which of the following transport mechanisms does not require additional energy expenditure
A. active transport
b. carrier-mediated diffusion
C. simple diffusion
Homework Answers
The answer is C. Simple diffusion.
Any transport which utilizes energy those are considered as active transport, so the option A is wrong. The carrier mediated diffusion also utilizes energy for one side so, it is also wrong.

A correct distinction between facilitated diffusion and active transport of a substance across a biological membrane is that . . . A. active transport requires conformational changes in the transport protein associated with the transport process, and facillitated diffusion does not. B. active transport requires integral membrane protein to carry out the transport, and facillitated diffusion does not. C. facilitated diffusion depends on an existing energy gradient acting on the transported substance, while active transport makes such a gradient. D....
