Question

Which of these provides an example of molecules moving by facilitated diffusion?
A)
Water.diffuses across the phospholipid bilayer with the gradient.
B)
Na moves through a membrane protein against the gradient to the
cytoplasm.
C)
O, moves from high concentration outside the blood cell to low
concentration inside the blood cell
Glucose moves from high concentration in the blood to lower
concentration in the cell using a membrane protein.

Answer 1

Answer:D

Explanation:

Answer 2

The movement of Na through a membrane protein against the gradient to the cytoplasm would be a good example of facilitated diffusion.

What is facilitated diffusion?

It is the diffusion of substances against their concentration gradients with the assistance of carrier molecules.

In other words, it is the movement of substances from their region of lower concentration to their region of higher concentration.

Thus, the movement of Na through a membrane protein against its own concentration gradient is an example of facilitated diffusion.
