Which of the following enzymes is part of both the TCA cycle and ETC? Succinate dehydrogenase The majority of energy in ATP is stored within which of the following bonds below? 1 In the case of deficiency in phenylalanine hydroxlase which of the following amino acids will become essential Tyrosine HFI is a rare recessive disorder. Which of the following is not a consequence of this enzyme deficiency? They will have low blood sugar (hypoglycemia), especially after eating fruits, fructose, sucrose, jaundice, excessive sleepiness, convulsions, irritability When the pancreatic beta cells sense an increase in glucose, the release of insulin is facilitated through which of the following mechanisms? Increase in intracellular calcium During aerobic exercise, intracellular calcium increases and which of the following will occur? Isocitrate dehydrogenase and alpha-keto glutarate dehydrogenase are allosterically activated by increase in calcium Within the red blood cell, the lack of which of the following compounds can result in exercessive hemolysis and jaundice? NADPH After fasting for 6 hours which of the following would be consistent with hormone levels of this individual? Insulin (-), Glucagon (+), Cortisol (+), Epinephrine (+) There is a gain of function mutation in the insulin receptor substrate that makes it permanently bound to the insulin receptor substrate that makes it permanently bound to the insulin receptor. Which of the following may occur as a result of this mutation. Increase in protein kinase B activity Which of the following activators is correctly paired with the enzyme that activates it? Fructose-2,6-bisphosphate : phosphofructokinase 1 NOT: o Glucose-6-phosphate : hexokinase o ATP : alpha-ketogluterate dehydrogenase o ATP : pyruvate kinase o Citrate : citrate synthase Fructose 1,6 bisphosphate will enhance the activity of which of the following enzymes? Under fed conditions, glucose taken up by the liver is primarily used for which of the following processes? It is used as a substrate for liver glycogen synthesis In the malate aspartate shuttle, cytosolic oxaloacetate is __________ to form _________ as a means of moving reducing equivalents across the mitochondrial membrane. Which of the following process is considered to be catabolic? Glycogenolysis In an individual with a deficiency in PDC, which of the following reactions would be directly impaired? Pyruvate Acetyl CoA Monocytes are unique cells that secrete the cytokine, interleukin-1. Once released, this cytokine will bind a receptor on the outside of the monocytes and regulate its response. In this situation interleukin-1 is best described as which of the following? An autocrine signal NADH generated in the cytosol must be transported across the mitochondrial membrane in order to be oxidized by the electron transport chain. Which of the following shuttles or transporters can be used to facilitate the movement of cytosolic NADH into the mitochondria?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
