Why does active transport happen?

Active transport requires energy because you are going against a gradient. Active transportation moving from low to high concentration, while passive transportation such as osmosis and diffusion go from high to low concentration. One example of passive transportation is a river. Floating downstream does not require any energy. You are simply moving with the gradient. If you wanted to go upstream, you would have to paddle. This requires an input of energy similar to active transport.


Can passive transport occur in a dead cell?

Diffusion does occur whenever molecular movement is possible. An organism lives because it is able to establish its own equilibria that are different from the random chaos that is nature's equilibrium. After death, any particle that is not in a state of nature's equilibrium will trend to that state until it is achieved. Restated, everything trends towards nature's equilibrium unless some energy is expended to do otherwise. All energy production ceases soon after death. This is when everything trends back to "nature's equilibrium." Active transport occurs in live organisms as energy is required to move molecules against "nature's equilibrium." After death, energy production soon stops. When it does, so does active transport.


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


What must happen when a concentration gradient is eliminated?

When a concentration gradient is eliminated, there will be no difference in the concentration of a substance across a region. This can lead to equilibrium, where molecules are evenly distributed, or in the case of active transport, energy may be required to maintain the concentration gradient.


Can an earthquake happen in Ohio?

An earthquake can happen anywhere. But some places are more active than others.

What would happen to a cell if treated with an active transport inhibitor?

If a cell is treated with an active transport inhibitor, it will be unable to efficiently move molecules across its membrane against a concentration gradient. This can lead to disruptions in key cellular processes that rely on active transport, such as nutrient uptake, waste removal, and maintaining ion gradients. Ultimately, the cell's ability to function properly may be compromised.


What are three ways molecules can cross the cell membrane?

Molecules can cross the cell membrane through simple diffusion, facilitated diffusion via transporter proteins, and active transport using energy to move molecules against their concentration gradient.

What role does a cellular membrane play in active transport?

Active transport is the name given to the process of using energy to move substances into cells against what would happen without the expending of energy. Think of an island you want to visit. It is too far away to have a bridge so t is required to expend more energy than usual to get there--either by boat or plane, for example. Osmosis or diffusion account for movement of substance within another substance or across a membrane. It could be argued that there is energy involved in these movements, but no ATP is used. Active transport requires either ATP or electrochemical potential for movement. Sometimes, active transport moves substances against a concentration gradient. In the case of roots, the concentration of "fertilizer" or ions in the soil may be far less than in the tissues of the roots, yet active transport allows more ions to enter the roots. This is the method of obtaining glucose, for example, from your intestinal contents in the cells of the intestine. Active transport is like a ferry, but you have to pay the ferryman to gain passage.

What will happen if transport layer is removed from tcp protocol stack?

many things happen.....


If you remove a plant from the soil what will happen?

It can result in erosion, nutrient depletion, and desertification.


Osmosis does it need energy?

No, actually diffusion is a kind of passive transport, and osmosis is a kind of diffusion. Any passive transport can happen without energy (contrary to active transport). Since, all the things you listed were passive transport, they happen down the concentration gradient and need no ATP.
