Enzymes got intracellular enzymes and extra cellulare enzymes What are intracellular enzymes? It is produced and retained in the cell for the use of the cell itself. They are foind in? Cytoplasm mitochondria nucleus and chloroplasts Hers an example.. The enzyme oxydoreductase catylyses biological oxidation anc reduction in the mitochondri What ae extracellular enzynes? Enzymes whixh are produced in the cell but secreted from the cell to function externallu Synthesis of enzymes Remember that ribosomes r d sjtes of protein synthesi 6 sequences The info fr the aynthesis of enzymes is carried by DNA *the sequences of bases on the dma are codes to make proteinsb Dikir sequences of bases tu. Codes la, Sequencesbof bases In NUCLEUS DNA double helox unwinds n exposes its 2 atrands fir yhe synthesise of rna Rna is synthesised axxording to the instructin of dna Then messenger rna leaves nuckeus to tbe ribosome Then it attaches itself to the ribosome Ribosome atcs as workbench. Rna contains info of codes ft the synsis if amini acid Genetic infrmation trabalated into d primary structure of specidfojc progein Eaxh amino acid is bo ded to d enxt and as a resultm polypeptides is formed n ready to release to the cytoplasm PRODUCTION OF EXTRACELLUKAR ENZYMES
