PORTAGE LEARNING CHEM 210 - MODULE 8 EXAM. Portage Learning Chem 210 - Module 8 exam. True or False: The majority of reactions of the urea cycle occur in the cytosol. TRUE True or False: NADH yields 1.5 ATP molecules after donating electrons and hydrogenatoms to the electron transfer chain (ETC). FALSE True or False: GTP is invested in the urea cycle. FALSE True or False: There are six complexes associated with the ETC. FALSE True or False: In the production of ATP via ATP synthase, the H+ ions move from the mitochondrial matrix to the intermembrane space. FALSE The urea cycle involves reactions (only those in the cyclic portion of the process). 1 2 Question 1 3 / 3 pts Question 2 3 / 3 pts Question 3 3 / 3 pts Question 4 3 / 3 pts Question 5 3 / 3 pts Question 6 3 / 3 pts Question 9 3 / 3 pts 3 4 5 4 Which amino acids are involved in the urea cycle?
