Question
Chapter 6, Problem 3.3SC
Summary Introduction
To describe: The functions of NAD (NADH) and FAD (FADH).
Introduction: The electron transport chain (ETC) involves a series of carrier molecules that are built in the inner membrane of the mitochondria. This inner membrane forms many folds termed as cristae. This chain occurs only in the presence of oxygen. The ETC yields 34 ATPs per molecule of glucose.

- Which of the following statements about the pentose phosphate pathway (PPP) is true? (A) The purpose of the pentose phosphate pathway is to produce NADH for use in anabolic pathways and ribose 6-phosphate for nucleotide synthesis.(B) The oxidative arm of the PPP produces (2) NADPH per glucose 6-phosphate that enters the pathway. (C) Phosphopentose isomerase converts the ribose 5-phosphate made in the oxidative arm of the PPP into ribulose 5-phosphate that is used to form the ribose sugar of nucleotides.(D) The non-oxidative arm of the PPP interconverts between ribose 5-phosphate and a variety of intermediates of b-oxidation. (E) One of the functions of the PPP is to provide NADPH that inhibits glutathione reductase so that it cannot oxidatively damage RBCs.arrow_forwardThe function of NAD+ and FADH+ is: A)To make sugar from carbon Dioxide B)To pump hydrogen ions across a membrane C)To capture and hold high energy electrons D)To turn the rotor of ATP Synthase E)To take low energy electrons from the electron transport chainarrow_forwardWhy are electron carriers (NAD+/NADH and FAD/FADH2) so important in the process of cellular respiration? A)NADH and FADH2 are major components of the ETC, so without them, there would be no ETC in the cell. B)They deliver electrons to the ETC, which in turn sets up chemiosmosis, where most of the ATP is generated. C)They separate the electrons from the protons so that the protons can be moved out of the mitochondrion. D)The electrons that they carry are able to directly phosphorylate ADP in order to generate the bulk of ATP in the cell. E) They transport protons across the mitochondrial membrane. 14.arrow_forward
