Question 6d
State two features that the channel proteins and carrier proteins of membranes have in common, apart from being proteins.
Selective Transport
- Both channel proteins and carrier proteins are selective, meaning they allow only specific molecules or ions to pass through the membrane based on factors like size, shape, and charge.
Facilitated Diffusion
Both types of proteins assist in facilitated diffusion, enabling substances to move across the cell membrane down their concentration gradient without requiring energy (ATP) in this process.
