You add 1 tsp. of sugar to a warm water solution and wait for the sugar molecules to diffuse acrossa screen gradient. You then add 1 tsp. of sugar to a cold-water solution. What will happen to therate of diffusion of the cold water solution, when compared to the warm water solution rate?O It will decrease (slow downO It will stay the sameO It will increase (speed up)

Movement of substances occurs by active or passive transport mechanisms.

In the diffusion of dye in water experiment, what variable did we test for that affected rate of diffusion? How did it affect rate of diffusion? a viscosity; higher viscosity results in slower rate of diffusion b temperature; higher temperature results in slower rate of diffusion c viscosity; higher viscosity results in faster rate of diffusion d temperature; higher temperature results in faster rate of diffusion
Here is a chloride cell in the gill epithelium of a fish. For reference, NKA = Na+/K+ ATPaseNKCC = Na+/K+/Cl- cotransporter. The NKCC (Na+ K+ Cl- cotransporter) moves Cl- into the cell against its concentration gradient. What type of transport does NKCC carry out?A. passive diffusionB. facilitated diffusionC. secondary active transportD. primary active transport
2. If there were 0 glucose carrier proteins inserted in the membrane, would diffusion of glucose occur? Why or why not? Number of glucose carrier proteins in membrane Glucose diffusion rate (mM/sec) 300 0.0015 500 0.0023 700 0.0031 900 0.0040
So I know that Dapagliflozin is a inhibitor of the sodium glucose cotransporter so does Dapagliflozin cause glucose to just stay in the cell or does it cause glucose to exit the cell? Also if does cause glucose to exit the cell is this a passive or active process. I would think that it would be passive since the glucose is going from high to low?? So is it faciliated passive diffusion?? Please help I am not sure if I am on the right track or not I could be totally wrong so please correct me.

A driving ion moving through a membrane channel in one direction gives energy to actively transport another molecule in the opposite direction. What is this process called? a. facilitated diffusion b. antiport transport c. symport transport d. primary active transport pump e. contransport
Which of the following methods of transport is being used to transfer the substance into the cell in the accompanying graph? a. diffusion down a concentration gradient b. osmosis c. facilitated diffusion d. active transport e. vesicular transport f. It is impossible to tell with the information provided.
A blood cell with a 2% internal solute concentration is placed in a solution that has a 0.2% solute concentration. The solute is impermeable to the plasma membrane. How would you classify the solution compared to the cell – hypotonic, hypertonic or isotonic? Why? (2 pts.) B) Will the solutes move across the membrane? Why or why not? C) What type of transport would occur in this situation – diffusion, facilitated diffusion, osmosis, active transport or bulk transport. Explain. D) What would happen if the cell began to produce a new membrane protein that allowed the solutes to freely move in across the membrane? ould this change your answer to Part C? Explain.
secondary active transport depends on which of the following principals a. sodium is pumped pout of the cells against a concentration gradient by [primary active transport b. sodium moves out the cells with a concentration gradient c. primary active transport is necessary to pump sodium into the cell from higher to lower concentration d. diffusion causes sodium to move our of the cell
Thinking back to the "effect of concentration" lab, what did your data indicate? The concentration gradient does not have an effect on the rate of diffusion. An increase in the concentration gradient will cause the rate of diffusion to decrease. An increase in the concentration gradient will cause the rate of diffusion to increase .
The membrane of most cells, including neurons, contains passive, open, K' leak channels. Given the normal K' concentrations and the resultant concentration gradient, which direction would K' be expected to move (diffuse) through these leak channels? Select one: 1/into the cell 2/out of the cell
