Define the following types of transport: Passive Transport (no energy required)

Question

Diffusion: ____ __________
Facilitated Diffusion: ______________
Osmosis: ______________

Answer 1

Sure! Here are the definitions for the types of passive transport you requested:

1. Diffusion: The process by which molecules move from an area of higher concentration to an area of lower concentration, resulting in an even distribution of particles in a given space.

2. Facilitated Diffusion: A type of passive transport that utilizes specific membrane proteins (such as carrier proteins or channel proteins) to help move molecules across the cell membrane down their concentration gradient without the use of energy.

3. Osmosis: The diffusion of water across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration until equilibrium is reached.

All these processes occur without the expenditure of cellular energy (ATP).
