Chapter 6.2, Problem 1CSC
Energy Unleashed
Marathoners rely on glycogen stored in their muscles and liver for much of the energy to power their run. Glycogen consists of long, branched chains of glucose molecules. When energy is needed, glucose molecules are cleaved from the chain and then broken down into carbon dioxide and water. This exergonic reaction generates the chemical energy in ATP that will power muscle contraction. The carbon dioxide is exhaled as the runners breathe rapidly to supply their muscles with adequate oxygen. The water generated by glucose breakdown (and a lot more that that runners drink during the race) is lost as cooing sweat.
The glucose molecules In muscle and other cells do not need to be ignited and do not literally bum as they are broken down, so how do cells provide activation energy and control the release of chemical energy to allow it to do work?

The average cell at rest hydrolyzes 10,000,000 ATP molecules per second.You are studying the stem cell population found in intestinal Crypts.In the intestine there are s total 5*1011 cell.The stem cells have a 85% higher metabolism than an average resting cell.ATP hydrlysis yield 7.4 kCal/Mole ATP(Avogadro's number is 6.023*1023)
How many Kcal of energy are used per day by this population of cells?
Assuming 32 ATP per glucose oxidative metabolically how many moles of glucose are consumed per day?

- EVOLUTION LINK The reactions of glycolysis are identical in all organismsprokaryotes, protists, fungi, plants, and animalsthat obtain energy from glucose catabolism. What does this universality suggest about the evolution of glycolysis?arrow_forwardIn the 1950s, a diet pill that had the effect of poisoning ATP synthase was tried. The person taking it could not use glucose and lost weightand ultimately his or her life. Today, we know that the immediate effect of poisoning ATP synthase is: a. ATP would not be made in the electron transfer system. b. H+ movement across the inner mitochondrial membranewould increase. c. more than 32 ATP could be produced from a molecule ofglucose. d. ADP would be united with phosphate more readily in themitochondria. e. ATP would react with oxygen.arrow_forward3arrow_forward
