Question

Which of the following does not involve molecules moving across cell membranes?

A. Osmosis

B. Facilitated diffusion

C. Active transport

D. Induced fit

Answer 1

The correct answer is D. Induced fit does not involve molecules moving across cell membranes.

Step-by-step explanation:

The correct answer is D. Induced fit does not involve molecules moving across cell membranes.

Osmosis is the movement of water molecules across a cell membrane. Facilitated diffusion is the movement of molecules across a cell membrane with the help of transport proteins. Active transport is the movement of molecules across a cell membrane against the concentration gradient, requiring energy. On the other hand, induced fit refers to the change in the shape of an enzyme when it binds to a substrate, and it does not involve the movement of molecules across cell membranes.
