What else can I help you with?
The movement of relatively large particles across a plasma membrane via transport proteins?
... is called "facilitated diffusion".
Is a primary transport the passive movement of large particles across the membrane?
No, primary transport involves the active movement of ions or molecules across a membrane against their concentration gradient, using energy typically derived from ATP. In contrast, the passive movement of large particles across the membrane is known as facilitated diffusion, which does not require energy and occurs through specific transport proteins. Thus, primary transport is an active process, while passive movement relies on concentration gradients.
What is the movement of particles diffusion osmosis or active transport?
Active transport is the movement of particles across a cell membrane against the concentration gradient with the help of energy. Diffusion is the movement of particles from an area of high concentration to an area of low concentration, and osmosis is the movement of water molecules across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.
What motion of particles across a membrane requires energy?
Movement across a membrane that does require energy is called active transport.
What is the difference between passive and active transport across the plasma membrane?
Active transport is ATP dependent, whereas passive transport uses only the kinetic energy of the particles for movement across the plasma membrane- mastering A and P homework-
What is the movement of particles in passive?
In passive transport, particles move across a membrane from an area of higher concentration to an area of lower concentration without the input of energy. This movement is driven by the concentration gradient and does not require the use of transport proteins. Examples include diffusion and osmosis.
Diffusion and osmosis are forms of what?
Diffusion and osmosis are forms of passive transport, which is the movement of particles across a membrane without requiring energy input from the cell.
What does a passive transport and an active transport have in common?
Movement of particles .
How do particles get in and out of the plasma membrane?
The movement is random, but there is a net movement from regions where there are lots of particles to ones where there are fewer particles.
Does passive transport require ATP for the movement of molecules across the cell membrane?
No, passive transport does not require ATP for the movement of molecules across the cell membrane.
What is the movement of water across a membrane?
Active transport
What is the movement of water across the membrane?
