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
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 transport of water across the cell membrane called?
Movement of water across a membrane is called OSMOSIS.
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
