This worksheet packet reviews the basics of Cellular Respiration and is an excellent introductory presentation for a high school program. The packet is divided into three sections: 1.) Cellular Respiration: An Overview, 2.) The Stages of Cellular Respiration, and 3.) Fermentation. Section 1, Cellular Respiration begins with the review over autotrophs/heterotrophs, calories, and aerobic respiration. Section 2, provides a detailed review of the specific stages of cellular respiration, including glycolysis, the citric acid cycle and the electron transport chain. Lastly, section 3, reviews the details of the lactic acid and alcohol fermentation. This packet corresponds to my Cellular Respiration PowerPoint that can also be found in my store.
