What are the two general types of transport used by cells to transport materials in and out of the cell?

The two general types of transport used by cells are passive transport, which does not require energy and includes processes like diffusion and osmosis, and active transport, which requires energy and involves processes like protein pumps and vesicle transport.


What proteins are used in both active and passive transport?

Transport proteins such as ion channels and carrier proteins are used in both active and passive transport processes. Ion channels move ions down their concentration gradient through passive transport, while carrier proteins can facilitate passive transport by allowing molecules to move along their concentration gradient, or active transport by requiring energy to transport molecules against their concentration gradient.


Where do the electrons used in the electron transport chain come from?

The electrons used in the electron transport chain come from the breakdown of molecules like glucose during cellular respiration.


Which type of transport is used to move a molecule for a region of low concentration to a region of high concentration?

Active transport is used to move a molecule from a region of low concentration to a region of high concentration. This process requires energy input in the form of ATP to pump the molecule against its concentration gradient.
