Be sure to label the new solutions in each condition, draw the changes (if predicted) in cell shape/volume, and clearly use arrows to indicate the movement of water relative to the cell. Please start with a red blood cell in an isotonic solution (Figure D) and show what happens to cell shape and water movement when NaCl (remember that the membrane is permeable to neither of these ions) (Figure E) or urea (a permeable ion) (Figure F).23.Summarize the steps that occur to set up secondary transport (co-transport) and during co-transport. Practice by drawing in circled numbers in the images below to match the steps I have summarized below. [Gluc [Na] low Na high Na ATP 1. Three Na' ions inside the cell move OUT of the cell, across the Na*K* pump, from a low to a high concentration (AGAINST their concentration gradient). This requires the energy of ATP. This sets up the concentration gradient needed in the next step (the next step requires a low Nation concentration INSIDE the cell) 2. Nations in the interstitial fluid = extracellular fluid (fluid surrounding the cell) move INTO the cell, across a co-transport protein. The ions move from a high to a low concentration (DOWN their concentration gradient). This RELEASES energy. This energy is used in the next step. 3. Glucose in the interstitial fluid moves INTO the cell, across a co-transport protein, from a low to a high concentration (AGAINST their concentration…Match the transport mechanisms with their descriptions.
