Explain active transport?
Active transport is the movement of a substance against its concentration energy.
When a substance moves from an area of low concentration to an area of high concentration while using energy the processed is term is?
When a substance moves from an area of low concentration to an area of high concentration while using energy the process is called active transport.
How does facilitate transport differ from active transport?
Facilitated transport occurs when a substance moves from an area of higher concentration to an area of lower without the aid of energy. Active transport involves additional energy as it is moving from a lower concentration into a higher concentration.
What is the transport of materials against a concentration gradient called?
The process of moving materials against a concentration gradient is called active transport. Active transport generally uses a protein pump to move molecules from an area of low concentration to an area of high concentration; in order to perform an active transport, the cell must use some of its energy to initiate the reaction.
What is the energy source for co-transport?
The energy source for co-transport is typically the concentration gradient of one substance that is established by an active transport process. This concentration gradient drives the movement of another substance against its own concentration gradient through a symporter protein.
Is movement of a substance down its concentration gradient a passive transport?
Yes, movement of a substance down its concentration gradient is considered passive transport because it does not require energy expenditure by the cell. The substance moves from an area of high concentration to an area of low concentration through processes like simple diffusion, facilitated diffusion, or osmosis.
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
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 active transport and passive transport?
active transport requires the use of energy aka ATP and is usually against the concentration gradient. passive transport does not require energy because it moves in response to the concentration gradient.
What is the key feature of active transport?
The key feature of active transport proteins is that they can use chemical energy to move a substance against its concentration gradient. Most use energy from a molecule called ATP, either direvtly or indirectly.
What type of transport takes place when a protein allow an ion to enter a cell but no additional energy is needed to make this happen?
There are two types of transport that use channel proteins.The first type does not require energy to move the substance across the cell membrane.This is called facilitated diffusion. Energy is not required because the particles move along the concentration gradient, or the difference between the high concentration of particles outside the membrane and the low concentration of the particles inside.The second type of transport needs energy because it runs against the concentration gradient. This process is called active transport.
What is the movement of a substance from an area of high concentration to an area of low concentration?
The movement of a substance from an area of high concentration to an area of low concentration is known as diffusion. This process occurs due to the random motion of particles, leading to a net movement of particles down their concentration gradient. Diffusion is driven by the principle of entropy, seeking to achieve a state of equilibrium where the concentration of the substance is uniform throughout the system.
