An important aspect of transport by facilitated transporters and pumps is ________.
A)conformational shifts
B)rigidity
C)softness
D)$\alpha$-helix secondary structure
E)$\beta$-pleated sheet secondary structure

Question

Quizplus · Accepted Answer

Facilitated transporters and pumps undergo conformational shifts to transport molecules across a membrane. These shifts allow for ligand binding and changes in protein shape that move the molecule from one side of the membrane to the other. Rigidity or softness of the transporter would not allow for this movement, and the F1F1F1S1F1F1F10-helix and F1F1F1S1F1F1F10-pleated sheet structures are not relevant to facilitated transport or pumps.
