September 27, 2007 Chapter 8 Glycolysis and Cell Respiration Glucose Glucose is a key energy-storing molecule: o Nearly all cells metabolize glucose for energy o Glucose metabolism is fairly simple o Other organic molecules are converted to glucose for energy harvesting During glucose breaking down, all cells, release the solar energy that was originally captured by plants through photosynthesis, and use it to make ATP Overall equation o C2H12O6 + 6O2 6CO2 + 6H2O + ATP Overview of glucose break down
