an essay about the digestive system.

Your essay should contain some physiology and some appropriate chemistry. It should explain how the anatomical structures of the digestive system are well suited to perform the functions that they do. Your essay could include a discussion of the role of the accessory organs in digestion. Your essay could discuss the chemical reactions that constitute the breakdown of complex molecules into simple molecules. It could follow in detail how the digestion and absorption of protein or carbohydrate or lipid occurs (or all three in less detail). It may also discuss how the processes of digestion are controlled.

Solute concentration is defined as the amount of the solute present in a given volume of solution. The concentrations of solutes in a solution are key to their ability to produce physiological actions. One measure of the amount of a substance is its mass expressed in grams. The unit of volume in the metric system is a liter (L). The concentration of a solute in a solution can then be expressed as the number of grams of a substance present in any one liter of solution (g/L). A comparison of the concentrations of two different substances on the basis of the number of grams per liter of solution does not directly indicate how many molecules of each substance are present. Thus, concentrations are expressed based upon the number of solute molecules in solution, using a measure called the molecular weight. One mole (mol) of a compound is the amount of the compound in grams equal to its molecular weight. One mole of solute dissolved in a liter of water is known as a 1 molar solution (1 mol/L).

To practice calculating molecular weight and examining the relationship between volume and solute variations, complete the following exercises.

First, calculate the molarity of a 2 L solution with five different amounts of solute (20, 40, 60, 80, and 100 g). The solute for this activity is glucose with a molecular weight of 180 daltons. Round all of your calculations to the nearest hundredth for credit.

Then plot each of these data points by clicking to select the amount of solute from the "Tools" section at right and then clicking on the exact location on the graph corresponding to your calculations. If you wish to change your data point on the graph after first placement, you can double click the data point and adjust the values.

Second, calculate the molarity for five different solution volumes (0.5, 1.0, 1.5, 2.0, and 2.5 L) each with 80 grams of solute. The solute for this activity is glucose with a molecular weight of 180 daltons. Round all of your calculations to the nearest hundredth for credit.

Then plot each of these data points by clicking to select the final total volume from the "Tools" section at right and then clicking on the exact location on the graph corresponding to your calculations. If you wish to change your data point on the graph after first placement, you can double click the data point and adjust the values.
