Question

fill in the blank question
many substances that are repelled by the hydrophobic interior of the lipid bilayer can readily diffuse across the plasma membrane with the help of specific
proteins or
proteins. these transporter proteins are typically transmembrane proteins.
need help? review these concept resources.

Explanation:

To solve this, we recall the types of membrane transport proteins. Substances repelled by the lipid bilayer (hydrophilic or polar) use channel proteins (form pores for passive transport) or carrier proteins (bind and transport substances, can be passive or active) to cross the plasma membrane. These are transmembrane proteins facilitating diffusion for non - lipid - soluble substances.

Answer:

The first blank should be filled with "channel" and the second blank should be filled with "carrier".
