Verified step by step guidance1
Understand the concept of diffusion: Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration. It does not require energy or a carrier protein.
Learn about facilitated diffusion: Facilitated diffusion is similar to diffusion but involves the use of carrier proteins to transport molecules across the cell membrane. It does not require energy.
Explore active transport: Active transport is the movement of molecules against their concentration gradient, from an area of lower concentration to an area of higher concentration. This process requires energy and a carrier protein.
Examine endocytosis: Endocytosis is a process where the cell membrane engulfs material to bring it into the cell. It does not require a carrier protein but involves the formation of vesicles.
Identify processes requiring carrier proteins: Facilitated diffusion and active transport both require carrier proteins to move substances across the cell membrane.
