When a substance wants to enter the cell it binds to what?
When a substance wants to enter a cell it goes through the cell membrane in a process called endocytosis.
When molecules cannot diffuse across the cell membrane?
Cells have a variety of molecule attached to their membranes. Some of these molecules respond to different stimuli and allow substance to pass in and out of the cell. They can voltage gated, ion gated channels, ligand gated. Cells also engage in pinocytosis, phagocytosis, and exocytosis. This is when the cell membrane engulfs a substance and takes it it or when a membrane bound vesicle fuses with the cell membrane to expel a substance.
What must a substance pass through to enter or leave a cell?
A substance must pass through the cell membrane in order to enter or leave a cell. This process can occur through various methods such as simple diffusion, facilitated diffusion, active transport, or endocytosis/exocytosis. The cell membrane acts as a barrier that selectively allows certain substances to pass through while blocking others.
Can phenolphthalein pass through a cell membrane?
No, phenolphthalein cannot pass through a cell membrane on its own. It requires a carrier protein or a specific transport mechanism to facilitate its entry into a cell.
4 substance that enters and leaves through the cell membrane?
food enters, waste leaves
What is an impermeable solute?
An impermeable solute is a substance that cannot pass through a semipermeable membrane, such as a cell membrane. This means that the solute is unable to diffuse or move across the membrane and remains on one side of the membrane.
Osmosis is the diffusion of what substance through a cell membrane?
Water
What is the procces by which a substance is released from the cell through a vesicle that transports the substance to the cell surface in then fuses with the membrane to let the substance out?
exocytosis
When a substance wants to enter the cell it binds to what?
When a substance wants to enter a cell it goes through the cell membrane in a process called endocytosis.
Which molecules cannot pass through the membrane?
Large molecules such as proteins and nucleic acids cannot pass through the cell membrane.
What is the process by which a substance is released from the cell through a vesicles that fuses with the membrane to let the substance out?
Exocytosis
The cell membrane allows some substance to pass through it and exclude others this is possible because the cell membrane is?
semi permeable
What are molecules that helps control the movement of a substance through the cell membrane?
Proteins
What is the semipermeable membrane?
The cytoplasm of a cell is surrounded by a cell membrane or plasma membrane. The membrane is said to be 'semi-permeable', in that it can either let a substance pass through freely, pass through to a limited extent or not pass through at all.the membrane is somewhat effective at letting fluids through
What substance crosses the cell membrane through osmosis?
Only water is transported through the process of osmosis.
