Step by step
Solved in 2 steps
- create a flow chart or diagram to illustrate the digestion and absorption of carbohydrates. The starting carbohydrate molecules are starch, sucrose, lactose, glycogen, and cellulose. What will happen to these carbohydrates once we ingest them? Include the following from your flow chart or diagram: 1) the location or site where the digestion or absorption occurs 2) the enzymes 3) the products generated at each site or locationWhy can't humans digest cellulose while ruminants can? What is the difference between the two organisms?What is the final product of digestion of all carbohydrates? Why do some people need to take Lactase with milk products?
- Where does digestion of starch begin in human body?Describe the biological basis of inability of humans to digest celluloseSuppose that you perform an experiment to observe the effect of temperature and pH on the enzymatic activity of salivary amylase using the Iodine test, and starch as the substrate. Complete the table below: Temperature (°C) Color of solution Rank (1 - greatest digestion and 3 - least digestion) with I2 4 37 100 pH Color of solution Rank (1 - greatest digestion and 3 -least digestion) with I2 4 7 10
- Gram for gram, fatty acids provide more energy than carbohydrates. For this reason, triacylglycerols were evolutionarily selected as the main energy storage molecule over glycogen. 1) In a sentence or two, explain why fatty acids are capable of providing more energy than carbohydrates. BE SPECIFIC. 2) The answer to PART 1 actually creates complications in how lipids are digested. Why is this? 3) Now consider the fatty acid stearate. Stearate contains a total of 18 carbon (C) atoms and, when it is oxidized, a TOTAL of nine acetyl CoA molecules are produced. As you know, every molecule of glucose contains a total of six C atoms, so three glucose molecules have the equivalent number of carbons as one stearte. A) How many acetyl CoA molecules are produced when three glucose molecules are oxidized? B) Considering ALL of the above information, please explain why three glucose molecules DO NOT provide the same amount of energy as one stearate molecule. For full credit, link your answer to…Why are people who consume many of their carbohydrates in the form of high-fructose corn syrup (HFCS) more apt to overeat than people who consume carbohydrates in the form of starches?
