FAQs on Enzymes Video Lecture - Biology for ACT

1. What are enzymes and how do they function in the body?
Ans. Enzymes are proteins that act as catalysts in biochemical reactions within the body. They work by speeding up the rate of a reaction without being consumed in the process.
2. How are enzymes named and classified based on their function?
Ans. Enzymes are typically named based on the substrate they act upon, with the suffix "-ase" added to the end. They are classified into six main groups - oxidoreductases, transferases, hydrolases, lyases, isomerases, and ligases - based on their specific function in catalyzing reactions.
3. What factors can affect the activity of enzymes in the body?
Ans. Enzyme activity can be influenced by various factors such as temperature, pH levels, substrate concentration, enzyme concentration, and the presence of inhibitors or activators.
4. Can enzymes be denatured and lose their function?
Ans. Yes, enzymes can be denatured and lose their function when exposed to extreme conditions such as high temperatures or extreme pH levels. This alters the enzyme's shape, preventing it from binding to its substrate effectively.
5. How are enzymes used in various industries and applications outside of the body?
Ans. Enzymes are widely used in various industries such as food production, pharmaceuticals, and biofuels. They are employed in processes like brewing, cheese making, and waste treatment, due to their ability to catalyze reactions effectively and efficiently.
