Enzyme Vocabulary Exercise Cheat Sheet
- Enzymes as Biological Catalysts - Enzymes are nature's tiny sprinters that speed up chemical reactions without getting consumed. They ensure our digestion and metabolism run at lightning speed, keeping us full of energy.
- Active Site Specificity - Each enzyme boasts a unique active site where substrates snugly fit like puzzle pieces, guiding only the right reactions. This lock-and-key or induced-fit magic ensures reactions happen with pinpoint accuracy.
- Optimal Conditions - Enzyme efficiency peaks at their favorite temperature and pH, but stray too far and they denature like a bad pancake. Understanding these sweet spots helps in lab experiments and industrial processes alike.
- Cofactors and Coenzymes - Some enzymes need sidekicks called cofactors - metal ions or organic helpers like vitamins - to hit their full potential. Without these partners, the enzymatic party just can't start.
- Enzyme Classification - Enzymes are sorted into six elite teams: oxidoreductases, transferases, hydrolases, lyases, isomerases, and ligases based on their reaction type. Knowing these groups helps you predict how each enzyme behaves.
- Enzyme Kinetics - Enzyme kinetics zooms in on the speed of reactions, spotlighting the Michaelis-Menten equation that links substrate concentration to reaction rate. These curves reveal enzyme efficiency and help tailor experiments.
- Enzyme Inhibitors - Inhibitors are molecules that can cramp an enzyme's style by binding to the active site (competitive) or elsewhere (non-competitive) to slow things down. This knowledge is key for designing drugs that tweak enzyme activity.
- Allosteric Regulation - Allosteric sites are enzyme hidden hot spots where molecules can bind to ramp up or dial down activity. This on-off switch is crucial for fine-tuning metabolic pathways.
- Feedback Inhibition - In feedback inhibition, the end product of a pathway mob bosses earlier enzymes to stop working, keeping the cell's chemistry in balance. It's like a self-regulating thermostat for metabolism.
- Biotech and Medical Applications - From crafting life-saving drugs to brewing beer, enzymes are biotech heroes in laboratories and industries. Their diverse uses span disease diagnosis, genetic engineering, and environmental cleanup.
