b. there is no deficit of the initial substrate to begin glycolysis.
c. the respiratory processes in your brain cells are moving atomsfrom glycolysis through the citric acid cycle to the electrontransfer system.
d. after a couple of hours, you change position and stretch torest certain muscle cells, which removes lactate from thesemuscles.
e. after 2 hours, your brain cells are oxygen-deficient.
