What motion of particles across a membrane requires energy?
Movement across a membrane that does require energy is called active transport.
Facilitated diffusion across a biological membrane requires what?
transport proteins
What is the process that utilizes a carrier to move materials across the plasma membrane in the direction of the concentration gradient that does not use ATP?
Active Transport
The process where a nonpolar molecule can just passively get across a membrane is called?
facilitated diffusion
What is the process that utilizes a carrier to move marerials across the plasma membrane in the direction of the concentration?
Diffusion is what carries materials across the plasma membrane. The diffusion cannot be moved across water.
Is diffusion of molecules across the cell membrane the most complex type of active?
No, diffusion of molecules across a cell membrane is a passive process, not active, and arguably the least complex.
Which process requires cellular energy to move molecules across the cell membrane from a region of lower concentrations to a region of higher concentration?
You are describing active diffusion.
What involves the movement of solutes across a selectively permeable membrane by the process of difussion?
facilatated diffusion
Ions diffuse across membranes down their what?
Its an active transport and use sodium channel generally _____ Diffusion is itself a pathway of travel across a cell membrane. Diffusion can be "simple diffusion" which is simply an ion moving across the membrane anywhere, or "fascilitated diffusion", where an ion moves across the membrane in a specific channel. Either way, diffusion involves the movement of that ion along its concentration gradient and requires no energy. Active transport is not the same as diffusion. Active transport requires energy.
What happens during the process of faciltated diffusion?
An Integral Membrane Protein Assists A Specific Substances Across The Membrane.
What is a transport process by which gases move through a membrane?
Simple Diffusion
What is the process When proteins help molecules move across the membrane is called?
when proteins help molecules move across the membrane, it it called Facilitated Diffusion
