Amino Acids, Proteins and Porphyrins
Which of the following statement is not true about flavoproteins:
|A||Combine with Fe and Mo to form metal flavoproteins|
|B||These are active form of riboflavin|
|C||Carotenoid is the prosthetic group in flavoproteins|
|D||Cellular oxidation reduction protein|
a. Flavoprotein are involved in cellular oxidation-reduction reactions.
b. Flavoproteins are active form of riboflavin and combine with Fe and Mo to form metalolflavoproteins.
c. Flavin Mononucleotide (FMN) or Flavin Adenine Dinucleotide (FAD), and not carotenoids, act as prosthetic groups of flavoprotein enzymes.
d. Reactions involving flavoprotein enzymes are (frequently asked in MCQs):
i. Amino acid deamination.
ii. Purine degradation.
iii. Fatty acid oxidation
iv. Oxidative decarboxylation of pyruvate
v. Conversion of succinate to fumarate in citric acid cycle
e. Degradation of aldehydes
