Enzymes are proteins that catalyze reactions without being consumed, having an active center where reactions occur and can be highly specific to substances, needing cofactors for optimal function. Enzyme activity is influenced by factors like temperature, pH, substrate concentration, and interactions with other substances.
Insights
- Enzymes are proteins that act as catalysts, speeding up reactions without being used up themselves, and can perform actions repeatedly without replacement.
- Enzyme activity is influenced by various factors such as temperature, pH, substrate concentration, and interactions with other substances, which can affect their efficiency and effectiveness significantly.

"Enzymes: Catalysts of Biological Reactions"
- Enzymes are proteins that catalyze processes, accelerating them without being consumed themselves.
- Enzymes have an active center where reactions occur, allowing them to split molecules like maltose into glucose.
- Enzymes can repeatedly perform actions without needing replacement, with some capable of acting a thousand times per second.
- The substance on which an enzyme acts is called the substrate, while the resulting substances are the products.
- Enzymes can be very specific to certain substances, following the key-lock principle for optimal function.
- Enzymes often require cofactors or coenzymes to function effectively, aiding in activation or activity.
- Enzyme activity is influenced by factors like temperature, pH, substrate concentration, and interactions with other substances, impacting their efficiency and effectiveness.
