Large molecules are typically moved into the cell during a process called "endocytosis". During this process, a molecule binds to a "receptor" protein, a cell surface protein which is anchored within the cell membrane. The cell then begins to fold the membrane inward, forming a pocket called an "invagination" which contains the molecule bound to the receptor. Eventually, the invagination pinches off the cell membrane and becomes a small vacuole, or an "endosome". These endosomes can be moved throughout the cell to where the large molecules are needed or processed. If the large molecule is needed within the cytoplasm, it is transported out of the endosome through a protein complex that forms a pore across the endosome membrane. These transport processes all require the use of ATP.
What else can I help you with?
Is The high concentration of mineral ions in the plant cells causes water molecules to move into the plant by diffusion?
Yes, high concentrations of mineral ions in plant cells create an osmotic gradient, causing water molecules to move into the plant cells by osmosis. This helps maintain turgor pressure, which is essential for plant cell structure and function.
How do cells balance concentrations?
Cells balance concentrations by using various mechanisms such as passive diffusion, active transport, and osmosis. Passive diffusion allows molecules to move across the cell membrane from an area of high concentration to an area of low concentration. Active transport requires energy to move molecules against their concentration gradient. Osmosis involves the movement of water across the cell membrane to equalize solute concentrations inside and outside the cell.
How do substances like co2 and water move in and out of the cell?
By the process of diffusion and osmosis.
What is it called when vesicles are used to move substances out of the group?
Exocytosis is the process where vesicles fuse with the plasma membrane to release substances outside of the cell. This mechanism allows cells to expel waste or deliver molecules to other cells.
What moves substances in and out of a cell?
Substances are moved in and out of a cell through various processes such as diffusion, facilitated diffusion, active transport, and endo/exocytosis. These processes involve either the movement of molecules down their concentration gradient or the use of energy to transport molecules against their concentration gradient.
How do large cells move across the cell membrane?
There cannot be large cells inside a cell.
In which process in which process this is so you molecules does the cell use a vesicles to move molecules into the cell?
cells
Do large cells move across the cell membrane quickly?
A large cell will never move across an intact cell membrane.
What process does the cell use a vesicle to move molecules out of the cells?
Exocytosis is the process that moves molecules from the inside of the cell to the outside. This process uses sacs or vesicles to move the molecules out.
Why molecules move into and out of cells?
Molecules move in and out of the cell by difffusion process and only those molecules which have size smaller then pore size of plasma membrane can move in and out of the cell. The second factor is ionic conc or is also known as conc gradient according to which molecules of required ionic status can move in and out of the cell
In which process does a cell use a vesicle to move molecules into the cells?
Endocytosis (APEX)
Infer why endocytosis and exocytosis are important processes to cells?
because some molecules and partcles are too large to move by diffusion or to use the cell membranes transport proteins.
Must sugar dissolve in blood to enter cells?
No, sugar enters cells through facilitative diffusion, a process that does not require it to dissolve in blood. Cells use specialized transport proteins to move sugar molecules from the blood into the cell.
What is diffusion in cells?
Diffusion in cells is the process by which molecules move from an area of high concentration to an area of low concentration. This movement occurs naturally due to the random motion of molecules and does not require energy input from the cell. Diffusion plays a crucial role in transporting essential nutrients, gases, and signaling molecules across cell membranes.
What two processes move large packets of molecules across the cell membrane?
osmosis and diffusion
Can hydrophilic molecules readily move unaided into and out of cells?
Hydrophilic molecules cannot easily cross the hydrophobic lipid bilayer of cell membranes. They typically require the assistance of specific transport proteins or channels to move in or out of cells.
Why did molecules move in and out of the cell?
it gets easier as the cells move in and out because the nucleus helps push through the core. just kidding, i have no idea
