Textbook Question
Chapter 9, Problem 10TYPSS
QUANTITATIVE Early estimates suggested that the oxidation of glucose via aerobic respiration would produce 38 ATP. Based on what you know of the theoretical yields of ATP from each step, show how this total was determined. Why do biologists now think this amount of ATP/glucose is not achieved in cells?

Generate a table that compares the limits of ATP production of different metabolic mechanisms. Include information on how rapidly ATP production can be accelerated and how rapidly each mechanism can be reinitialized.
Trace the fate of hydrogens removed from glucose during glycolysis when oxygen is present in muscle cells; compare this to the fate of hydrogens removed from glucose when the amount of available oxygen is insufficient to support aerobic respiration.
How would the ATP yield per glucose molecule be different if enzyme specificity forced FADH2 to be used in place of NADH throughout aerobic metabolism?

Be sure to directly discuss inputs and outputs of BOTH processes. Include all phosphorylated compounds and high-energy electron carriers, and briefly EXPLAIN HOW these are produced at each stage of respiration. WHERE does each stage happen? Explain HOW energy from high energy electron carriers is converted to ATP during respiration in mitochondria or aerobic bacteria.arrow_forwardFor many years, the total number of molecules of ATP produced for each molecule of glucose in aerobic respiration was given as 38. Later, it was estimated to be closer to 36, and now it is believed tobe closer to 30. What factors must be considered in estimating the yield of ATP molecules? Why are the recent numbers considered to be approximate values?arrow_forward
