What cellular process causes the movement of the oxygen into the cells from the blood?
Pizza
What is an example of active transport using physiological processes in the human body?
diffusion occurs naturally facilitated diffusion and active transport need energy
What is the name of the molecule movement when sugar has dissolved into water?
diffusion
What is a active transport?
Active transport is when energy is spent to moving a nutrient from Point A to Point B. It is the opposite of Diffusion.
What is the term for the movement of molecules from an area of lower concentration to an area of higher concentration?
If it is the movement of molecules then it is diffusion. If it the movement of water then it is osmosis
What are the three types of movements?
There are three types of cellular movement. These are active transport, diffusion, and osmosis. All are very important in growth and movement.
What cellular process causes the movement of the oxygen into the cells from the blood?
Pizza
What is the movement of materials through a cell membrane?
Movement of substances into and out of cells include passive mechanisms that do not require cellular energy (diffusion, facilitated diffusion, osmosis, and filtration) and active mechanisms that use cellular energy (active transport, endocytosis,and exocytosis).
The movement of molecule down a concentration gradient through transport proteins in the cell membrane is a type of?
facilitated diffusion.
What is passive cellular transport?
Diffusion and osmosis ( movement of molecules from higher concentration to lower concentration until evenly spread.)
How diffuison works?
The random movement of molecules from an area where there is relatively more of them into an area where there are fewer is called diffusion. Diffusion OS one type of cellular passive transport.
What isit called when a molecule moves across a semipermeable membrane into a region of higher concentration?
When a molecule moves to a higher concentration it needs help of a pump. We call this facilitated diffusion. Osmosis only deals with the movement of water.
What type of transport is used to move a molecule from a region of low concentration to a region to a high concentration?
active transport
What is an example of active transport using physiological processes in the human body?
diffusion occurs naturally facilitated diffusion and active transport need energy
What energy is required for passive transport?
By definition, passive transport on a cellular level requires no energy other than some sort of gradient, whether of the molecule in question, or another whose movement across the membrane can be linked to the one of interest.
What are the types of movement through a membrane?
Osmosis, diffusion, facilitated diffusion, active transport
What is the random movement of molecules and ions down their concentration gradient called?
The random movement of molecules and ions down their concentration gradient (meaning from an area of high concentration to an area of low concentration) is called simple diffusion. Simple diffusion is related to the magnitude of driving force, permeability of the membrane, and surface area.
