What is the compare and contrast of osmosis and diffusion to exocytosis and endocytosis?
Osmosis and diffusion are passive transport processes that involve the movement of molecules across a membrane or within a solution, driven by concentration gradients. In contrast, exocytosis and endocytosis are active transport processes that require energy to move large molecules or particles into (endocytosis) or out of (exocytosis) cells via vesicles. While osmosis specifically refers to the movement of water, diffusion can involve any type of molecule. Overall, osmosis and diffusion are simpler, passive mechanisms, whereas exocytosis and endocytosis are more complex, energy-dependent processes.
Does endocytosis occur in prokaryotes?
Yes, endocytosis does not occur in prokaryotes because they lack membrane-bound organelles and do not perform phagocytosis, pinocytosis, or receptor-mediated endocytosis like eukaryotic cells. Instead, prokaryotes rely on other mechanisms such as simple diffusion, facilitated diffusion, and active transport to take in nutrients and molecules.
Does diffusion endocytosis active transport or sodium potassium pump not require energy?
Diffusion and endocytosis are processes that do not require energy; diffusion occurs naturally as molecules move from areas of higher to lower concentration. Endocytosis, while it involves the engulfing of materials into the cell, is considered an active process and does require energy in the form of ATP. In contrast, the sodium-potassium pump is an active transport mechanism that also requires energy to move sodium and potassium ions against their concentration gradients. Thus, diffusion is passive, while endocytosis and the sodium-potassium pump are active processes that require energy.
How does all the material required by the cell get into the cell?
Via endocytosis, active transport and facilitated passive transport and diffusion.
Diffusion of AIDS is an example of which type of diffusion?
Diffusion of AIDS is an example of contagious diffusion, where the disease spreads through direct or indirect contact between individuals.
Movement of large molecules into a cell is called?
hydrogen bondingANS2:Substances are moved into cells by both active transport and passive transport. An example of active transport is "Endocytosis". An example of passive transport is "Diffusion".
Are nutrients absorbed passively or actively in the digestive tract?
Both, depending on the size of the nutrient. Much of absorption works through either endocytosis or transport of small molecules by simple diffusion. Simple diffusion and facilitated diffusion are both types of passive transport and endocytosis requires energy.

How do endocytosis and exocytosis differ from diffusion?
i know a ton about this, learned it last year! Endocytosis is when a cell absorbs a protien by engulfing it. Exocytosis is the oppisite of endocytosis. This is how waste is produced (cell waste). It is the release of cell surface's substances through vesicles. TO remeber which is which just think of exocytosis as the waste is EXITING the cell and endocytosis is protiens ENtering the cell
What is an example of mediation?
endocytosis

What is endocytosis an example of?
Endocytosis is a process by which cells engulf external particles or fluid to bring them into the cell. An example of endocytosis is the uptake of nutrients by cells, such as the absorption of fats or proteins from the digestive system.
How does all the material required by the cell get into the cell?
Via endocytosis, active transport and facilitated passive transport and diffusion.
Is the action of a macrophage an example of endocytosis?
Yes, the action of a macrophage involves endocytosis. Macrophages are immune cells that engulf and internalize pathogens, cellular debris, and other foreign particles through a process called phagocytosis, which is a type of endocytosis.
How do proteins and polysaccharides that are too large to move onto a cell through diffusion or active transport move into the cell by?
Endocytosis.
What is a example of endocytosis and exodytosis?
white blood cell
