What barrier does active transport get substance past?
the cell membrane
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.
How do you use active transport in a sentence?
Active transport is the movement of a substance across a cell membrane from low to high concentration with the help of energy.
How might life be different if cells had to use active transport to move every substance?
Life would be very difficult and processes would drag if cells were to use active transport to move every substance to its destination.
Is diffusion an active mechanism?
False
Explain active transport?
Active transport is the movement of a substance against its concentration energy.
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.
How do carrier proteins recognize substances to transport in active transport?
substance to pass
How do carrier protein recognize substances to transport in active transport?
substance to pass
What barrier does active transport get substance past?
the cell membrane
Term for the movement of substance against a concentration gradient?
active transport eduction. this is the process in which this moves across. peanut butter jelly time
What processes could result in the net movement of a substance into a cell if the substance is more concentrated in the cell than in the surroundings?
Active transport or facilitated diffusion could result in the net movement of a substance into a cell if it is more concentrated inside the cell than in the surroundings. In active transport, energy is required to move the substance against its concentration gradient. In facilitated diffusion, specific carrier proteins help the substance move into the cell down its concentration gradient.
What is used to move a substance through a membrane in active transport?
Electrochemical gradient is used to move substances through a membrane in active transport.
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).
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.
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.
When a substance moves from an area of low concentration to an area of high concentration while using energy the proces is termed what?
active transport
