Question

Which of the following is true of transporter proteins?

A. Transport of solute requires binding of the solute by the protein
B. Transporters can be gated by membrane potential or mechanical stress
C. Transporters are primarily for passage of ions through a membrane
D. All of the above are true.

Answer 1

Transporter proteins are involved in the facilitated diffusion of molecules across the cell membrane. They can be either carrier proteins or channel proteins. Transporters can be gated by membrane potential or mechanical stress.

Step-by-step explanation:

Transporter proteins are involved in the facilitated diffusion of molecules across the cell membrane. They can be either carrier proteins or channel proteins.

Carrier proteins require binding of the solute to transport it across the membrane, while channel proteins create pores for ions to pass through. Transporters can be gated by membrane potential or mechanical stress.
