Study Notes
Enzyme Functions and Properties
- The main function of enzymes in living organisms is to catalyze metabolic reactions, increasing reaction rates and efficiency.
Enzyme Denaturation
- Denaturation of enzymes occurs under conditions such as high temperatures, extreme pH, and exposure to organic solvents or heavy metals, causing the loss of their native structure and function.
Enzyme Solubility
- The property of enzymes that allows them to dissolve in water, salt, glycerol, and alcohol is their amphipathic nature, having both hydrophilic and hydrophobic regions.
Factors Affecting Enzyme Activity
- Enzyme activity depends on factors such as temperature, pH, substrate concentration, and the presence of inhibitors or activators.
Enzymes in the Human Body
- Enzymes aid the human body by facilitating various physiological processes, including digestion, energy production, and detoxification.
Factors Not Affecting Enzyme Activity
- The factor that does not affect enzyme activity is light.
Enzyme Reactivation
- Enzymes remain unchanged after a reaction due to their property of catalysis, allowing them to react multiple times without being consumed.
Enzyme-Related Diseases
- The disease NOT associated with markers involving enzymes is hypertension.
