Question | Answer |
carbohydrate | A molecule in living things made of carbon, hydrogen, and oxygen. Sugars and starches are examples. They are used for energy or to build things. |
chemical reaction | The way that chemical change takes place. It does this by changing the position of its atoms. Chemical bonds are broken or formed. |
lipid | A carbon-based molecule in living things. Lipids are fats, oils, and waxes used for energy or to build things. They are made from subunits of fatty acids. |
nucleic acid | Carbon-based molecules that carry the genetic code of a living thing. Examples are RNA and DNA. DNA has the code to make proteins. RNA translates the code into proteins. |
protein | A large molecule in living things. It is made up of chains of amino acids. They control the chemical activity of a cell. They support growth and repair. |
cellular respiration | How cells free up the energy in sugars. Cells need oxygen to do this. |
chemical energy | The energy freed up by a chemical reaction. Examples are burning wood or gas to make heat. |
chlorophyll | The matter that makes the green color in leaves of plants. It takes in the energy in light and changes it to chemical energy. It is also found in some algae and bacteria. |
fermentation | A chemical process in which cells break down sugar and give off energy when no oxygen is there. |
glucose | A sugar molecule. It is a major source of energy for cells. It is made by photosynthesis. |
photosynthesis | The way green plants and other producers absorb light and use it to change carbon dioxide and water into glucose and oxygen. Glucose is a sugar. It is energy rich. |
