Unformatted text preview: Photosynthesis is the process by which autotrophs make their own food. They use the energy from light to drive the oxidation of water and the fixation of carbon, ultimately producing sugars which they can use, store for later, or convert into building materials . Aerobic respiration is the process by which glucose and other carbon molecules are oxidized to create ATP, which cells use for energy. Chemistry determines the structure of all living things. For example, the Calvin reactions in autotrophs require the presence of carbon dioxide . However, if the leaf were completely porous it would lose too much water to transpiration. Thus, guard cells and stoma regulate the gas exchange, maximizing CO2 intake and minimizing water loss. 1.
