Step 1
Photosynthesis
Answer
Photosynthesis is a process that occurs in plants, primarily in the chloroplasts, where light energy is converted into chemical energy. It requires chlorophyll and uses light, carbon dioxide (CO₂), and water (H₂O) as inputs. The products of photosynthesis are glucose and oxygen (O₂). This process is considered anabolic because it synthesizes complex molecules from simpler ones.
Step 2
Respiration
Answer
Respiration, on the other hand, does not require chlorophyll and does not utilize light. Instead, it primarily uses glucose as a substrate and produces energy. The byproducts of respiration are carbon dioxide (CO₂) and water (H₂O). This process occurs in the mitochondria and is classified as catabolic, as it breaks down complex molecules to release energy.
