What is particle movement from an area of higher concentration to an area of lower concentration using a transport protein?
Diffusion. Diffusion is a process of passive transport in which molecules move from an area of higher concentration to one of lower concentration.
Is movement from high to low concentration active or passive?
During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.
How do you know if it’s active or passive transport?
In Active transport the molecules are moved across the cell membrane, pumping the molecules against the concentration gradient using ATP (energy). In Passive transport, the molecules are moved within and across the cell membrane and thus transporting it through the concentration gradient, without using ATP (energy).

| What is it? | Diffusion is a spontaneous movement of particles from an area of high concentration to an area of low concentration. (ex. tea flavoring moving from an area of high to low concentration in hot water.) |
What are the 3 differences between passive and active transport?
Active transport requires energy for the movement of molecules whereas passive transport does not require energy for the movement of molecules. In active transport, the molecules move against the concentration gradient whereas in passive transport, the molecules move along the concentration gradient.
What moves from high concentration to low concentration in osmosis?
1: Osmosis: In osmosis, water always moves from an area of higher water concentration to one of lower concentration. In this example, the solute cannot diffuse through the membrane, but the water can. Water has a concentration gradient in this system.
What is the movement of particles from higher concentration to lower concentration?
Diffusion is the movement of particles from areas of higher concentration to areas of lower concentration. It is a natural, random process. What type of transport goes from a lower concentration to higher concentration?
What is a concentration gradient in passive transport?
In passive transport, substances move from an area of higher concentration to an area of lower concentration. A physical space in which there is a single substance concentration range has a concentration gradient. Plasma membranes are asymmetric: the membrane’s interior is not identical to its exterior.
What do you mean by passive transport?
1.Process by which a cell takes in material by forming a vacuole around it. 2.The cell membrane forms around substance for example, how the amoeba gets its food. Passive Transport. 1.Particle movement from an area of higher concentration to an area of low concentration.
What do you mean by active transport?
1.Particle movement from an area of higher concentration to an area of low concentration 2.The movement of substances through the cell membrane without the use of cellular energy. Active Transport 1.Particle movement from an area of lower concentration toan area of higher concentration 2.
