Photosynthesis & Cell Respiration
By Emily and Anna
When an animal, such as this golden retriever eats anything and digests its food it is broken down into smaller units until it becomes small enough to be used in our cells as glucose molecules. At the very same time the animal is breathing in oxygen that travels from the lungs through the bloodstream into small blood vessels until it reaches our cells. When the glucose and oxygen reaches our cells, we perform cellular respiration. This process starts in the cells’ cytoplasm and is completed in the mitochondria, In those tiny organelles, one molecule of glucose with 6 molecules of oxygen are changed into 36 molecules of ATP and the energy cells can use to get things done.
C6H12O6 (1 glucose molecule) + 6 O2 6 CO2 + 6 H2O + 36 ATP (ENERGY) carbohydrate + oxygen carbon dioxide + water + ATP energy
