Amino acid catabolism in skeletal muscle: the Alanine cycle Transamination reactions: the relationship between alanine/pyruvate; aspartate/oxaloacetate and glutamate/a ketoglutarate. Draw these transamination reactions with structures. GPCR and RTK signaling pathways. Use your knowledge of these pathways to predict how experimental situations will influence cell signaling as discussed in class. Products of amino acids and their role in signaling. Role of hormones in regulation of metabolism.

1. Select the TRUE statement about the citric acid cycle. A. Isocitrate dehydrogenase is a multienzyme complex that is very similar to the pyruvate dehydrogenase complex B. The two decarboxylation steps occur right after each other, first via oxidative alpha- decarboxylation, then via oxidative beta- decarboxylation. C. In one turn of the cycle, the two carbons that enter the cycle as acetyl CoA are the same two carbons that are released as CO2. D. A flavin containing dehydrogenase enzymes oxidizes...

Description: In order to go from glycolysis to the citric acid cycle we first must harvest pyruvates into acetyl CoA’s. This process involves many small steps which result in the main entrance in the citric acid cycle Instructions: For this presentation, your goal is to walk the audience through every step that is involved in generating acetyl CoA from Pyruvate. Be sure to focus on any cofactors need and show how this process is reset at the end to allow...
