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.
How is active transport different then osmosis?
Osmosis is the diffraction of water through a permeable membrane using no energy, whereas active transport is the moving of particles across a membrane against a concentration gradient. Basically, Osmosis moves water with no energy. Active transport moves particles, in general, with the use of chemical energy like ATP.
Where can you find a diagram to show diffusion?
Diffusion is the movement of molecules across a selectively permeable layer from an area of high concentration to an area of low concentration. In cells, this can happen without the use of energy from the cell. Only molecules of certain sizes and attributes can diffuse. Others may need to be facilitated or moved via active transport (using energy). See the 'Related Links' below for diagrams and pictures.
What does an Aerobe use as the final electron acceptor?
Aerobes use oxygen as the final electron acceptor in electron transport phosphorylation. The process that yields a final product called lactate fermentation.
What processes does not use ATP muscle contraction active transport heat production diffusion of oxygen cytoplasmic?
Diffusion of cytoplasmic oxygen.
What 2 transport processes use carrier proteins?
facillitated diffusion and active transport
Is diffusion an active transport?
no it is not because it does not require the use of ATP
Is facilitated diffusion an active transport?
no it is not because it does not require the use of ATP
What are ways for materials to move in and out of cells?
passive transport and active transport
What type of cellular transport requires a cell to use energy?
facilated diffusion cause when yer active you use energy
Does active transport use oxygen?
Active transport (or active uptake, as we learnt it ) is moving against the concentration gradient. This requires energy which is why the oxygen is needed (the oxygen producing energy through respiration). It is affected by the concentration of oxygen because the more oxygen, the more energy produced, the faster the process occurs. Diffusion is not affected by the concentration of oxygen because it does not require energy to occur.
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. 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 when there is no concentration gradient. Active transport requires energy to occur however, diffusion does not.
What requires the use of energy and the help of transport proteins to move a molecule across the cell membrane?
Facilitated diffusion
What process involves the use of specific carrier molecules?
two processes requiring the use of protein carrier molecules?
What are two forms of passive transport of a cell?
Two forms of passive transport (or transport not involving energy/ATP) are diffusion and facilitated diffusion. Another form is osmosis. Also keep in mind that passive transport is for smaller particles.
Is carrier proteins passive transport or active transport?
Carrier proteins can use active or passive transport depending on what type of carrier protein it is (meaning what the protein transports). The form of passive transport that they use is facilitated diffusion. An example of active transport is the Sodium Potassium pump. Active transport requires ATP. Facilitated diffusion is used to transport polar molecules and ions that cannot directly cross the cell membrane. Facilitated diffusion doesn't require energy.
