Which statement is true about photosynthesis and cellular respiration?

Answer: Photosynthesis and cellular respiration are complementary processes that sustain life on Earth. Here’s how they relate:

  1. Energy Conversion:

    • Photosynthesis converts light energy into chemical energy stored in glucose. This process occurs in plants, algae, and some bacteria.
    • Cellular Respiration converts the chemical energy in glucose into ATP (adenosine triphosphate), which cells use for energy. This process occurs in nearly all living organisms.

  2. Gas Exchange:

    • Photosynthesis takes in carbon dioxide (CO₂) and releases oxygen (O₂) as a by-product.
    • Cellular Respiration consumes oxygen (O₂) and releases carbon dioxide (CO₂) as a by-product.

  3. Location:

    • Photosynthesis occurs in the chloroplasts of plant cells.
    • Cellular Respiration occurs in the mitochondria of both plant and animal cells.

  4. Equation:

    • Photosynthesis:

      6CO_2 + 6H_2O + light \ energy \rightarrow C_6H_{12}O_6 + 6O_2

    • Cellular Respiration:

      C_6H_{12}O_6 + 6O_2 \rightarrow 6CO_2 + 6H_2O + ATP

Summary: Photosynthesis and cellular respiration are interconnected processes. Photosynthesis generates glucose and oxygen, which are then used in cellular respiration to produce energy (ATP), releasing carbon dioxide and water as by-products.
