Which type of transporters is used to move a molecule from a region of low concentration traction to a region of high concentration?
protein molecules in the cell membrane
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
What type of molecular movement is it if movement of molecules is against the concentration gradient from low to high through protein pumps?
Active Transport
What process transport pyruvic acid across the mitochondrial membrane from a high concentration to low concentration?
Active transport - since pyruvate is ionic is must use protein transporters, and ATP is required
What happens when there is a low water concentration outside of a cell?
The water inside the cell goes with the low concentration to reach equilibrium.
Is a protein osmosis?
No because osmosis is the diffusion of water where water with high concentration moves to water with low concentration, therefore it has nothing to do with protein.
What is hypo proteinemia?
an abnormally low concentration of protein in the blood. and its hypoproteinemia
Which type of transporters is used to move a molecule from a region of low concentration traction to a region of high concentration?
protein molecules in the cell membrane
What are some characteristics of facilitated diffusion?
The substances are moving from areas of high concentration to areas of low concentration with the help of a protein channel.
Does osmosis require protein?
Nope! Osmosis is simply the movement of H2O over a membrane from high concentration to low concentration. It's a form of passive diffusion!
What is the salt effect?
the low concentration of salt increases the protein solubility on aqueous solution,known as salting in effect
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
When molecules move down the concentration gradient it means they are moving from high to low or low to high?
An area of higher concentration to an area of lower concentration.
What type of molecular movement is it if movement of molecules is against the concentration gradient from low to high through protein pumps?
Active Transport
What process transport pyruvic acid across the mitochondrial membrane from a high concentration to low concentration?
Active transport - since pyruvate is ionic is must use protein transporters, and ATP is required
How would sugar enter a cell that has a low concentration of particles get through a cell membrane and into a cell wall?
By diffusing across the protein membrane.
Explain why osmosis is different from diffusion?
Osmosis is specifically the movement of water from an area of high water concentration to an area of low water concentration across a small semipermeable membrane. Diffusion is the movement of other particles from an area of high concentration to an area of low concentration, either directly across the phospholipid bilayer or through protein channels imbedded in the phospholipid bilayer
