How do solutes get in and out of the cell?
Solutes can enter and exit cells through various mechanisms such as passive diffusion, facilitated diffusion, active transport, and endocytosis/exocytosis. Passive diffusion occurs when solutes move across the cell membrane down their concentration gradient. Facilitated diffusion involves the use of transport proteins to help solutes cross the membrane. Active transport requires energy to move solutes against their concentration gradient. Endocytosis and exocytosis involve the cell engulfing or releasing solutes by forming vesicles.
What controls diffusion and osmosis in and out of a cell?
Diffusion and osmosis in and out of a cell are primarily controlled by the concentration gradient of solutes. Diffusion is the movement of molecules from an area of high concentration to low concentration, while osmosis is the movement of water across a selectively permeable membrane to equalize solute concentrations. Additionally, the permeability of the cell membrane to different solutes and the presence of transport proteins can also influence the rate of diffusion and osmosis.
Are aquaporins involved in osmosis or facilitated diffusion?
Aquaporins are involved in osmosis by facilitating the movement of water molecules across cell membranes. They do not participate in facilitated diffusion, which involves the transport of solutes across membranes with the help of carrier proteins.
Does facilitated diffusion require ATP?
In cells, passive diffusion is energy independent and therefore does not require ATP. This is opposed to active transport which requires either energy in the form of ATP or a charge gradient to move a molecule or ion across the membrane.
How is facilitated diffusion diferant froma an active transport?
Facilitated diffusion is a type of passive transport which does not require the cell to expend energy.

How do products of the cell get out of the cell?
Diffusion, facilitated diffusion, passive transport, facilitated transport (?) and active transport ... unless we are referring to viral or bacterial products.
What moves small or lipid soluble solutes through the membrane?
Small or lipid soluble solutes can pass through the cell membrane via simple diffusion. This process occurs without the need for energy or specific transport proteins, as these solutes can move freely through the lipid bilayer of the membrane due to their size or lipid solubility.
What type of transport is it when gluclose molecules move into a cell?
Glucose molecules entering a cell typically occurs through facilitated diffusion, which is a type of passive transport. This process involves the movement of glucose across the cell membrane with the help of specific transporter proteins.
What are the three transport processes that do not require cell energy?
Passive Transport,Facilitated Diffusion, and Simple Diffusion
What 3 ways can substances enter and leave a cell?
Substances can move in and out of a cell in several ways. Diffusion is when a substance will distribute itself in or out of a cell until the distribution on both sides of the cell is balanced. Active transport is when a cell transports a substance across the cell membrane that would not normally be able to pass through. Osmosis is the movement of water from areas with few dissolved dissolved substances to areas with high dissolved substances.
What types of transport mechanisms through the cell membrane are passive?
diffusion, facilitated diffusion, and osmosis
Does facilitated diffusion require energy to transport molecules across the cell membrane?
Facilitated diffusion does not require energy to transport molecules across the cell membrane.
Which transport does not require cell energy?
Diffusion is per definition a passive transport process.
Does facilitated diffusion require ATP?
In cells, passive diffusion is energy independent and therefore does not require ATP. This is opposed to active transport which requires either energy in the form of ATP or a charge gradient to move a molecule or ion across the membrane.
