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.
What is the movement of materials across a membrane that requires energy input called?
Active transport requires energy and proteins to move the materials across the cell membrane. This is in contrast to osmosis, which doesn't require energy to move the material.
The use of energy to move substances across a cell membrane describes?
Active Transport
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
Movement of water across a cell membrane?
they pass through channels in the cell membrane
What is the movement of water across a membrane?
Active transport
What is the movement of water across the membrane?
Active transport
If a substance is unable to diffuse across a membrane we say the membrane is?
osmotically active
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.
What ways of moving molecules across a membrane requires energy?
Active Transport.
What is it called when molecules uses energy to move across a semipermeable membrane?
Active transport
What is the process of moving materials across membrane with energy?
active transport
What is the movement of materials across a membrane that requires energy input called?
Active transport requires energy and proteins to move the materials across the cell membrane. This is in contrast to osmosis, which doesn't require energy to move the material.
What happens to the resting membrane potential if ATP was depleted in a nerve cell?
All active transportation of ions would stop and ions would be allowed to run down their concentration gradients, eventually reaching equilibrium. At this stage there would be no more electrochemical potential difference across the cell membrane.
What moves marerials across the plasma membrane in the direction of the concentration?
Active transportation is the material that across plasma membrane. This makes it flow one way.
What motion of particles across a membrane requires energy?
Movement across a membrane that does require energy is called active transport.
The use of energy to move substances across a cell membrane describes?
Active Transport
