Exploring the Energy Cycle: Photosynthesis and Cellular Respiration

The video explores the processes of photosynthesis and cellular respiration, highlighting how plants and animals utilize these processes to produce energy. Photosynthesis occurs in plant chloroplasts, converting carbon dioxide and water into glucose and oxygen using sunlight. Cellular respiration takes place in mitochondria, where glucose and oxygen are transformed into ATP, carbon dioxide, and water. The video emphasizes the cyclical nature of these processes and their importance in sustaining life. It concludes with a call to action for viewers to engage with more I-STEM content.
