Photosynthesis: Crash Course Biology #8
CrashCourse・2 minutes read
Photosynthesis is a complex process involving light-dependent and light-independent reactions, where sunlight is absorbed by chlorophyll in chloroplasts to produce glucose and oxygen. The Calvin Cycle uses ATP and NADPH to fix carbon dioxide onto RuBP, ultimately generating G3P for carbohydrate synthesis, highlighting the critical role of photosynthesis in sustaining life on Earth.
Insights
- Photosynthesis is a complex process involving light-dependent and light-independent reactions, where sunlight, carbon dioxide, and water are converted into glucose and oxygen.
- The Calvin Cycle, a crucial part of photosynthesis, uses ATP and NADPH to fix carbon dioxide onto RuBP, producing G3P for carbohydrate synthesis, illustrating the intricate steps involved in transforming sunlight, water, and carbon dioxide into essential components for life.

What is photosynthesis?
Photosynthesis is the process by which plants convert sunlight, carbon dioxide, and water into glucose and oxygen.
How do plants absorb water?
Plants absorb water through their roots and transport it to leaves via xylem tissues.
What is the role of chlorophyll in photosynthesis?
Chlorophyll in plant cells absorbs sunlight, initiating the process of photosynthesis.
What are the two types of reactions in photosynthesis?
Photosynthesis involves light-dependent and light-independent reactions to convert sunlight into glucose.
How is carbon dioxide involved in photosynthesis?
Carbon dioxide enters plant leaves through stomata and is used in the Calvin Cycle to produce glucose.
