PORTAGE LEARNING CHEM 210 - MODULE 8 PROBLEM SET. This study source was downloaded by from CourseH on 02-14-2022 16:13:24 GMT -06:00 What is the “unifying” theory covered in this module? Chemiosmotic theory How many ATP are produced per NADH molecule? Per FADH2 molecule? NADH produced 2.5 ATP, while produces FADH21.5 ATP. In the figure below, several portions of a molecule have dashed circles. Which portion of the molecule, A, B, C, or D, would be removed in oxidative deamination? Briefly explain. Part D. This is the amine portion of the amino acid.

The carbon skeleton becomes acetyl-CoA, then ATP. Why is urea such a good molecule for excreting nitrogen from cells? It has a high density of nitrogen in a small molecule, and it can form numerous hydrogen bonds with water. Given the urea cycle below: This study source was downloaded by from CourseH on 02-14-2022 16:13:24 GMT -06:00 A. In the overall processing of NH4+, how many molecules of ATP are invested? B. What molecule from the urea cycle can enter the citric acid cycle? C. What is Pi? D. Which two amino acids were studied in Module 3? A. 3 ATP molecules, overall. 2 ATP from Reaction-A and 1 in Reaction-2. B. Fumarate C. Inorganic phosphate or inorganic orthophosphate. D. Aspartate and arginine were studied in Module 3. Question 7 This study source was downloaded by from CourseH on 02-14-2022 16:13:24 GMT -06:00 0 / 0 pts What is an integral protein? A protein firmly embedded in the lipid bilayer Question 8 How many complexes are in the ETC? Four complexes named complex I, II, III, and IV Question 9 0 / 0 pts At which ETC complex is H2O produced? How is it produced? At complex IV by the following reaction: O2 + 4e- + 4H+ → 2H2O Question 10 0 / 0 pts What complex oxidizes NADH? How about FADH2? Complex I for NADH. Complex II for FADH2. Question 11 0 / 0 pts This study source was downloaded by from CourseH on 02-14-2022 16:13:24 GMT -06:00 At which complex is water produced from oxygen? Complex IV Question 12 0 / 0 pts How is the H+ gradient formed? Complexes I, III, and IV pump these ions from the matrix to the intermembrane space. Question 13 0 / 0 pts What is the purpose of FO and F1 in ATP synthase? FO contains the pore through which H+ ions flow causing its rotation. The rotation of FO causes F1 to catalyze the formation of ATP from ADP and Pi. This study source was downloaded by from CourseH on 02-14-2022 16:13:24 GMT -06:00
