Below is a list of steps that occur after an exercising muscle cell begins degrading amino acids for ATP production. For each step, choose (A) if the process occurs in the muscle cell and (B) if the process occurs in the liver.
It will be easiest to answer this question if you first put the steps in order, then decide in which organ they occur.
______ Alanine is transaminated with a-ketoglutarate.
______ Branched chain amino acids are transaminated with a-ketoglutarate.
______ Glutamate is deaminated.
______ Glutamate is transaminated with pyruvate.
______ Ketoacid skeletons resulting from branch chain amino acids enter the CAC.
______ Pyruvate enters gluconeogenesis.
______ Urea is formed from the nitrogen removed from the original branched chain amino acid.

- If someone is starving, how does a combination of anabolic and catabolic processes keep them alive? Explain in detail. Please include an explanation with metabolism AND take into account we are discussing starvation (or fasting ) conditions.arrow_forwardA patient complains of painful muscle cramps when performing strenuous physical exercise. A muscle biopsy indicates a higher than normal concentration of muscle glycogen. a. Which enzyme of glycogen metabolism is affected? b. Discuss how the defect of this enzyme affects glycogen metabolism.arrow_forwardPlease answer this question with the simplest answer and no more than five sentencesarrow_forward
- When transaminated, the three branched-chain amino acids (valine, leucine, and isoleucine) form compounds that have the characteristic odor of maple syrup. An enzyme known as branched-chain a-keto acid dehydrogenase converts these compounds into CoA esters. People who do not have this enzyme have the genetic disease known as maple syrup urine disease, so called because their urine smells like maple syrup. a. Draw the compounds that smell like maple syrup.b. Draw the CoA esters.c. Branched-chain a-keto acid dehydrogenase has five coenzymes. Identify them.d. Suggest a way to treat maple syrup urine disease.arrow_forwardI don't get it at all. I struggled with my homework. Can you help me? Can you help me to explain to me to get the difference between ketogenesis and ketoacidosis., please?arrow_forward_______________ amino acids are degraded to pyruvic acidand citric acid cycle intermediatesarrow_forward
- Describe why lactic acid is produced during a prolonged strenuous activity and how lactic acid affects the muscle(s) that are being exposed to lactic acid. Lastly, in your response please indicate where lactic acid goes to be safely decomposed and stored. In your response, you should mention fatigue, anaerobic respiration, and the liver.arrow_forwardChoose the best answers for each missing word from the list below. ____ regulated by ATP, Aspartate transcarbamoylase (ATCase) is (1) which is a (2)________________ regulator, and by CTP which binds to the (3)____ subunit of ATCase and shifts the conformational equilibrium to the (4). T state. CTP regulation of ATCase is called (5)________ 1) allosterically, 2) positive, 3) regulatory, 4) inactive, 5) feedback inhibition 1) covalently 2) positive, 3) regulatory, 4) active, 5) feedback inhibition 1) allosterically, 2) negative, 3) regulatory, 4) inactive, 5) feedforward activation 1) allosterically, 2) negative, 3) catalytic, 4) active, 5) feedforward inhibition 1) irreversibly, 2) positive, 3) catalytic, 4) inactive, 5) feedback inhihitionarrow_forwardHexokinase deficiency (HKD) is a congenital disease that can disrupt intracellular glucose levels. Please provide an explanation of the diseases impact on intracellular glucose levels and the mechanism by which how GLUT1 regulates this disrupted glucose level.arrow_forward
- The heart cannot convert lactate back to glucose, as the liver does, but instead uses it as a fuel. What is the ATP yield from the complete catabolism of one mole of lactate?arrow_forwardAn enzyme with high activity in an acidic environment would be _____________________ pepsin amylase gatrin sucrase trypsinarrow_forward
