Study Notes
Greenhouse Effect
- Carbon Dioxide (CO2) is the primary gas responsible for the greenhouse effect.
Enzymes & Biological Processes
- Enzymes are biological catalysts that speed up chemical reactions in living organisms.
Atomic Structure
- Protons and neutrons, collectively called nucleons, are found in the nucleus of an atom.
Photosynthesis
- Carbon dioxide fixation is a characteristic of photosynthesis, where carbon dioxide is converted into organic compounds.
Law of Conservation of Mass
- The Law of Conservation of Mass states that in a chemical reaction, the total mass of the reactants before the reaction must equal the total mass of the products after the reaction.
