Why is it important that the phospholipid has both hydrophilic and hydrophobic
regions?
Answer:
The formation of a micelle is a response to the amphipathic nature of fatty acids, meaning that they contain both hydrophilic and hydrophobic regions.
Explanation:
Biological membranes remain fluid because of the unsaturated hydrophobic tails, which prevent phospholipid molecules from packing together and forming a solid.

in terms of structure, how do channel proteins differ from carrier proteins?
Answer:
Moreover, carrier proteins can carry out both active and passive transportation of solutes, whereas channel proteins bring about passive transport only. Both carrier proteins and channels proteins also differ in their chemical composition - whilst the former are glycoproteins, the latter are lipoproteins.
Explanation:
hope this helped you if it did please mark brainiest
Carrier proteins can carry out both active and passive transportation of solutes, whereas channel proteins bring about passive transport only.
What are the functions of carrier proteins?Carrier protein is a type of cell membrane protein involved in facilitated diffusion and active transport of substances out of or into the cell. Carrier proteins are responsible for the diffusion of sugars, amino acids, and nucleosides.
Moreover, carrier proteins bind specific solutes and transfer them across the lipid bilayer by undergoing conformational changes that expose the solute-binding site sequentially on one side of the membrane and then on the other.
Membrane carrier proteins are important transmembrane polypeptide molecules which facilitate the movement of charged and polar molecules and ions across the lipid bilayer structure of the cell membranes.

Protein pumps are efficient because they
(Plz help)
In reference to the options listed in the image, we can say that protein pumps are efficient because they can move two types of molecules, which makes option B correct.
A protein pump is a kind of protein, often found in the cell membrane, that has the capability to pump specific substances in and out of the cell. Most of the processes that happen at the cellular level are naturally optimized for efficiency, even when the process consumes energy, as is the case with the protein pump.
The reason that the protein pump is considered efficient lies in how it uses the energy. Despite being an active process that consumes ATP to function, protein pumps are considered efficient because they can move two types of molecules at the same time, using the same molecule of ATP. This allows the cell to get more done for the same amount of energy.
