Enzyme Mnemonic (this topic one of the importance back bone In biochemistry )
Enzyme Mnemonics: Lock and Key Model: Jelly (Enzyme) fits into the lock (Substrate) Induced Fit Model: Just (Enzyme) adjusts and alters shape for Substrate Active Site: Always has a unique shape and charge to attract Substrate Catalytic Site: Contains amino acids that speed up reaction and lower energy barrier Allosteric Site: Affects enzyme activity, binding of one molecule can change shape and effect other sites Lock is released: After reaction, product is released and enzyme returns to original shape Biochemistry: Heterogeneous Catalysis: H (Heterogeneous) means different phases, catalyst provides new path for reaction, increases speed, not used up in reaction, can be solid, liquid or gas. Enzymes: Act as catalysts in biological systems, speed up reactions, lower energy barrier, highly specific ATP: Adenosine triphosphate, energy currency of the cell, stores and transports energy within cells Importance of pH, Temperature and Salt Concentration: Optimal pH and temperature increase enzyme activity, high salt concentration can inhibit enzyme activity.
