Active transport is a function of the cell membrane.

∙ 13y agoIn the human body, active transport takes place in the small intestine during digestion of food. The kidneys use active transport to move urea and nitrogen from the blood. low concentration of urea in the blood to a higher concentration in the kidneys.

∙ 12y agoto move the good stuff out of our food..
you see, in the digestive system the good stuff in our food is in an area of low concentration, so if we wanna get it into our blood streem we've got to move it to a higher concentration, thus moving against the concentration gradient..
that's why we need energy in active transport to move stuff...

The movement of substances across the cell membrane that requires the cell to use energy?
It's called active transport. When talking about the cell, it is usually bigger substances that use passages in the cell membrane to access the inner part of the cell, and they need energy to get there. The opposite; passive transport or diffusion, is the movement of dissolved materials through a cell membrane without the use of cellular energy. THis happens with smaller substances.
Why do cells need to perform active transport?
Cells need active transport to regulate their internal environment. The ability of a cell to regulate its internal environment is important because it allows the cell to add substrates to reactions that are necessary for life. Primary active transport (the movement of molecules against their electrochemical gradient) helps to power secondary active transport (or co-transport) which is the transport of an ion/molecule against its electrochemical gradient, in company with an ion/molecule being transported with its electrochemical gradient.
How are diffusion and active transport different?
There are two types of diffusion. Facilitated and non facilitated. Diffusion occurs when there is a concentration gradient. That is, when an area has more concentration than the other area. Diffusion is used to transfer particles from one place to another. Active transport is used to transfer particles, usually occurring against a concentration gradient. Active transport requires energy to occur however, diffusion does not. There are two types of diffusion. Facilitated and non facilitated. Diffusion occurs when there is a concentration gradient. That is, when an area has more concentration than the other area. Diffusion is used to transfer particles from one place to another. Active transport is used to transfer particles when there is no concentration gradient. Active transport requires energy to occur however, diffusion does not.
What part of a cell controls substances moving in and out?
The cell membrane is reposnible for allowing what substances can enter and leave a cell, this happens by different methods of transport for instance "active transport" in plants. The phospholipid bilayer containing cholesterol, proteins and carbohydrates, also helps in allowing which substances to pass.
What is the process that allows a substance to enter and leave the cell?
The cell has two ways of "eating" substances. The first is active transport. This is when the cell engulfs the food molecule or substance and the food becomes part of the cell. The second way is called diffusion. Substances that are outside the cell, protein for example, are so small that they can move through the cell's membrane without any trouble.
What cell part transports energy?
The Active transport
where does active transport takes place which part of the cell?
Active transport takes place in the small intestine, where nutrients are absorbed from the intestine and into the bloodstream. More specifically, it is the structures known as villi that contain the protein receptors necessary for active transport to take place. The process also happens in the nephrons of the kidneys, where glucose and water/ions are selectively reabsorbed back into the bloodstream.
Is diffusion part of an active transport?
No, diffusion is where particles flow in order to be equal, whereas active transport uses ATP to move them through a cell membrane.

Are protein part of cell membranes and store energy?
no proteins do not store energy they help active transport
Which part of the cell surrounds the cell and allows molecules in and?
The cell membrane is the thing that surrounds the cell. The cell membrane contains proteins that allow active transport of molecules in and out of the cell.
What kind of molecules are moved in active transport?
Active transport requires energy, unlike passive transport. The carrier proteins in active transport act as a "pump" ( fueled by ATP) to carry/attach themselfves to useful proteins for the cell.
What part of cells transport energy?
The Active transport
Which part of the cell surrounds the cell and allows molecules in and out this cell part also has holes in it and is said to be semi-permeable?
The cell membrane is the thing that surrounds the cell. The cell membrane contains proteins that allow active transport of molecules in and out of the cell.
What are passive transport active transport and endocytosis?
These are three different ways that cells have to get things in and out of the cell. Passive transport is movement without the use of energy, active transport requires energy.Active transport requires energy since the molecules are going toward a region that has a higher concentration of that molecule. The cell is 'stuffing' more into itself.Endocytosis means to 'take into the cell'. Usually this a larger molecule and cell must wrap part of itself around the molecule and then can bring it inside. This is a type of phagocytosis (cell eating).This requires energy as well.

Is mineral movement into plant root part of an active transport or passive transport?
Both
