question 24
how are channel and carrier proteins different from each other?
a channel proteins form open pores for molecules to pass through, while ca
b channel proteins use energy, while carrier proteins do not
c carrier proteins move any molecule, while channel proteins are only for glu
d channel proteins only work during active transport, while carrier proteins p

Explanation:

Channel proteins form open pores for molecules to pass through. Carrier proteins bind to specific molecules and change shape to transport them. Option a correctly describes this difference. Option b is incorrect as channel proteins generally do not use energy (facilitated diffusion for channel proteins can be passive, carrier proteins can be passive or active - but not as described here). Option c is wrong as channel proteins are not only for glucose. Option d is incorrect as channel proteins can work in passive transport (not just active).

Answer:

A. Channel proteins form open pores for molecules to pass through, while carrier proteins bind to specific molecules and change shape to transport them.
