Threonine is converted to succinyl CoA through a process that produces 1 molecule of ammonia and 1 NADH while requiring 1 ATP. Consider that the resulting succinyl CoA can use a portion of the citric acid cycle to be converted to oxaloacetate. 1. (2 points) How many molecules of threonine would be required to produce one molecule of glucose? 2. (6 points) What is the net consumption or production of NADH, FADH2, and ATP for the synthesis of one molecule...
