active transport, because it uses energy , while passive transport does not
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.
The formula for active transport involves the use of energy, typically ATP, to move molecules or ions against their concentration gradient across a cell membrane. This process is carried out by specific protein pumps or transporters embedded in the membrane.
when proteins help molecules move across the membrane, it it called Facilitated Diffusion
Water diffuses across a cell membrane through a process called osmosis. Osmosis is the movement of water molecules from an area of high water concentration to an area of lower water concentration, driven by the concentration gradient of solutes across the membrane. This process helps maintain the cell's internal environment and balance the concentration of solutes inside and outside the cell.
Active Transport - the process of moving particles across a cell membrane against a concentration gradient <- right one
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.
Osmosis.
The movement of molecules across a membrane down the concentration gradient is a passive process.
Passive transport is a non-energy requiring process that moves materials across a cell membrane with the concentration gradient. This process includes simple diffusion, facilitated diffusion, and osmosis.
cell membrane is the most outer part of a cell. cell membrane is very big in surface.
The formula for active transport involves the use of energy, typically ATP, to move molecules or ions against their concentration gradient across a cell membrane. This process is carried out by specific protein pumps or transporters embedded in the membrane.
A carrier protein helps transport molecules across a cell membrane by binding to specific molecules and changing shape to move them across the membrane.
