Active transport is a function of the cell membrane.
The cell membrane, specifically the phospholipid bilayer, is responsible for facilitating diffusion, osmosis, and active transport of molecules in and out of the cell. Various proteins, such as ion channels and pumps, play a role in active transport processes by assisting in the movement of specific molecules against their concentration gradients.
It's called active transport. When talking about the cell, it is usually bigger substances that use passages in the cell membrane to access the inner part of the cell, and they need energy to get there. The opposite; passive transport or diffusion, is the movement of dissolved materials through a cell membrane without the use of cellular energy. THis happens with smaller substances.
The cell membrane is the part of plant cells that regulates the movement of substances into and out of the cell. It acts as a barrier, allowing only specific molecules to pass through via various transport processes such as diffusion, osmosis, and active transport.
Cells need active transport to regulate their internal environment. The ability of a cell to regulate its internal environment is important because it allows the cell to add substrates to reactions that are necessary for life. Primary active transport (the movement of molecules against their electrochemical gradient) helps to power secondary active transport (or co-transport) which is the transport of an ion/molecule against its electrochemical gradient, in company with an ion/molecule being transported with its electrochemical gradient.
Respiration occurs in the mitochondria of the cell, specifically in the inner membrane where the electron transport chain and ATP synthesis take place.
The Active transport
Active transport takes place in the small intestine, where nutrients are absorbed from the intestine and into the bloodstream. More specifically, it is the structures known as villi that contain the protein receptors necessary for active transport to take place. The process also happens in the nephrons of the kidneys, where glucose and water/ions are selectively reabsorbed back into the bloodstream.
No, diffusion is where particles flow in order to be equal, whereas active transport uses ATP to move them through a cell membrane.

no proteins do not store energy they help active transport
The cell membrane is the thing that surrounds the cell. The cell membrane contains proteins that allow active transport of molecules in and out of the cell.

Active transport requires energy, unlike passive transport. The carrier proteins in active transport act as a "pump" ( fueled by ATP) to carry/attach themselfves to useful proteins for the cell.

These are three different ways that cells have to get things in and out of the cell. Passive transport is movement without the use of energy, active transport requires energy.Active transport requires energy since the molecules are going toward a region that has a higher concentration of that molecule. The cell is 'stuffing' more into itself.Endocytosis means to 'take into the cell'. Usually this a larger molecule and cell must wrap part of itself around the molecule and then can bring it inside. This is a type of phagocytosis (cell eating).This requires energy as well.
