PORTAGE LEARNING CHEM 210 FINAL EXAM LATEST UPDATED EXAMINATION STUDY GUIDE 2023 Question 26 5 / 5 pts Question 27 Not yet graded / 10 pts Complex I Complex II Complex III Complex IV ATP synthase ATP SYNTHASE The following processes result in either the “Production of ATP" or in the “Consumption of ATP”. Put each of the following into the appropriate category. 1. Fructose-6-phosphate forms Fructose-1,6-bisphosphate Consumption of ATP 2. Oxidative phosphorylation Production of ATP 3. Glucose forms two pyruvates Production of ATP 4. Pyruvate forms acetyl-CoA Production of ATP 5. NH4+ is made into urea Consumption of ATP In human cells, amino acids are degraded to ammonium NH4+ and carbon skeletons. How is the nitrogen then further processed and excreted from these cells? Nitrogen is processed separately from carbon and oxygen, in the urea cycle. The urea cycle is a four-step cyclic process that converts NH4+ to urea, which is then excreted from the body. Once the NH4+ is removed, it
