After lipids are digested and enter absorptive cells, identify which lipids enter capillaries (water-soluble) and which are absorbed into lacteals (fat-soluble).
You eat spaghetti with tomato sauce, peas, and Parmesan cheese. Describe the path through each organ of the digestive system this meal takes, describing how EACH of the FOUR BIOMOLECULES of the meal is digested and absorbed. Discuss all of the organs and enzymes involved.
The digestion of lipids is more complicated than the digestion of carbohydrates and proteins.
In a few short sentences, explain what the complication is and describe one or two ways that the body gets around the issue.

What are the difference(s) between simple and complex carbohydrate? Give an example of each types of simple and complex carbohydrate. What are the main functions of carbohydrate in the body? Briefly list the steps of carbohydrate digestion from the mouth to the large intestine.arrow_forwardThere are several processes that take place from the moment food enters our mouth until it is completely digested and used for energy. Using approximately 400-500 words, describe in detail and in order of process the mechanical (stomach and intestine)and chemical (gastric acid and enzymes) digestion of eating a grilled chicken sandwich with mayonnaise, lettuce, and tomatoes. Note what role the pancreas, gallbladder, and liver play in digestion of the ingredients? From what ingredients is your body deriving its energy and how many basic calories from the macronutrients ingested? Include at least two scholarly references (using APA formatting and style) to guide your answers (note that you can use your textbook as one of your references).arrow_forward

The goal is to get to a point where there are only amino acids(from proteins), fatty acids (from lipids), and glucose (from starch). Enzymes are only part of chemical digestion.

Lastly describe what glucose, amino acids, and fatty acids will be used once they are absorbed into the bloodstream.arrow_forward
