A time period in which a firing cell can not fire again. Compare tight junctions and gap junctions and their functions. A tight junction is a secretion of cells that blocks intercellular movement of fluids. A gap junction is a group of proteins that penetrate the membranes of adjacent cells and provide a channel for the movement of small molecules between the cells. Match the following with all possible correct answers.
Some individual moieties are essential in the diet.
Solution A is on one side of the membrane and solution B is on the other. A has more water B will be more negative 14. Test the rate of conversion of the substrate with different substrate concentrations. A non-competitive inhibitor will produce a maximum intitial rate that is lower than the control no matter what the substrate concentration. A competitive inhibitor will produce a slower rate of initial action that will approach the control maximum as the substrate concentration is increased.
