The original source of energy for all living things on earth is the sun. This energy is converted into a usable form for living things through the process of photosynthesis, in which plants and some other organisms absorb sunlight, carbon dioxide, and water to produce glucose (sugar) and oxygen. Living things then utilize this glucose as a source of energy through cellular respiration.
The main source of energy for all living things is carbohydrates. They are broken down into glucose during digestion and then used in cellular respiration to produce ATP, which is the primary energy carrier in cells.
Living things use enzymes instead of a heat source of activation energy because they speed up chemical reactions as well as the metabolism in those living things.
