- Describe the effects of a diet that includes large amounts of fructose.During extended fasting (≥ 4 days), what is/are the purpose(s) of tissue protein breakdown? Circle ALL that apply. a. Dispose of excess nitrogen groups so ammonia doesn't accumulate b. Provide precursors to the Liver, Kidney, Sm. Intestine for gluconeogenesis c. Provide precursors to the liver for ketogenesis d. Provide energy to the skeletal muscles through Amino Acid oxidation e. Provide energy to the liver through Amino Acid oxidationB. What stage does the reaction occur? CHOICES: (Stage 1: Digestionand Hydrolysis) , ( Stage 2: Degradationand Oxidation) , (Stage 3: Energy Generation) Conversion of amino acid to keto acid Aspartate to fumarate Valine to succinyl CoA Activity on peptide bond cleavage Protein to large polypeptides Activation of zymogens Pyruvate to oxaloacetate Interchange of amino group Participation of coenzyme linked to Vit. B6 Production of glutamate
- Bypass I of gluconeogenesis requires a source of energy. This energy comes from: a oxidation of the metabolite b 6 ATP c 2 ATP d 1 ATP + 1 NADHDefine the following terms:a. b-oxidationb. carnitinec. ketogenesisd. ketone bodiese. ketosisHelp fill in the blanks Extended fasting will activate the processes of [glycolysis/gluconeogenesis] and [fatty acid synthesis/b-oxidation]. These processes will work to deplete [oxaloacetate/acetyl-CoA] and increase [oxaloacetate/acetyl-CoA]. As a result, flux through the citric acid cycle will [increase/decrease]. Ketone bodies will be produced in this state allowing for [NAD+/CoA/glucose] to be recycled. Ketosis also occurs in people on a [carb-rich/carb-poor] diet for similar reasons. Bafflingly at first, hyperglycemia in diabetics may also cause ketosis. The problem is not in the bloodstream in these patients, but in the hormones. Without insulin, [GLUT1/ GLUT2/GLUT4] will not appear on muscle cell membranes to clear glucose, and liver cells continue to receive signals from glucagon. Glucagon will [activate/inhibit] pathways that catabolize carbohydrate and [activate/inhibit] pathways that catabolize fatty acids to preserve the carbohydrate fuel of choice for the…
