what is meant by "passive" and "active" cellular transport? what are some different types of channel proteins ?

Homework Answers

Answer #1

Passive cellular transport occurs along concentration gradient and does not require ATP

Active transport occur against concentration gradient and requires ATP

Channel protein spans the entire membrane and can be gated or non gated

Non gated : such channel protein remain open and allow water and other ions to pass through the hydrophobic membrane

Gated: such channel stays closed until it receives a chemical or electrical signal ....our nerve signals are passed on through a gated channel protei
