II. Fill-In-the Blank:
1. Write the number of ATP molecules produced by each process listed below. Then add up these numbers to get the total number of
ATP molecules produced when one glucose molecule is broken down by cellular respiration.
______ ATP made in Glycolysis + ______ ATP made in Krebs cycle +______ ATP made in the Electron Transport Chain
=______ ATP total for the breakdown of one glucose molecule during cellular respiration
