MYP4 Science Glossary
ACTIVE SITE: The part of an enzyme where the chemical reactions occur.
AMINO ACID: A simple organic compound containing both a carboxyl (−COOH) and an amino (−NH 2) group. It is the monomer which forms a protein.
BACTERIA: Single celled organisms that lack a nucleus.
BIOMOLECULE: A molecule produced by a living organism.
BLUBBER: A thick layer of fat that helps animal keep a stable body temperature and also helps them float.
CARBOHYDRATE: An organic compound consisting of Carbon, Hydrogen and Oxygen
Source- Bread, pasta, potato, sugar.
Function- Good source of energy (fast and easy to break down)
Structure- O Monosaccharide (e.g. Glucose), O-O Disaccharide (e.g. Sucrose), O-O-O... Polysaccharides (e.g. Starch)
CLASSIFYING: A process of putting data into different groups depending on their similarities.
COMMUNICATING: Part of research when people discuss problems, share ideas and try to help each other by talking.
CONTROL VARIABLES: A variable that stays unchanged. For example: in an experiment of testing if the color of sunlight affects the colors of the petals of a flower, the temperature and the amount of water would be the controlled variable as it doesnt change
DENATURE: When an enzymes active sight changes and wont bond to the substrate. Usually caused by temperature or ph affecting the hydrogen bonds in the protein structure.
DIFFUSION:
ENZYME: A chemical, made of protein, which helps in digestion by breaking down the food (called substrate) into small pieces (called product).
For example: Enzyme = Pepsin, Substrate = Proteins, Product = Amino Acids
PARTIALLY PERMEABLE MEMBRANE:
