Molecules of Life

Macromolecules of Life

ActivationEnergy Amount of energy needed to initiate a chemical reaction
ActiveSite Specific location on an enzyme where a substrate binds
AminoAcid Small compounds made of CHNOS
Carbohydrate Compound composed of only CHO
Catalyst Suubstance which lowers the activation energy of a chemical reaction
ChemicalReaction Process or rearranging atoms and molecules into different substances
Enzyme Special protein that speeds up chemical reactions in biological processes
Lipid Molecules made mostly of CH, store lots of energy
Macromolecule Large molecules that are formed by joining smaller molecules
Molecule Compound in which atoms are held together by chemical bonds
NucleicAcid Complex macromolecules that store and transmit genetic information; CHNOPS
Nucleotide Repeating subunits of nucleic acids
Polymer Molecules made from repeating smaller units
Product Substances present at the end of a chemical reaction
Protein Compound made from amino acids, involved in every function of a living organism
Reactant Substances present at the start of a chemical reaction
Substrate Reactant(s) that bind with an enzyme
Monomer Basic unit of a larger molecule that appears repeatedly
Endothermic Reaction A chemical reaction that absorbs energy
Exothermic Reaction A chemical reaction that releases energy
Element Substance made from a single type of atom
Disaccharide a molecule consisting of two sugars
Monosaccharide a molecule of sugar with C:H:O in a 1:2:1 ratio
Polysaccharide long chain of sugars, examples include: starch, glycogen and cellulose
Photosynthesis process where solar energy is used to convert carbon dioxide and water into glucose and oxygen
Cellular Respiration process where sugar is burned by oxygen to make ATP and releases carbon dioxide and water as byproducts
