We have discussed the aerobic metabolism of glucose extensively in this class. To capture and use the energy in glucose to make ATP, we must utilize 4 different sequential pathways/steps. Starting with one glucose molecule and eventually ending with CO, H;O and ATP, list the 4 pathways/steps in order and tell me what molecules enter each pathway, and what the final products of each pathway are.

Lys His ATP NH ; afafafor OH OH qat Glu Tyr Asp a. What is the most likely chemical interaction occurring between the tyrosine and the ribose of ATP? b. List one mutation to the lysine (Lys) in the binding site that would likely result in the kinase NOT being able to bind ATP (state the change in amino acid, not in the DNA or mRNA). In one sentence, explain why this mutation would likely lead to this change. Be as specific as possible.

Why does growth of ETPUM in Medium # require oxygen? ' ink about this in terms of howETPUM can generate a net gain in ATP by processing polyurethane. Remember that the degradationof polyurethane by polyurethanase does not expend ATP. In order to answer this question, address eachof the following questions in your answer:a. Is there a net gain or loss of ATP during the transport of the citrate?b. Consider the ATPs that can be generated via substrate-level phosphorylation. Will glycolysis beuseful for generating any ATPs during growth on polyurethane? How many ATPs can be generatedvia TCA? Is this enough to support growth (is there a net positive in the ATP tally)?c. Now consider how else ETPUM can generate ATPs (if not by substrate- level phosphorylation). Canthis process generate a net positive in the ATP tally?d. Now explain the importance of oxygen as relates to the ATP tally.
is this stement false? Intracellular concentrations in resting muscle are as follows: Fructose-6-phosphate (1.0 mM)Fructose-(1-6)-bisphosphate (10.0 mM)AMP (0.1 mM)ADP (0.5 mM)ATP (5.0 mM)Pi (10.0 mM)Under the above conditions the Phosphofructokinase reaction in muscle is more exergonic than under standard conditions.
