Aspirin inhibits the cyclooxygenase pathway and blocks the synthesis of certain factors. Name these factors.

This is a depiction of the connection between the urea cycle, the malate-aspartate shuttle, and the citric acid cycle. In this depiction, blank boxes with numbers are hiding the name of a metabolite. Using the list below the pathway name the missing metabolites. Hint: Start by identifying #1, #6, and #7 and work from there.

Glutamine synthase has how many subunits? A、8 B、10 C、6 D、12

Infants do not have the ability to metabolize ethanol and are assumed to lack the enzyme alcohol dehydrogenase? What kind of regulation is this?

Part B

Enolase has a glutamic acid residue in its active site. Describe the experiment that was done that provided evidence for the proposed function of the glutamic acid residue in catalysis by enolase.

Corticosteroids (a type of hormone), and Nonsteroidal Anti-inflammatory Drugs (NSAIDs) are non-narcotic pain relievers. Both medications are prescribed to reduce inflammation in the body.  NSAIDs such as aspirin, acetaminophen, and ibuprofen are able to reduce pain, fever, and inflammation by blocking the action of the cyclooxygenase enzyme (COX) that catalyzes the conversion of arachidonic acid into prostaglandins. Common corticosteroids include prednisone, cortisone, and methylprednisolone.  Choose one of these three corticosteroids.  Do some internet research on the corticosteroid that you choose and then explain how the drug works to reduce inflammation.

Write the sequence of steps for the biosynthesis of phosphatidylcholine by the salvage pathway from oleate, palmitate, dihydroxyacetone phosphate, and choline. Name the enzyme for each step.

Why most of the clinical features of the diseases Krebs Cycle inborn errors ( a- ketoglutarate dehydrogenase deficiency, succinate dehydrogenase deficiency, and fumarase deficiency) involve muscle and nerve tissue?

Alcohol dehydrogenase catalyzes the oxidation of an alcohol to the next highest state of oxidation, an aldehyde. How does this partially explain the toxicity of methanol?
