What else can I help you with?
The transport of a substance across the cell membrane against its concentration gradient is called what?
The transport of a substance across the cell membrane against its concentration gradient is called active transport.
What barrier does active transport get substance past?
the cell membrane
What is the The uphill movement of a substance through a living cell membrane?
Active Transport
How is faciliated transport similar to active transport?
Both facilitated transport and active transport require the substance that passes the membrane to pass through intermembrane proteins. However, unlike active transport, facilitated transport does not require ATP because it is not actively going against the concentration gradient.
How can a cell transport a substance from lower to higher concentration?
A cell can transport a substance from lower to higher concentration through active transport, which uses energy to move molecules against the concentration gradient. This process typically involves the use of specialized proteins in the cell membrane to pump the molecules against the concentration gradient.
What is the difference between facilitated diffusion with the help of a carrier protein and active transport with the help of a transport transport?
Facilitated diffusion is a type of passive transport in which a substance moves across the cell membrane from high to low concentration. In this situation, the substance moves with the concentration gradient, and with the help of carrier molecules, it is able to make it's way across the membrane smoothly and without the expense of energy. Active transport, on the other hand, is the movement of a substance across the cell membrane from low to high concentration, making the transport a bit more difficult and calling for the use of energy. Transport proteins recognize the substance and allow it to cross through the membrane.
What is active transport permeable membrane?
"Active" in this context means that energy is required. A substance will flow in a certain direction, through diffusion, without having to provide additional energy. To force the substance in the opposite direction would require energy; the cell has to be "active" to achieve this, and this requires energy.
What movement of the substances through a cell membrane against a concentration gradient requires energy?
no because it is a form of passive transport. only active transport requires energy. facilitated diffusion just means that it cant be just absorbed through the membrane, it must go through specific chanels or be helped by transport proteins. but because facilitated diffusion moves from higher to lower concentrations, it requires no energy.

What is the definition of active transport?
active transport is an energy reqiuring process in which transport proteins bind with particles and move them through a cell membrane
