| Question | Answer |
|---|---|
| ATP (adenosine triphosphate) | molecule used by cells to deliver energy for chemical reaction |
| Carbohydrate | a compound of carbon, hydrogen, and oxygen in the ratio of 1-2-1. It is a source of energy |
| Catalyst | a material that speeds up a chemical reaction without being used itself |
| Chemical bond | attractive force that holds two atoms together in a molecule |
| Covalent bonds | chemical bonds formed by the sharing of electrons between two atoms |
| Dehydration | the process by which water is removed from any substance |
| DNA (deoxyribonucleic acid) | a complex, double stranded nucleic acid molecule that is found in most living things that acts as the primary genetic material. |
| DNA (deoxyribonucleic acid) | It controls structure of proteins and influences chemical reactions within the body, double stranded nucleic acid that acts as a primary genetic material |
| Element | matter that is only made of one kind of atom |
| Enzyme | a protein that acts as a catalyst for a biochemical reaction |
| Hemoglobin | an iron-containing molecule in red blood cells that gives blood its color and carries oxygen and carbon dioxide |
| High energy bonds | a chemical bond containing several times more stored energy that is usual |
| Hormone | a chemical signal, secreted by specialized glands, that travels through the bloodstream and regulates the body’s activities |
| Hydrolysis | a chemical reaction in which large molecules are broken down by the addition of water |
| Lipid | a class of organic molecules that includes fats and waxes that organisms may use to store energy |
| Molecular energy | the amounts of energy found within the chemical bonds that hold together a molecule |
