What is Living Things are made of?
Cells are made of molecules. All living things contain four major carbon-based molecules:
- Carbohydrates: Carbohydrates are used inside cells mainly for quick energy, but also can be used in structure and cell signaling.
- Proteins: Proteins are the building blocks of cells and carry out many important functions from transport to catalyzing chemical reactions to structure.
- Lipids: Lipids are used for long-term energy storage.
- Nucleic acids: Nucleic acids contain the genetic information of the cell and include molecules like DNA and RNA. In addition to these four molecules, cells are also made of inorganic ions such as sodium or potassium and water.
