Direct link to Sarah King's post Simple diffusion is the m, Posted 7 years ago. a) entropy has decreased Some channel proteins are open all the time, but others are gated, meaning that the channel can open or close in response to a particular signal (like an electrical signal or the binding of a molecule). Enzymes that normally work in alkaline environments in the body can become denatured if the pH becomes too acidic. On this side of the cell, we can also see oxygen and carbon dioxide diffusing across the lipid bilayer. ATP, Which are materials found in a molecule of ATP? For example, oxygen might move into the cell by diffusion, while at the same time, carbon dioxide might move out in obedience to its own concentration gradient.
