Question

1. Below is a depiction of the connection between the urea cycle, the malate-aspartate shuttle, and the citric acid cycle. In this depiction, blank boxes with numbers are hiding the name of a metabolite. Using the list below the pathway name the missing metabolites. Hint: Start by identifying #1 #6 and #7 and work from there. Questions #1-10 are each worth 0.5 point. 8 3. Cytosol 4 2. NADH Glutamate NAD+ a-Ketoglutarate Citrulline 7. Citrulline ?-Ketoglutarate Glutamate 1 Oxaloacetate NADH NAD Mitochondrial matrix Fumarate 1. Metabolite name: 2. Metabolite name (this metabolite breaks down into #3 and #8): 3. Metabolite name: 4. Metabolite name: 5. Metabolite name 6. Metabolite name (this is the same metabolite as #6): 7. Metabolite name (this same metabolite is moved to the cytosol can combine with citrulline to make #2 OR can be transaminated to make #9): 8. Metabolite name 9. Metabolite name: 10. Metabolite name
