This lesson primarily addresses goals in biology, however, it provides helpful reinforcement of concepts in civics and economics as well. It is designed to help students understand how ATP (adenosine tri-phosphate) can be considered the currency of cells. ATP must be “spent” in order for all metabolic processes to continue. Furthermore, during ATP production, ATP must be “invested” before more ATP can be generated. With this concept in mind, students will use simple financial tables to explore the concepts of cost, revenue, and return on an investment as it applies to ATP in aerobic and anaerobic respiration.
