Which one of the following statements is correct? Statement (I): Faciliated diffusion is an active absorption which require membrane protein. Statement (II): Faciliated diffusion occurs with the help of Aquaporins and ion channels.
Options
- AStatement I only
- BStatement II only
- CBoth statement I and II
- DNeither statement I nor statement II
Correct answer
B. Statement II only
Step-by-step solution
Statement (I) is incorrect because facilitated diffusion is a passive process, not an active absorption. It occurs along the concentration gradient and does not require energy (ATP), although it does require membrane proteins. Statement (II) is correct because facilitated diffusion of water and ions occurs with the help of specific channel proteins like aquaporins and ion channels, respectively. Therefore, only Statement II is correct. Answer: Statement II only
