What else can I help you with?
What is the name of cellular process in which materials are moved across a membrane from an area of low concentration to an area of high concentration?
active transport
What is the movement of molecules across a membrane against their concentration at the expense of ATP energy called?
Active transport. It requires energy in the form of ATP to move molecules against their concentration gradient.
Is Active transport high to low or low to high concentration?
Active transport. To go "upstream" requires ATP, a form of energy, to pump against the ion gradient.
How are facilitated diffusion and active transport different in terms of their mechanisms of transporting molecules across the cell membrane?
Facilitated diffusion uses transport proteins to move molecules across the cell membrane with the concentration gradient, while active transport requires energy to move molecules against the concentration gradient.
Is active transport low concentration to high concentration?
Yes. Active transport requires energy; it is transport from an area of low concentration to an area of high concentration. Passive transport doesn't require energy; it is transport from an area of high concentration to an area of low concentration.
Which type of transportation requires energy to move sodium ions from a low concentration across the intestinal wall into a higher concentration?
Active transport.
Which type of transport requires energy to move sodium ions from a low concentrations across the intestinal wall into a higher concentrations?
Active transport.
What is the name of cellular process in which materials are moved across a membrane from an area of low concentration to an area of high concentration?
active transport
What is difference between active transport and passive transport?
One difference is energy consumption. Active transport requires the cell to expend energy, while passive transport does not. Active transport is movement from a lower concentration to a higher concentration and passive transport is movement from a higher concentration to a lower concentration. Active transport is the movement of molecules across a membrane requiring energy to be expended by the cell. Passive transport is diffusion across a membrane requiring only random motion of molecules with no energy expanded by the cell. Active transport requires ATP to transport materials. Passive transport does not require ATP input to transport materials. Ex: diffusion
Is active or passive transport involved?
In active transport the ATP is used to pump molecules up the concentration gradient. Transport of molecules occurs from a low concentration of solute to high concentration of solute and requires cellular energy. While passive transport involves carriers, channels, or direct diffusion through a membrane.
What is the different between passive and active transport?
One difference is energy consumption. Active transport requires the cell to expend energy, while passive transport does not. Active transport is movement from a lower concentration to a higher concentration and passive transport is movement from a higher concentration to a lower concentration. Active transport is the movement of molecules across a membrane requiring energy to be expended by the cell. Passive transport is diffusion across a membrane requiring only random motion of molecules with no energy expanded by the cell. Active transport requires ATP to transport materials. Passive transport does not require ATP input to transport materials. Ex: diffusion
Active transport requires what?
Energy-requiring process by which substances move across the plasma membrane against a concentration gradient.
What is the differece between passive and active transport?
Active transport is the movement of molecules across a membrane requiring energy to be expanded by the cell. ACTIVE TRANSPORT REQUIRES ENERGY. Passive transport is diffusion across a membrane requiring only random motion of molecules with no energy expanded by the cell. PASSIVE TRANSPORT REQUIRES NO ENERGY.
What is the function of active transport in moving small molecules and ions across the membranes?
the movement of materials against a concentration difference is known as active transport. Active transport requires energy.
What is the movement of molecules across a membrane against their concentration at the expense of ATP energy called?
Active transport. It requires energy in the form of ATP to move molecules against their concentration gradient.
Examples of active transport?
Active transport is the movement of ions or molecules across a cell membrane into a region of higher concentration, which requires energy and is assisted by enzymes. Examples of active transport are: the uptake of glucose in the intestines of people and the uptake of mineral ions into the root hairs of plants.
Active transport is the process of what?
Active transport is the process by which a cell uses energy to move molecules or ions across a cell membrane against their concentration gradient. This process requires the use of ATP energy to pump substances from an area of low concentration to an area of high concentration.
