Exploring Photosynthesis and Cellular Respiration Processes

The video tutorial covers photosynthesis and cellular respiration, starting with class announcements. It explains the photosynthesis process, including light-dependent reactions and the Calvin Cycle, highlighting the conversion of CO2 and water into glucose and oxygen. The tutorial then transitions to cellular respiration, detailing glycolysis, the Krebs Cycle, and the electron transport chain, emphasizing the conversion of glucose and oxygen into ATP, CO2, and water.
