"Active Transport" is the answer given
but if it is the passive movement then no energy is required so isn't it facilitated diffusion?

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.
What two forces drive the passive transport of ions across a membrane?
Two forces drive the passive transport of ions across a membrane: -the concentration gradient of the ions -the effect of membrane potential (voltage) on the ions
A non-energy requiring process that moves materials across a cell membrane with the concentration gradient.?
The process of moving materials across the cell membrane without the expenditure of energy is called passive transfer
A type of transport across a membrane up its concentration gradient using protein carriers and driven by the expenditure of chemical energy is known as what?
This is a description of active transport.
What is the movement of chemical substances usually across the cell membrane againts a concentration gradient requires cells to energy?
active transport
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.
What facilitated passive transport across a cell membrane?
concentration gradient
What facilities passive transport across a cell membrane?
concentration gradient.
Which transport mechanisms moves materials across a plasma membrane against an apparent concentration gradient?
active transport
What process drives molecules across a membrane against a concentration gradient?
Active Transport.
Which process moves an ion across a cell membrane against a concentration gradient?
ative transport
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
What two forces drive the passive transport of ions across a membrane?
Two forces drive the passive transport of ions across a membrane: -the concentration gradient of the ions -the effect of membrane potential (voltage) on the ions
When would active transport be used by a cell?
Active transport is used when molecules are moved across a cell membrane against their concentration gradient, from a low to a high concentration.
Is the process in which molecules move across a cell membrane from a region of low concentration to a region of high concentration.?
Active Transport - the process of moving particles across a cell membrane against a concentration gradient <- right one
What is the process in which molecules move across the cell membrane from a region of low concentration to a region of high concentration?
Active Transport - the process of moving particles across a cell membrane against a concentration gradient <- right one
What is primary active transport?
Primary active transport is defined as utilizing energy in the form of ATP to transport molecules across a membrane against their concentration gradient. This means moving from a low concentration to a high concentration.
