the nutrients from the intestine.
Thus, option a and b are the correct options.
