Question

which movement of particles would be most affected by a disorder that causes damage to carrier proteins?
osmosis
passive transport
active transport
diffusion

Explanation:

Osmosis is the diffusion of water across a semi - permeable membrane and doesn't require carrier proteins. Passive transport includes simple diffusion (no carrier proteins) and facilitated diffusion (uses carrier or channel proteins). Diffusion is the movement of particles from high to low concentration and simple diffusion doesn't need carrier proteins. Active transport is the movement of particles against their concentration gradient and always requires carrier proteins to move substances across the cell membrane. So damage to carrier proteins would most affect active transport.

Answer:

C. active transport
