What is the movement of chemical substances usually across the cell membrane againts a concentration gradient requires cells to energy?
active transport
The resistance to an ion's movement across a membrane is determined by?
ion channels within the membrane
The movement of a substance across a biological membrane against its concetration gradient with the help of energy input is?
facilitated diffusion....but im not 100% sooo....yeah good luck with that (:
The movement of water across a membrane is termed?
it is called osmosis and it is the net movement of water particles across a semi-permable membrane against the concentration gradient!
What does Chemiosmosis involves .?
The movement of hydrogen ions across a mitochondrial membrane.
When does movement of a substance across a cell membrane using chemical energy occur?
During osmosis and uptake of minerals.
What is facilitated diffusion across the phospholipid membrane?
Facilitated diffusion is the movement a substance from high concentration to low concentration across a membrane through a transporter protein or channel
The movement of water across a membrane is trem?
The movement of water across a membrane is called osmosis.
What movement do ion channels aid?
the movement of ions across a cell membrane.
In osmosis which membrane provides net movement of water without movement of NaCl?
Osmosis across a selectively permeable membrane allows water across but disallows other particles across the membrane.
What type of molecule movement consist on one way diffusion across a semi permeable membrane?
The movement of molecules across the semipermeable membrane follows the law of diffusion. Thus, the molecules of a substance move from their higher concentration towards their lower concentration by their own kinetic energy.
How do you use active transport in a sentence?
Active transport is the movement of a substance across a cell membrane from low to high concentration with the help of energy.
What is the movement of chemical substances usually across the cell membrane againts a concentration gradient requires cells to energy?
active transport
What is the transport of water across the cell membrane called?
Movement of water across a membrane is called OSMOSIS.
Whats the only substance that carries out osmosis?
The only substance that carries out osmosis is water. Osmosis is the movement of water through a semi-permeable membrane from a low concentration of solute to a high concentration of solute in the pursuit of equilibrium across the membrane.
What is the membrane said to be if a substance is able to diffuse across a membrane?
selectively permeable
If a substance is able to diffuse across a membrane then the membrane is said to be what?
selectively permeable
