- PROTEINS AND MUTATIONS
- Grouping organisms
- Proteins=amino acid chains. Have different functions like structural, hormonal and carrier -
- proteins own amino acid order and numer making them different
- Enymes
- Enzymes are biological catalysts (catalyze photo and protein synthesis + respiration)
- Lock and key theory: substrate molecule fits into active site of enzyme
- Optimum temp and pH different for each enzyme- anything away from this will slow down the reaction.
- Q10=rate at higher temperature / rate at lower temperature [10 degree difference]
- Q10 measure hows rate of reaction is affected by temperature
- Mutations
- May occur spontaneously or radiation. - may lead to different proteins produced - usually harmful doesn't have to be - maybe advantage
- Genes are the same but not proteins are not the same. Genes are switched off in different cells
- Gene mutations alter/prevent protein through changing DNA base code and so changing the order of amino acids
- Grouping organisms
