Active transport requires energy to move molecules across the cell membrane against their concentration gradient. This process is carried out by specific proteins called pumps that utilize cellular energy in the form of ATP to transport molecules.
Active transport requires energy to move molecules across a membrane against their concentration gradient. This process is facilitated by specific carrier proteins embedded in the membrane that use energy, usually in the form of ATP, to transport molecules.
Energy for endocytosis, the process by which cells move large molecules like starch across the membrane, is primarily derived from ATP (adenosine triphosphate). During endocytosis, the cell membrane invaginates to engulf extracellular material, forming a vesicle that brings the material into the cell. This process requires energy to rearrange the cytoskeletal components and facilitate membrane fusion. Consequently, ATP provides the necessary energy for these cellular activities, enabling the transport of large molecules.
The process that requires energy to move molecules across the cell membrane is called active transport. Unlike passive transport, which relies on concentration gradients, active transport uses cellular energy, typically in the form of ATP, to move molecules against their concentration gradient. This enables cells to maintain necessary concentrations of ions and nutrients despite external conditions. Examples include the sodium-potassium pump and proton pumps.
Active transport. This process requires energy, usually in the form of ATP, to move molecules or ions against their concentration gradient across a cell membrane.
The cellular process that requires energy to transport molecules out of the cell is called exocytosis.
Active transport requires energy to move molecules across the cell membrane against their concentration gradient. This process is carried out by specific proteins called pumps that utilize cellular energy in the form of ATP to transport molecules.
You are describing active diffusion.
active transport
Active transport is the process that requires cellular energy to move a substance against its concentration gradient. This process uses ATP to pump molecules across the cell membrane, creating a concentration gradient where the molecule is more concentrated on one side of the membrane than the other.
Exocytosis is the process by which the cell directs the contents of secretory vesicles out of the cell membrane. This process occurs through the fusion of the vacuole membrane with the cell membrane.
Passive transport processes such as diffusion and osmosis do not require cellular energy. These processes involve the movement of molecules across a membrane from an area of high concentration to an area of low concentration, driven by the inherent kinetic energy of the molecules.

Active transport is the cellular movement of a substance that requires the use of energy. This process involves the movement of molecules across a cell membrane against their concentration gradient, requiring the cell to expend energy in the form of ATP. Active transport allows cells to control the internal environment and maintain homeostasis.
The process for moving cellular wastes across the cell membrane is known as active transport. Active transport is a source of energy that allows molecules to move from low concentrations to high concentrations, and provides the needed boost to move the molecules uphill.
Diffusion of molecules across the cell membrane is actually a passive process, not active. Active transport, which requires energy in the form of ATP, is a more complex process as it moves molecules against their concentration gradient.
