Question

12. (2 extra credit pts Take a close look at the reactions where FAD is involved and is transformed to FADH2. What type of reaction is typically associated with FAD? You find examples in gycolysis, P- oxidation and citric acid cycle to help vou decide, Use the same type of labels as for question 8. 13. (4 pts) Use the information from auestion 12 to help you predict the reactant of the following reaction. OH FADH FAD 14. (4 pts) The 4th step of the Krebs cycle occurs in multiple steps. Predict the product resulting from the second step. COo Oa C C H-C-H H-C-H +H Decarboxylation NADH+H NAD C-H H- H-C-H ČOo COo Predict this product CoA-SH H,O SCOA O -C -C-H H- H -C-H COO 15. (3 pts) What is the name of the bond that is the newly formed linkage (see arrow) in step 3 in the reaction scheme shown in question 14.

Answer 1

12) FAD accept to electrons and two protons to give FADH2 thus it is involved in the oxidation reaction where reactant get Oxidized.
