1.1 Biochemical Unity Underlies biological diversity Flashcards
Metabolites
low-molecular-weight
molecules such as glucose and glycerol, referred to as
biological macromolecules
large molecules such as proteins and nucleic acids
biochemistry is the study of the chemistry of
life processes. These processes entail the interplay of two different
classes of molecules, which?
biological macromolecules, metabolites.
Members of both these classes of molecules are common, with minor
variations, to all living things.
Eukaryoten
hebben een kern in elke cel
Prokaryoten
hebben geen kern.
Divergente evolutie
different features, same species(common ancestors),same 3D structure, all cells have the same origin.
Convergente evolutie
similar features, different species(common ancestors), different 3D structure, product of natural selection.
homologs
similar ancestors
orthologs
similar ancestors different species
paralogs
similar ancestors different functions
