Peripheral membrane proteins (select one):

A) penetrate deeply into the lipid bilayer.
B) are usually denatured when released from membranes.
C) can be released from membranes only by detergent treatment.
D) are generally noncovalently bound to membrane lipids.

Peripheral membrane proteins (select one):

D) are generally noncovalently bound to membrane lipids.

Explanation:

Peripheral membrane proteins are membrane protenis that adhere only temporarily. These don't penetrate deeply into the lipid bilayer, just penetrate the peripheral regions.  Also they are bound to either face of the membrane by noncovalent interactions. There are many different categories of peripheral membrane proteins: Membrane-targeting domains; transporters of small hydrophobic molecules ; electron carriers ; Polypeptide hormones, toxins, and antimicrobial peptides; structural domains; enzymes.

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
