If a cell is very active, it would need to have a large number of Mitochondria.
No, exocytosis is not considered a form of passive transport. It is an active process where cells expel materials by fusing vesicles with the cell membrane.
No, endocytosis and exocytosis are forms of active transport, not passive transport. Endocytosis is the process by which cells take in particles by engulfing them in a vesicle, while exocytosis is the process by which cells expel materials by fusing vesicles with the cell membrane. Both processes require energy to accomplish.
Large molecules or particles such as proteins, lipids, polysaccharides, and even whole cells are typically transported through endocytosis and exocytosis, as they are too large to pass through the cell membrane via diffusion or active transport. Endocytosis brings substances into the cell by engulfing them in a vesicle, while exocytosis expels substances out of the cell by merging vesicles with the cell membrane.
There are three types of active transport. They are endocytosis, exocytosis, and sodium potassium pump. Endocytosis is when the cells ingest substances. Exocytosis is the process of releasing contents of the cell to the external environment.
In the intestines, cells use active transport to pump nutrients such as glucose and amino acids from the intestinal lumen into the bloodstream. In the kidney, cells actively transport ions and small molecules from the blood into the nephron tubules for excretion in urine. In nerve cells, active transport is used to maintain the concentration gradients of sodium and potassium ions across the cell membrane, essential for nerve signaling.

Both processes require energy to accomplish.
Endocytosis and exocytosis involve the transport of molecules across a cell membrane using energy in the form of ATP. In endocytosis, cells engulf substances by creating vesicles, and in exocytosis, cells expel substances by fusing vesicles with the cell membrane. Both processes require energy to move substances against their concentration gradient, making them examples of active transport.
No, exocytosis is an active process where cells release substances by fusing vesicles with the cell membrane to expel contents out of the cell. Passive transport does not require energy input, whereas exocytosis involves energy in the form of ATP to carry out the process.

Endocytosis brings substances into the cell by engulfing them in a vesicle, while exocytosis expels substances out of the cell by merging vesicles with the cell membrane.
Proteins or other molecules that need to be transported out of the cell are likely to exit via exocytosis. Exocytosis is a process in which vesicles fuse with the cell membrane to release their contents outside the cell. This is how cells release hormones, neurotransmitters, and other signaling molecules.

exocytosis which is when cells absorb materials from outside the cell by engulfing it with their cell membrane
Materials can move in and out of animal cells through one of two reasons: Passive transport or active transport. Passive transport happens naturally and requires no energy on the part of the cell. It usually happens through osmosis, diffusion, or facilitated diffusion. Active transport involves endocytosis, exocytosis, or molecules moving from a low concentration to high concentration. Active transport requires energy.
Cells use exocytosis to release hormones, neurotransmitters, and enzymes into extracellular spaces. It is also involved in the secretion of waste materials from cells. Additionally, some cells use exocytosis to insert new proteins into the cell membrane.
