Type of transport that requires no energy where the molecules move until equilibrium is reached?
not sure
What type of transport requires energy to move molecules from an area with low concentration to an area of high concentration?
Active transport is needed to move molecules from an area of low concentration to an area of higher concentration against their concentration gradient. ATP is used as the power source.
Which type of transport uses energy passive or active transport?
Active transport because it move up the concentration gradient which requires energy to do so. Where as the passive transport goes down the concentration which does not need energy.
Is channel-mediated diffusion a form of active transport?
Yes, when channels are specific for the structures of individual molecules it is active transport. Active transport cannot occur if the energy they are moving is not of the same type, like glucose cannot move calcium.
What is the differece between passive and active transport?
Active transport is the movement of molecules across a membrane requiring energy to be expanded by the cell. ACTIVE TRANSPORT REQUIRES ENERGY. Passive transport is diffusion across a membrane requiring only random motion of molecules with no energy expanded by the cell. PASSIVE TRANSPORT REQUIRES NO ENERGY.

not sure
What type of transport requires energy to move molecule?
Active transport requires energy to move a molecule.
What type of transport requires energy move a molecule?
Active transport requires energy to move a molecule.
What type of transport is it when gluclose molecules move into a cell?
passive. any transport that is diffusion to get into a cell is passive.
What type of transportation requires energy to move a molecule?
Active transport requires energy to move a molecule.
What type of transport requires energy to move molecules from an area with low concentration to an area of high concentration?
Active transport is needed to move molecules from an area of low concentration to an area of higher concentration against their concentration gradient. ATP is used as the power source.
If the substance entering the cell was in higher concentration inside the cell then outside the cell what type of transport would be required?
It would be active transport, a process which requires a cell to use its own energy (unlike passive transport).
What type of passive transport is when molecules move from where there are more of them to an area where there are less?
Diffusion is the form of passive transport that moves particles away from areas with more particles into areas with fewer particles.
How is active transport diffrent from osmosis?
Active transport occurs when molecules are moved from an area of low concentration to an area of high concentration. The cell membrane acts as a semi-permeable barrier during the process. Energy is required for active transport. Osmosis is a type of passive transport. Passive transport is similar to active transport except it requires no energy and molecules move from an area of high concentration to an area of low concentration. Osmosis occurs only if the molecules moving across the cell membrane are WATER molecules.
What is the type of transport in which a cell goes against the concentration gradient in order to diffuse substances within?
Active transport is used to move molecules and ions across a membrane against their concentration gradient. "Active" means that the transporter requires energy to do its job (eg. glucose).
Which type of transport requires energy to move sodium ions from a low concentrations across the intestinal wall into a higher concentrations?
Active transport.
Which type of transport requires assistance from membrane proteins?
cellular transport nop, is passive transport
