Question

water diffuses through plasma membrane channels called
proteins
substrates
carriers
aquaporins
question 39 (1 point)

Explanation:

Water diffuses through specialized plasma - membrane channels called aquaporins. These are integral membrane proteins that form pores for water molecules to pass through. Proteins is a general term and not the specific channel for water diffusion. Substrates are substances on which enzymes act and are not related to water - diffusion channels. Carriers are used for facilitated diffusion of other substances, not specifically for water in the context of these channels.

Answer:

D. Aquaporins
