The impermeability of cell plasma membranes is a major barrier to using drugs to kill tumor cells or affect cells transgenically. cpps are peptides that were discovered to have the ability to transport themselves (and even attached cargo) into cells. how they get into cells is still a mystery, but cpps all have multiple positively charged groups. which of the following membrane components are they most likely to be interacting with?
a. phospholipid heads
b. phospholipid tails
c. intrinsic membrane proteins
d. cholesterol

B. phospholipid heads

Explanation:

Phospholipid heads contain phosphate groups which are negatively. The positively charged CPPs would be attracted by the phospholipid heads via ion-ion interactions.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
