ENZYMES | An introduction to their structure and function
Miss Angler・14 minutes read
Enzymes are essential proteins that catalyze biological processes by breaking down or building up molecules, with specific conditions like pH and temperature affecting their function. Changes in these factors can denature enzymes, impacting their shape and function irreversibly, making it crucial to understand enzyme terminology for biology exams and tests.
Insights
- Enzymes are essential proteins that act as catalysts, accelerating biological processes by lowering activation energy and breaking down complex molecules into simpler forms.
- The functionality of enzymes is highly dependent on specific conditions like pH and temperature, with deviations from optimal ranges potentially leading to denaturation and irreversible changes in shape and function.

"Enzymes: Essential Catalysts in Biology"
- Enzymes are crucial in biology, running all processes in organisms.
- Enzymes are categorized as extracellular (secreted outside the cell) and intracellular (used inside the cell).
- Enzymes are globular proteins, reusable, sensitive to pH and temperature, and substrate-specific.
- Enzymes break down complex molecules into simpler ones based on their shape and substrate.
- Enzymes act as catalysts, speeding up reactions by providing activation energy.
- Enzymes have an active site that matches the substrate, leading to product formation.
- Enzymes can be used for anabolic (building up) or catabolic (breaking down) reactions.
- Factors affecting enzymes include pH and temperature, with specific conditions for optimal function.
- Changes in pH or temperature can denature enzymes, altering their shape and function irreversibly.
- Understanding enzyme terminology is essential for exams and tests in biology.
