BIO 441A EXAM 3 STUDY GUIDE WITH COMPLETE SOLUTION. LECTURE ONE - METABOLISM INTRODUCTION ● Autotrophs synthesize all their own cellular constituents from simple molecules ● Heterotrophs obtain energy through oxidation of organic compounds and therefore rely on autotrophs ● Metabolism involves many reactions such as ○ Glycolysis/gluconeogenesis ○ The citric acid cycle ○ Oxidative phosphorylation ● Catabolism is the degradation of biomolecules ○ Energy rich nutrients are...

What neurotransmitter stimulates release of epinephrine from adrenal medulla? - Answer- acetylcholine What is a metabolite if epinephrine that suggests epi-secreting carcinoma? What is another assoc symptom? - Answer- metanephrine; assoc with HBP What does acetazolamide (carbonic anhydrase ib) treat? - Answer- glaucoma, epilepsy, altitude sickness, congestive heart failure can cause dehydration Sickle cell anemia is due to... - Answer- pt mutation of Glu -> val What is a major ne...

b-oxidation needs mitochondria, sends FA (aceyl-CoA) to mitochondria via carnitine - b-oxidation occurs and acetyl-CoA occurs - acetyl-CoA cannot convert to pyruvate so cannot engage in gluconeogenesis Correct Answer-so why cant acetyl-coa derived from beta oxidation be used to convert into glucose? beta-oxidation, then can enter TCA (acetyl-coa_ Correct Answer-how do FAs enter TCA cycle? glycolysis Correct Answer-how does glucose enter TCA? conversion to acetyl-CoA or converted into...

2,4-Dinitrophenol and oligomycin inhibit mitochondrial oxidative phosphorylation. 2,4-Dinitrophenol is an uncoupling agent; oligomycin blocks the ATP synthesis reaction itself. Therefore, 2,4-dinitrophenol will: A) allow electron transfer in the presence of oligomycin. B) allow oxidative phosphorylation in the presence of oligomycin. C) block electron transfer in the presence of oligomycin. D) diminish O2 consumption in the presence of oligomycin E) do none of the above. - Answer-A) allow...
