Active transport.


Which type of transport requires energy to move sodium ions from a low concentrations across the intestinal wall into a higher concentrations?

Active transport.


What is the name of cellular process in which materials are moved across a membrane from an area of low concentration to an area of high concentration?

active transport


What is difference between active transport and passive transport?

One difference is energy consumption. Active transport requires the cell to expend energy, while passive transport does not. Active transport is movement from a lower concentration to a higher concentration and passive transport is movement from a higher concentration to a lower concentration. Active transport is the movement of molecules across a membrane requiring energy to be expended by the cell. Passive transport is diffusion across a membrane requiring only random motion of molecules with no energy expanded by the cell. Active transport requires ATP to transport materials. Passive transport does not require ATP input to transport materials. Ex: diffusion


Is active or passive transport involved?

In active transport the ATP is used to pump molecules up the concentration gradient. Transport of molecules occurs from a low concentration of solute to high concentration of solute and requires cellular energy. While passive transport involves carriers, channels, or direct diffusion through a membrane.

Active transport requires what?

Energy-requiring process by which substances move across the plasma membrane against a concentration gradient.


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.


What is the function of active transport in moving small molecules and ions across the membranes?

the movement of materials against a concentration difference is known as active transport. Active transport requires energy.


What is the movement of molecules across a membrane against their concentration at the expense of ATP energy called?

Active transport. It requires energy in the form of ATP to move molecules against their concentration gradient.


Examples of active transport?

Active transport is the movement of ions or molecules across a cell membrane into a region of higher concentration, which requires energy and is assisted by enzymes. Examples of active transport are: the uptake of glucose in the intestines of people and the uptake of mineral ions into the root hairs of plants.


Active transport is the process of what?

Active transport is the process by which a cell uses energy to move molecules or ions across a cell membrane against their concentration gradient. This process requires the use of ATP energy to pump substances from an area of low concentration to an area of high concentration.
