WebMar 20, 2024 · The chemical reactions that take place in living cells are similar as well. Green plants use the energy of sunlight to convert water (H 2 O) and carbon dioxide (CO 2) to carbohydrates (sugars and starches), other organic ( carbon -containing) compounds, and molecular oxygen (O 2 ). WebChemically, combustion is no more than the reaction of a fuel (wood, oil, gasoline, etc.) with oxygen. For combustion to take place there must be a fuel and oxygen gas. robert plant feather symbol meaningWebA substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called enzymes.
