Three ways that substances can move into and out of a cell?
Substances can move into and out of a cell through passive diffusion, facilitated diffusion, and active transport. In passive diffusion, molecules move from an area of high concentration to low concentration. Facilitated diffusion involves the use of carrier proteins to help molecules pass through the cell membrane. Active transport requires energy to move molecules against their concentration gradient.
How do substances like co2 and water move in and out of the cell?
By the process of diffusion and osmosis.
How do nutrients first enter a cell?
nutrient are broken down before entering the cell.small parts of nutrients are taken inside a cell be diffusion and passive transport. there is no energy usage this kind of transport. but there are some big molecules that can not enter cell membrane. so there are taken by active transport.(there is a energy usage in active transport).
Is diffusiona type of passive transport or active transport?
Passive transport is where materials are transported across a membrane without the use of stored energy. Active transport is where materials are transported across a membrane using ATP, or another source of stored cellular energy. Diffusion is where solutes flow across a membrane in response to a concentration gradient, and requires no energy input to occur. Therefore, diffusion is a form of passive transport.
Does facilitated diffusion require the Cell to use energy?
No, there is no ATP used in facilitated diffusion, because it is a form of passive transport. It only differs from normal diffusion in that it uses transport proteins to move larger or more polar molecules across the membrane of the cell.
What processes does not use ATP muscle contraction active transport heat production diffusion of oxygen cytoplasmic?
Diffusion of cytoplasmic oxygen.
Is diffusion an active transport?
no it is not because it does not require the use of ATP
Is oxygen a passive transport or an active transport?
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.
Is facilitated diffusion an active transport?
no it is not because it does not require the use of ATP
How can active transport differ from passive transport?
Active transport requires energy input to move molecules against their concentration gradient, while passive transport does not require energy and moves molecules along their concentration gradient. Active transport usually involves the use of transport proteins, such as pumps or carriers, while passive transport relies on diffusion or facilitated diffusion.
What 2 transport processes use carrier proteins?
Two transport processes that use carrier proteins are facilitated diffusion and active transport. In facilitated diffusion, carrier proteins help move molecules across the cell membrane down their concentration gradient, while in active transport, carrier proteins help move molecules against their concentration gradient by using energy.
What type of cellular transport requires a cell to use energy?
facilated diffusion cause when yer active you use energy
What requires the use of energy and the help of transport proteins to move a molecule across the cell membrane?
Facilitated diffusion
Active transport counters the process of diffusion?
Yes, active transport is a process in which cells use energy to move molecules against their concentration gradient, whereas diffusion is a passive process where molecules move from an area of high concentration to an area of low concentration. Active transport allows cells to transport molecules against their concentration gradient, which is opposite to the direction of diffusion.
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.
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.

Are diffusion and osmosis two types of active transport?
No, diffusion and osmosis are passive transport processes that do not require energy input from the cell. Active transport, on the other hand, requires the cell to use energy to move molecules across the cell membrane against their concentration gradient.
