To start the process ATP is required to transport glucose milecules across the cell membranes of the intestine.
Active Transport
They control what enters and exits the cell :)
diffusion
the movement of materials against a concentration difference is known as active transport. Active transport requires energy.

Active Transport
Passive transport and active transport are transport of materials across membranes. Passive requires no energy, while active does.
well oxygen isn't a transport system it is something that can be diffused across the membranes of cells.
Transport proteins change shape, much like a folding door

Ions can't diffuse across membranes, they must used channels to transport across
diffusion
Diffusion
Passive transport is the movement of substances across a cell membrane without the use of energy. It occurs along a concentration gradient, with substances moving from an area of high concentration to an area of low concentration. Examples include diffusion and facilitated diffusion.
active transport
the movement of materials against a concentration difference is known as active transport. Active transport requires energy.
