During -oxidation of even-chain saturated fatty acids: Electrons are transferred to NAD+ Electrons are transferred to FAD Electrons are transferred to NADP+ Electrons are transferred from NADH Electrons are transferred from NADH Electrons are transferred from NADPH Acetyl CoA is formed as a product Acetyl CoA is used as a substrate ATP is used as an energy source Products can be used in the citrate cycle Products can be used in the electron transport system Products can be used for ketone body synthesis Products can be directly secreted into the blood stream. 2. During the synthesis of palmitate by fatty acid synthase: Electrons are transferred to NAD+ Electrons are transferred to FAD Electrons are transferred to NADP+ Electrons are transferred from NADH Electrons are transferred from NADH Electrons are transferred from NADPH Acetyl CoA is formed as a product Acetyl CoA is used as a substrate ATP is used as an energy source Products can be used in the citrate cycle Products can be used in the electron transport system Products can be used for ketone body synthesis Products can be directly secreted into the blood stream. 3. Ketogenesis Occurs when the concentration of acetyl CoA is high Occurs during starvation Occurs when one consumes a low glucose diet Occurs in uncontrolled diabetics Occurs in healthy individuals immediately after a meal Occurs in the liver Occurs in brain Occurs in the red blood cell 4. Which of the following pathways occur (in part or entirely) in the mitochondria: Glycolysis Gluconeogenesis Citrate cycle Electron transport/oxidative phosphorylation Photoelectron transport/photophosphorylation Calvin cycle Pentose phosphate pathway Cori cycle -oxidation of medium chain (eg. C16) fatty acids Ketone body synthesis Fatty acid synthesis Cholesterol synthesis Prosteglandin synthesis Urea cycle 5. Which of the following pathways take place (in part or entirely) in the cytoplasm? Glycolysis Gluconeogenesis Citrate cycle Electron transport/oxidative phosphorylation Photoelectron transport/photophosphorylation Calvin cycle Pentose phosphate pathway Cori cycle -oxidation of medium chain (eg. C16) fatty acids Ketone body synthesis Palmitate (C16) synthesis Cholesterol synthesis Prosteglandin synthesis Urea cycle 6. Which pathways would you expect to be active when acetyl CoA concentrations increase in the mammalian liver? Glycolysis Gluconeogenesis Citrate cycle Glyoxylate cycle Electron transport/oxidative phosphorylation Photoelectron transport/photophosphorylation Calvin cycle Photorespiration salvage pathway Pentose phosphate pathway Cori cycle -oxidation of medium chain (eg. C16) fatty acids Ketone body synthesis Fatty acid synthesis Cholesterol synthesis Prosteglandin synthesis Urea cycle 7. Which of the following pathways are stimulated by high energy charge: Glycolysis Gluconeogenesis Calvin cycle Pentose phosphate pathway (I gave credit for this as it is active in high or low energy charge but it is not stimulated) -oxidation of medium chain (eg. C16) fatty acids Ketone body synthesis Palmitate synthesis Cholesterol synthesis 8. Which of the following pathways are stimulated by NADP+: Glycolysis Gluconeogenesis Calvin cycle Pentose phosphate pathway Cori cycle -oxidation of medium chain (eg. C16) fatty acids Fatty acid synthesis Cholesterol synthesis Prosteglandin synthesis Urea cycle 9. Which of the following pathways are stimulated by insulin? Glycolysis Gluconeogenesis Glycogenolysis Glycogen synthesis -oxidation of medium chain (eg. C16) fatty acids Ketone body synthesis Palmitate synthesis Citrate Cycle 10. Which of the following molecules can be converted to glucose in humans? Glucogenic amino acids Ketogenic amino acids Lactate Palmitate Pyruvate ...
