9th/10th Grade MYP Biology
| Term | Definition |
|---|---|
| Monomer | A small molecule that bonds together many times to form a large string like molecule (polymer) |
| Polymer | A large molecule made of many small monomers |
| Monosaccharide | One sugar molecule (ex. glucose or fructose). The main component of carbohydrates. |
| Disaccharide | Two sugar molecules bonded together (ex. glucose and fructose) |
| Polysaccharides | Many sugar molecules bonded together (ex. starch or glycogen. |
| Carbohydrates | A molecule made out of sugar (ex. monosaccharides, disaccharides, and polysaccharides) |
| Amino Acid | A molecule that is the monomer of proteins. |
| Protein | A large molecule made out of many amino acid molecules bonded together. |
| Lipids | A type of fat. It is a large molecule made up of glycerol and three fatty acids (triglyceride) |
| Macromolecule | A large molecule (ex. proteins, lipids, carbohydrates) |
| Enzyme | A type of protein that causes a reaction to occur quickly because it lowers the activation energy of a reaction. |
| Activation Energy | The energy required for a reaction to take place |
| The main function of a carbohydrates | Energy for our cells |
| The main functions of lipids | Thermal insulation, source for biofuel, makes up cell membranes, cushion organs, long term energy |
| The main functions of proteins | structure, enzymes, immune system, muscles |
| What determines a protein's function? | Its shape (how it folds) |
