Question
Chapter 8.2, Problem 4C
Summary Introduction
To determine: The rate of oxidative phosphorylation if most of the adenosine diphosphate (ADP) in the cell were to become converted to adenosine triphosphate (ATP).
Concept introduction: The process, in which ATP is formed due to the transfer of electrons from nicotinamide adenine dinucleotide (NADH) and flavin adenine dinucleotide (FADH2) to oxygen (O2) by a series of electron carries, is called as oxidative phosphorylation. This process occurs within the mitochondria.

Consider ten glucose molecules that enter a cell. How many ATP can be generated by the complete catabolism of these into CO2 and H2O? If all ten are first incorporated into glycogen, liberated from glycogen, and then fully catabolized into CO2 and H2O, does the ATP tally increase, decrease or stay the same? Consider that 1 UTP = 1 ATP. Explain. Describe the processes which produce ATP and provide a balanced equation of glucose, CO2, H2O and O2
Calculate the amount of ATP’s that will be formed during the oxidative phosphorylation process if: 46 NADH + H and 12 FADH + H is available .
Arrange the sequence of events in Oxidative Phosphorylation. (1-5)
As the H+ ions move through the ATP synthase it'll provide the power to make the ATP synthase to
turn. As it turns, a phosphate group is added to an ADP, forming a proton gradient-energy as ATP.
With the help of a channel protein called ATP synthase, these H* ions are transferred back to the
matrix.
The electrons are passed to another electron carrier called cytochrome C (cyt C), which carries the
= electrons to enzyme complex IV. Here, the last batch of H* ions are pumped into the intermembrane
space.
Enzyme complexes I and Il then transport the electrons through ubiquinone (Q), a mobile electron
carrier. Q is reduced to QH, in the process and delivers the electrons to enzyme complex III. As this
happens, more H* ions are pumped into the intermembrane space.
The NADH and FADH2 produced from the previous stages of cellular respiration bring electrons
across the transport chain to initiate the oxidative phosphorylation.
