Prosthetic groups - Study guides, Class notes & Summaries

Intro to Enzymes correct answers - a requirement for life is the ability to efficiently and selectively catalyze chemical reactions - most biomolecules are very stable and the uncatalyzed transformations would be too slow to permit life - experiments done showed that dead yeast could still convert sugars into alcohol indicated that the reactions of life could be separated from life - there was a factor in yeast catalyzing the reaction vitalism correct answers a belief that originally, bioc...

Which of the following proteins is likely to have quaternary structure? - A multimeric protein that contains multiple peptide chains Prosthetic groups are complex nonprotein molecules that participate in catalysis by providing functional groups that form a covalent intermediate between the enzyme and the substrate. Which of the following is an example of a coenzyme or cofactor that participates in a covalent catalysis reaction? - Pyridoxal phosphate

Changes in the physiological variables listed below can alter the affinity of hemoglobin for oxygen. Which of the following will lower the affinity of hemoglobin for oxygen? a) decrease in protons b) increase in 2,3 bisphosphoglycerate (BPG) c) increase in pH d) decrease in CO2 - Answer Increase in 2,3 bisphosphoglycerate (BPG) Domains are common structural elements that retain a particular function within the protein. Which of the following is an example of a protein domain? a) a prosth...

Which of the following is expected to appear in excess in the body of a patient with inherited homocystinuria? ANS Methionine - know the 20 common amino acids, in this disease the cysteine synthesis pathway is blocked so the answer is not C, which is cysteine. glycine and arginine are not mentioned in the passage, so they are incorrect. Both methionine and homocysteine would be found in excess and only methionine is an answer choice homocystinuria may present in cases of vitamin defic...

Allosteric activators of hemoglobin will increase substrate binding through which of the following mechanisms? Binding the protein and keeping it in the R conformation. Allosteric activators of hemoglobin stabilize the R state, allowing increased affinity for oxygen and rapid saturation. The R-group on valine does not have an active group to participate in covalent catalysis. Which amino acids most commonly participate in covalent catalysis cysteine, serine, and histidine Which o...
