Substances can be moved from a region of lower concentration to a region of higher concentration, against the concentration gradient. Hence, it is useful for plants for absorbing mineral salts from the soil, reabsorption of useful substances back into the bloodstream in the kidney and such.

What process requires cells to expend energy in the form of ATP?

Active transport processes, such as the sodium-potassium pump, require cells to expend energy in the form of ATP. The energy from ATP is needed to move molecules or ions against their concentration gradient, from an area of lower concentration to an area of higher concentration.


What is the importance of Active Transport in living organisms?

Active transport is important in living organisms because it allows them to transport molecules against their concentration gradient, from an area of low concentration to an area of high concentration. This process requires energy to be expended by the cell, usually in the form of ATP. Active transport is crucial for maintaining proper ion concentrations and nutrient uptake in cells, thus enabling cellular functions and overall organismal survival.


What are facts about passive transport?

The transport of molecules across the plasma membrane of a living cell by a process that involves a specific transmembrane carrier


What is the process in which a molecule passes from an area of low concentration to an area of high concentration?

Active transport.Substances naturally (passively) spread out evenly. This means there is a net movement from higher to lower concentrations. The process is diffusion, and no energy input is required.For a substance to move the other way (up or against the concentration gradient) a supply of energy is required. This process (active transport) will not happen in non-living systems, but cells can supply energy, for example in the form of ATP.True


Do aquaporins participate in active transport in a cell?

No, aquaporin's do not need a living cell in order to function. Aquaporin's are water channels that permit water channels to cross membranes.

Higher concentration is maintained by the process of?

active transport, where energy is used to move molecules against their concentration gradient to maintain a higher concentration in a particular area. This process is essential for cell functioning and maintaining homeostasis in living organisms.

Is active transport vital to living organisms?

Yes it is. There are many examples of active transport in living organisms.1. Plant roots absorb minerals from the soil water surrounding them by active transport.2. In the Human body, the glucose formed during digestion passes from the small intestine into the blood stream by active transport.

What is the significance of active transport in a living cell?

It maintains the cell's chemical environment.


What is significance of active transport of the survival of a cell?

Active transport requires the expenditure of energy by the cells. It is an uphill movement of a substance through a living cell membrane. Adenosine triphosphate or ATP is a chemical substance that gives the energy required for the active transport process. ATP is produced in the mitochondria using energy from nutrients and is capable of releasing that energy to do work in the cell. There is a breakdown of APT and a use of energy that makes this process possible. Cellular energy is required to move substances from a low concentration to a high concentration. Because the formation and breakdown of ATP requires complex cellular activity, active transport mechanisms can take place only through living membranes.


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.

Why is it impossible for the water conducting cells of xylem to carry on active transport?

Water conducting cells in xylem lack the organelles necessary for active transport functions, such as mitochondria and endoplasmic reticulum. Their main function is to conduct water and minerals through passive processes like transpiration and cohesion-tension. Additionally, active transport requires energy input, which the non-living xylem cells cannot generate.


Differences between diffusion and active transport?

Diffusion is the passive movement of molecules from an area of high concentration to an area of low concentration, while active transport requires energy to move molecules against their concentration gradient, from an area of low concentration to an area of high concentration. Active transport is selective, meaning it can move specific molecules, whereas diffusion is non-selective.
