What are 2 situations which active transport would be required?

well if the active transport was not used it would have to use the passive transport. the meaning of not using the active transport because if you use the active transport in one case it would burst

∙ 12y agoI no one reason is If I ions are moving through the cell
Wiki User
∙ 11y agoA cell needs to use active transport instead of diffusion to transport protein to specific areas of the cell and to transport ions & chemicals against their concentration gradient.

How are minerals transported by plants?
Plants employ osmosis to move minerals into plant root cells. To transport minerals to the plant proper, energy is required so active transport is employed.
What means of particle transport requires input of energy in a cell?
Active transport is the term used to define the means of particle transport that requires input of energy from the cell. The opposite of this would be passive transport.
What is a demonstration to show active transport?
Active transport is when cells must move materials in a direction against a concentration gradient. Proteins transporting molecules across cell membranes is an example. Active transport requires energy as opposed to passive transport
How is diffusion different from active transport?
active transport is different from diffusion. active transport has to do with the movement of chemical substance through a gradient of concentration. diffusion has to do with requiring the expenditure of energy
How are active transport and passive transport different from each other?
The most basic difference between active and passive transport is that active requires energy while passive does not. You would require active transport if the substance is going against the concentration of molecules inside and outside of the membrane or if the substance is particularly large. Passive is more for smaller molecules that go with the concentration of the molecules inside and outside of the membrane.
If the substance entering the cell was in higher concentration inside the cell then outside the cell what type of transport would be required?
It would be active transport, a process which requires a cell to use its own energy (unlike passive transport).

What is the process of osmosis and active transport?
a cellular transport is a plant or a cell that moves from one place to another and they would try to connect
What is the active transport and passive transport?
Active transport is the movement of a substance across a cell membrane against its concentration gradient and Passive transport means moving biochemicals and other atomic or molecular substances across membranes.
What means of particle transport requires input of energy in a cell?
Active transport is the term used to define the means of particle transport that requires input of energy from the cell. The opposite of this would be passive transport.
How is the active transport different from diffusion?
The main difference is that diffusion does not require energy and active transport does require energy. Just for the record diffusion has a concentration that moves from high to low, and active transport has a concentration that moves from low to high. (Hope this helps to answer your question!)
Are diffusion and osmosis types active transport?
No. (Active xport would be in the opposite direction.)
Which type of cell transport does not expend energy?
Active transport is when the cell moves particles from an area of low concentration on one side of the cell membrane, to an area of high conc. on the other side, by means of a protein embedded in the membrane.
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.
What is a demonstration to show active transport?
Active transport is when cells must move materials in a direction against a concentration gradient. Proteins transporting molecules across cell membranes is an example. Active transport requires energy as opposed to passive transport
What is active transport permeable membrane?
"Active" in this context means that energy is required. A substance will flow in a certain direction, through diffusion, without having to provide additional energy. To force the substance in the opposite direction would require energy; the cell has to be "active" to achieve this, and this requires energy.
How is diffusion different from active transport?
active transport is different from diffusion. active transport has to do with the movement of chemical substance through a gradient of concentration. diffusion has to do with requiring the expenditure of energy
