What is the process that utilizes a carrier to move materials across the plasma membrane in the direction of the concentration gradient that does not use ATP?
Active Transport
What else can I help you with?
A non-energy requiring process that moves materials across a cell membrane with the concentration gradient.?
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.
Which type of transport is the coupled passage of two materials across a membrane?
Symport is the type of transport that involves the coupled passage of two materials across a membrane in the same direction. It relies on a concentration gradient to move both substances across the membrane simultaneously.
How does passive transport move substances across a cell membrane in the direction of their concentration gradient?
Passive transport moves substances across a cell membrane in the direction of their concentration gradient without requiring energy input from the cell. This process relies on the natural movement of molecules from areas of high concentration to areas of low concentration, facilitated by protein channels or carriers in the cell membrane.
What two forces drive the passive transport of ions across a membrane?
The two forces that drive passive transport of ions across a membrane are concentration gradient and electrochemical gradient. The concentration gradient occurs when ions move from an area of higher concentration to an area of lower concentration, while the electrochemical gradient is established by the combined forces of the ion's concentration gradient and the electrical charge across the membrane.
Which term describes the difference in the concentration of a substance across a cells membrane?
concentration gradient
What determineds the direction in which a substance diffuses across a membrane?
Concentration gradient determines the direction of flow.
A non-energy requiring process that moves materials across a cell membrane with the concentration gradient.?
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.
The net direction that an ion or molecule moves is?
determined by the concentration gradient and electrical gradient across the membrane. If the net movement of ions or molecules is down their concentration gradient and towards the opposite electrical charge, they will move across the membrane.
Which type of transport is the coupled passage of two materials across a membrane?
Symport is the type of transport that involves the coupled passage of two materials across a membrane in the same direction. It relies on a concentration gradient to move both substances across the membrane simultaneously.
How does passive transport move substances across a cell membrane in the direction of their concentration gradient?
Passive transport moves substances across a cell membrane in the direction of their concentration gradient without requiring energy input from the cell. This process relies on the natural movement of molecules from areas of high concentration to areas of low concentration, facilitated by protein channels or carriers in the cell membrane.
What determines the direction in a substance diffuses across a membrane?
The concentration gradient determines the direction in which a substance diffuses across a membrane. The concentration gradient is a measure of how the concentration of a substance changes from one place to another.
Which transport mechanisms moves materials across a plasma membrane against an apparent concentration gradient?
active transport
What two forces drive the passive transport of ions across a membrane?
The two forces that drive passive transport of ions across a membrane are concentration gradient and electrochemical gradient. The concentration gradient occurs when ions move from an area of higher concentration to an area of lower concentration, while the electrochemical gradient is established by the combined forces of the ion's concentration gradient and the electrical charge across the membrane.
Which term describes the difference in the concentration of a substance across a cells membrane?
concentration gradient
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.
Is the movement of molecules across a membrane down the concentration gradient a passive or active process?
The movement of molecules across a membrane down the concentration gradient is a passive process.
What determines the direction of net movement across a cellmembrane?
The direction of net movement across a cell membrane is determined by the concentration gradient of a substance, with molecules moving from an area of high concentration to an area of low concentration. Additionally, the permeability of the membrane to the specific molecules also influences their movement. External factors such as temperature and pressure can also impact the direction of movement across the membrane.
