Molar concentration1.0Molar concentrationDepicted below is a cell membrane separating two closed compartments, each filled with one liter of H₂. Youadd one mole of each of the molecules as shown below. The molecule to which the membrane is most permeablediffuses across at a net rate of 0.5 moles/hour. Based on this information, answer the following questions.1.00₂Nat0.5-fructoseglycerolK+2. Graph the expected relative concentrations of each solute in the right hand compartment as a function of time.1Time in hoursNat1. Immediately after adding these solutes, will there be a netmovement of H₂O molecules across the membrane in onedirection? If so, in which direction and why?throughrightK+3. Finally, you add ATP to the left side compartment at the time indicated by the arrow below, and measureconcentration of Nat and K+ in the right side compartment. Your results are graphed below. Propose ahypothesis to explain the results you obtained in this experiment.2(10mgr1Time in hourscentrata-r211-X

The following table shows experimental results of the glucose transport rate, mM/sec, following facilitated diffusion by glucose carrier proteins. (Recall: the starting conc. L represents glucose added to one side of the membrane; distilled water, omM of glucose was added to the other side of the membrane). The rate of glucose transport was 0.0031 mm/sec with 8mM of glucose (run number 4, highlighted); the rate decreased to 0.0017 mM/sec with 10mM of glucose (run 5, highlighted). Why was the rate of glucose transport slower when the concentration gradient was increased?

A cell with a K+1 concentration of 0.3 eq/L is placed into a solution with a K+1 concentration of 0.2 eq/L. It is assumed that the K+1 can pass through the cell membrane (the K+1 transport protein is open). Answer the following true or false questions. 1. K+1 will diffuse through the membrane down its concentration gradient due to Kinetic Theory 2. Movement of a solute through the membrane is called dialysis 3. K+1 will move out of the cell
List the steps involved in neurotransmitter release starting with depolarization and ending with exoctosis. Include 1) the relevant channel and dynamics of the transmembrane domains and subunits; 2) ionic movements; 3) the various stages of the vesicles and the proteins involved as well as their configurations. There are 4 main steps that you should include.
