GCSE School level biology revision notes: Digestive system, its function and role of enzymes
SITEMAP Use page sub-index, take time to study the content on ENZYMES
Metabolic chemistry - Our digestive system and ENZYMES - their structure, function and optimum conditions of these amazing molecular biological catalysts, and enzyme reaction investigations * See also Enzymes and Biotechnology (GCSE/IGCSE chemistry notes) * Sub-index for enzymes and digestive system pages 1. Introduction - Metabolism, what are enzymes? why so important in living system? 2. How do enzymes work? 'Key and lock' mechanism theory - supported by scientific evidence 3. Effect of changing concentration of the substrate for an enzyme catalysed reaction? 4. Effect of changing pH - What is the optimum pH of an enzyme catalysed reaction? 5. Effect of temperature - What is the optimum temperature for an enzyme catalysed reaction? 6.
Introduction to methods of measuring enzyme activity
(see 7. and 8. for method details)
9. Details of how the digestive system works and the role of gut bacteria and fungi (then 10.) 10. A summary of the human body's enzyme production sites and the digestive system 11. Enzymes and digestion - big protein/carbohydrate/fat molecules to small molecules! 12. Enzymes - synthesis of carbohydrates/proteins/lipids - small molecules to big molecules! 13. Doc Brown's unoriginal bread recipe! - excellent example of domestic enzyme technology! 14. Enzymes and Biotechnology (GCSE/IGCSE level chemistry notes) See also Surfaces for the exchange of substances in animal organisms (includes small intestine) WHERE NEXT?
