D. Analyze the following diagrams to answer the questions that follow. Below is an example of dehydration synthesis. In dehydration synthesis, a hydrogen atom from one molecule joins with a hydroxyl group (-OH) from another molecule to form water, leaving two molecules bonded to the same oxygen atom. For example, when glucose and fructose combine by dehydration synthesis, they form sucrose and water. Below is an example of hydrolysis. Complex organic molecules are broken down by the addition of the components of water - H+ and OH-. 1. What are the reactants of the dehydration synthesis reaction? 2. What are the products of the hydrolysis reaction? 3. How are these two reactions related?

Part 2 - Use the notes from the Dehydration Synthesis and Hydrolysis video to answer the following questions regarding the figure above. 1. What kind of monomers are A and B? 2. Which direction is a hydrolysis reaction occurring? Is a water molecule being produced or consumed? 3. Which direction is a dehydration reaction occurring? Is a water molecule being produced or consumed? 4. What kind of macromolecule is E?

Dehydration Synthesis and Hydrolysis: Carbohydrates, proteins, and lipids are all synthesized and broken down by the same types of reactions. In dehydration synthesis, a hydrogen ion (H+) from one molecule joins with a hydroxyl group (OH-) from another molecule to form water (H2O), leaving the two molecules bonded to the same oxygen atom. For example, when two molecules of glucose are joined by dehydration synthesis, they form maltose and water (see below). In hydrolysis, complex organic molecules are broken down by the addition of the components of water - H+ and OH-. Both dehydration synthesis and hydrolysis require certain conditions of pH and temperature and the presence of particular enzymes. Briefly compare and contrast the dehydration synthesis and hydrolysis reactions.
