Question

multiple choice question
which of the following describes proteins that aid in the movement of materials across a membrane?

channels and carriers
flippases
adhesins
integrases

Explanation:

• Channels form pores for passive transport of materials across cell membranes.
• Carriers bind to substances and transport them (passive or active) across membranes.
• Flippases move lipids within the membrane bilayer, not materials across it.
• Adhesins enable cell adhesion, not membrane transport.
• Integrases integrate genetic material into genomes, unrelated to membrane transport.

Answer:

Channels and carriers
