Photosynthesis and Cellular Respiration at the Atomic Level
How can we demonstrate the law of conservation of matter is true using molecular models?Copyright 2017 Tuyen C. Duddles, Michigan State University RET
Students learn about the basic principles of electromicrobiology—the study of microorganisms’ electrical properties—and the potential that these microorganisms may have as a next-generation source of sustainable energy. They are introduced to one such promising source: microbial fuel cells (MFCs). Using the metabolisms of microbes to generate electrical current, MFCs can harvest bioelectricity, or energy, from the processes of photosynthesis and cellular respiration. Students learn about the basics of MFCs and how they function as well as the chemical processes of photosynthesis and cellular respiration
To design microbial fuel cells (MFCs), engineers must understand the chemical mechanisms of photosynthesis and cellular respiration that occur within organisms like yeasts, algae or bacteria. Engineers must also understand electron transport pathways—a complex series of interactions between electrons—that play a key role in generating photosynthesis and cellular respiration processes; particularly if they wish to harvest electrons for electrical power generation.
After this lesson, students should be able to:
- Describe the processes of photosynthesis and cellular respiration.
- Explain the relationship between cellular respiration and photosynthesis and their connection to the cycling of matter and energy.
- Explain how engineers apply scientific knowledge to make technology that can solve societal problems.
