Yes. Transport that goes down a concentration gradient is spontaneous and therefore does not require energy.
yes
Active transport requires energy and Passive transport requires no energy.Passive transport is a process which is carried out along the concentration gradient. For example, if the concentration of water is more outside the cell than inside, water will flow into the cell. Simply put, it is actually diffusion which occurs in passive transport and hence, no energy is required.Active transport, however, is carried out against the concentration gradient and hence requires energy. An example of active transport is the uptake of salt by cells through sodium pump.Active transport requires energy and moves particles up their concentration gradient. Passive transport doesn't require energy and moves particles down their concentration gradient.
Active Transpot. -Pumps -Endocytosis -Exocytosis Passive Transport - Diffusion -osmosis -Facilitated Diffusion active requires energy passive doesnt. active against concentration gradient, passive along concentration gradient.
When a region of higher concentration to a region of Lower concentration against the gradient which requires Energy is called Active Transport
active transport requires the use of energy aka ATP and is usually against the concentration gradient. passive transport does not require energy because it moves in response to the concentration gradient.
They move via passive transport. They move by diffusion. It's only active transport if A) the cell is too big or not fatty enough to move through the membrane and needs help or B) is making the molecules move unnaturally (low to high). Osmosis is also passive transport, but only is used when referring to the movement of water.
A kind of transport by which ions or molecules move along a concentration gradient, which meansmovement from an area of higher concentration to an area of lower concentration.
The inter-membranous transport occurs in two ways: 1) Active Transport: occurs against the concentration gradient, Expenditure of energy occurs. 2) Passive transport: Refers to phenomena wherein transfer occurs along the concentration gradient i.e. from high concentration to low concentration, without any expenditure of energy.

Any form of transport that does not require a form of energy, which means that it happens along a concentration gradient (from an area of high to low concentration) and across a selectively permeable membrane (Osmosis)

It is a type of passive diffusion, as the water travels along a concentration gradiant. As opposed to active transport, where the substances can pass against a concentration gradiant.

The process by which molecules such as glucose are moved into cells along their concentration gradient with the help of membrane bound carrier proteins is called facilitated diffusion. Facilitated transport is passive and does not directly require chemical energy from ATP.
In biology, diffusion is the passive movement of molecules or particles along a concentration gradient, or from regions of higher to regions of lower concentration. Diffusion is the free movement of particles in a liquid or gas down a concentration gradient.
