Solved in 2 steps
- Calculate the total ATP produced by the complete oxidation of a triglyceride composed of three palmitic acids in the liver. Be sure to indicate the specific steps involved and their corresponding ATP (or ATP equivalent).Glutathione is an important intracellular thiol. List fivefunctions of glutathione in the bodyEfficiency of ATP Production in Muscle: The transformation of glucose to lactate in myocytes releases only about 7% of the free energy released when glucose is completely oxidized to CO2 and H2O. Does this mean that anaerobic glycolysis in muscle is a wasteful use of glucose? Explain.
- Determine the number of moles of ATP that can be generated from the fatty acids in 1 mol of tristearin, a triacylglycerol composed of glycerol esterified to three stearic acid molecules. What is the fate of the glycerol product in the body?Activity of Salivary Amylase: 1. Is there a difference in the time to dissolve the small and larger biscuit/cracker? Explain. 2. Explain your observations with the banana and egg.Briefly explain why chicken fat, which largely consists of various triacylglycerols, has such a higher energy content per mole compared to sucrose.
- Assessing a remedy for flatulence Certain foods, particularly beans and legumes, contain substances that are indigestible by the human stomach, but which are readily metabolized by intestinal microorganisms producing flatulence. One of the components of such foods is stachyose. Beano is a commercial product that can prevent flatulence. Describe the likely breakdown of stachyose in the human stomach and intestines and how Beano could contribute to this process. What is the appropriate name of the active ingredient in Beano responsible for preventing flatulence?Calculate the ATP yield from full oxidation of the fatty acids from a triglyceride with 3, 22 carbon fatty acid moleculesdescribe the IR spectra pattern of ascorbic acid (Vitamin C)
