| This type of chemical reaction will combine reactants to produce larger products. | Synthesis |
| This type of lipid is the body's long term energy storage molecule. | Triglyceride |
| This type of lipid is used by the body to create hormones. | Cholesterol |
| What are the major elements found in the body? | Carbon, hydrogen, oxygen and nitrogen |
| What determines the different elements found in nature? | The number of protons in the nucleus |
| What term is applied to cations and anions that form when an ionic compound is dissolved in water? | Both the cations and anions are called electrolytes |
| When the body demands energy, glycogen is broken down into: | Glucose |
| Which chemical bond results from the electrons of one atom being attracted to the protons of another atoms? | An ionic bond |
| Which is the function of ATP? | Transfers energy liberated from its breakdown for cell functions |
| List 3 carbohydrate? | Sugar, Glycogen, & Starches |
| List some facts about phospholipids? | The molecule is an important part of cell membranes, they contain a glycerol backbone, and the head group is polar |
