Metabolic Pathway Flashcards
Enzyme
Biological catalyst that speeds up a reaction
Precursor or intermediates
Starting molecules or molecules within a pathway that are required for the next step in a metabolic pathway
Metabolic pathway
Series of chemical reactions when the product/substrate of one is the substrate of next. Gene codes for one enzyme. Each enzyme catalyse one specific reaction due to unique shape
Mutation definition and cause
Change in the base sequence in DNA, cause by MUTAGENS - uv radiation, smoking and errors during dna replication
Gene influence on metabolic pathway
Gene codes for ENZYME that CATALYSES the reactions in the pathway
If Gene is mutated
Resulting enzyme NOT functional and END product cannot be made.
Mutation in gene affect on enzyme shape and amino acid
Enzyme will have DIFFERENT SHAPE and contain different amino acid
