How does active transport work against the concentration gradient to move substances across a cell membrane?
Active transport is a process in which cells use energy to move substances against their concentration gradient, from an area of low concentration to an area of high concentration, across the cell membrane. This is achieved by using specialized proteins called pumps that actively transport the substances across the membrane, requiring energy in the form of ATP.
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.
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 are responsible for the transport of substances down a concentration gradient during facilitated diffusion?
Transport proteins embedded in the cell membrane are responsible for facilitating the movement of substances down a concentration gradient during facilitated diffusion. These transport proteins provide a pathway for specific molecules to pass through the membrane, allowing them to move from an area of high concentration to an area of low concentration.
What is the type of transport in which a cell goes against the concentration gradient in order to diffuse substances within?
Active transport is the type of transport in which a cell moves substances against their concentration gradient, requiring energy to do so. This process helps maintain the internal balance of substances within the cell.
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.
How does difference in concentration relate to movement of substances across the membrane?
the concentration gradient will help to bring stuff into the cell and to move stuff out. Osmosis likes to move with the concentration gradient. Moving with a concentration gradient is passive transport and moving against it is active transport

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.
Active transport requires what?
Energy-requiring process by which substances move across the plasma membrane against a concentration gradient.
In which type of process do substances move down their concentration gradient across the membrane?
Active transport is a process that removes substances from a cell against the concentration gradient. The molecules move from low concentration to high concentration during this process.

What form of transport is not a form of passive transport?
Active transport requires energy to move substances across a cell membrane against their concentration gradient, whereas passive transport does not require energy and relies on the concentration gradient. Examples of active transport include the sodium-potassium pump and endocytosis.
What is the process that requires cellular energy to move a substance against its concentration gradient?
Active transport is the process that requires cellular energy to move a substance against its concentration gradient. This process uses ATP to pump molecules across the cell membrane, creating a concentration gradient where the molecule is more concentrated on one side of the membrane than the other.
How does active transport move substances against the concentration gradient?
Active transport moves substances against the concentration gradient by using energy from ATP to pump molecules or ions across the cell membrane, creating a higher concentration on one side than the other. This process allows the cell to maintain internal balance and control the movement of specific substances.
Is active transport not spontaneous?
Active transport is not spontaneous because it requires energy input to move substances against their concentration gradient. This process is driven by specific transporter proteins in the cell membrane that utilize ATP to pump molecules across the membrane. Unlike passive transport, which occurs spontaneously with the concentration gradient, active transport is a non-spontaneous process.
