Critically discuss the transport mechanisms across the membrane​

Diffusion, osmosis and active transport.

Explanation:

. Diffusion is the movement of substances from a region of high concentration to a region of low concentration across the membrane.

.Osmosis is the movement of water molecules from a hypotonic solution to a hypertonic solution across the membrane.

.Active transport is the movement of substances from a region of low concentration to a region of high concentration across the membrane with the utilization of energy.

hey there!

so, when you eat, your teeth chew and grind food into smaller pieces. this is mechanical digestion. then reactions aided by digestive enzymes break down large food molecules into smaller molecules. this is chemical digestion. the two processes change the food into simpler substances that can be used by the body for raw materials and energy.

hope this
