Which of the following is false concerning the process known as cotransport?
A)Only neutral compounds such as sugars are transported.
B)More than one molecule or ion is moved through the cell membrane at one time.
C)ATP is not required by the transport protein.
D)Molecules can be moved against a concentration gradient.

Question

Quizplus · Accepted Answer

Cotransport, also known as secondary active transport, is the process by which two or more molecules or ions are transported across a cell membrane by a single transport protein, using the energy released by the movement of one solute down its concentration gradient to drive the uphill movement of another solute against its concentration gradient. Cotransport can occur with neutral compounds such as sugars, as well as with ions such as Na+ and H+. Therefore, option A is false. The other options are true statements about cotransport.
