Cards in this deck (18)
- 1Organicmolecules that have a high proportion of carbon atoms
- 2inorganica molecule or ion that has no more than one carbon atom
- 3dipolea polar molecule, with a positive and a negative charge separated by a very small distance
- 4hydrogen bondthe weak attractive force between a hydrogen atom with a partial positive charge and an atom with a partial negative charge, usually oxygen or nitrogen
- 5monosaccharidean individual sugar molecule
- 6isomersmolecules with the same chemical formula but a different structural formula i.e. a different arrangement of atoms
- 7polymera large molecule comprising repeated units (monomers) bonded together
- 8ester bondan oxygen atom joining two atoms, one of which is a carbon atom attached by a double bond to another oxygen atom
- 9peptide bondthe chemical bond formed by a condensation reaction between the amino group of one amino acid and the carboxyl group of another
- 10activation energythe minimum energy required to bring about a chemical reaction; lowered by the presence of enzymes
- 11chemoautographan organism that uses chemical energy to make complex organic molecules
- 12condensation reactionchemical process in which two molecules combine to form a more complex molecule, with the elimination of a molecule of water
- 13hexosea monosaccharide containing six carbon atoms
- 14hydrolysisthe breaking down of large molecules into smaller molecules, by the addition of a molecule of water
- 15metabolismall the organism's chemical processes, comprising anabolic and catabolic pathways
- 16monomersingle repeating unit of a polymer
- 17pentosea monosaccharide containing containing five carbon atoms
- 18triosea monosaccharide containing three carbon atoms
