Energy for endocytosis, the process by which cells move large molecules like starch across the membrane, is primarily derived from ATP (adenosine triphosphate). During endocytosis, the cell membrane invaginates to engulf extracellular material, forming a vesicle that brings the material into the cell. This process requires energy to rearrange the cytoskeletal components and facilitate membrane fusion. Consequently, ATP provides the necessary energy for these cellular activities, enabling the transport of large molecules.
Water diffuses across a cell membrane through a process called osmosis. Osmosis is the movement of water molecules from an area of high water concentration to an area of lower water concentration, driven by the concentration gradient of solutes across the membrane. This process helps maintain the cell's internal environment and balance the concentration of solutes inside and outside the cell.
Active Transport - the process of moving particles across a cell membrane against a concentration gradient <- right one
when proteins help molecules move across the membrane, it it called Facilitated Diffusion

No, osmosis is a passive process that does not require the use of energy or oxygen. It is the movement of water molecules across a semi-permeable membrane from an area of high concentration to an area of low concentration. Oxygen is not involved in the process of osmosis.
Osmosis.
The movement of molecules across a membrane down the concentration gradient is a passive process.
Passive transport is a non-energy requiring process that moves materials across a cell membrane with the concentration gradient. This process includes simple diffusion, facilitated diffusion, and osmosis.
