Question

Which option describes an enzyme

Answer 1

Enzymes are biological catalysts that speed up chemical reactions in living organisms. They are typically proteins and work by lowering the activation energy needed for a reaction to occur. This allows reactions to happen more quickly and efficiently at the moderate temperatures found in biological systems. Enzymes are highly specific, often catalyzing only one type of reaction or acting on a specific substrate. They can also be regulated by various factors, including temperature, pH, and the presence of inhibitors or activators. Overall, enzymes play a crucial role in facilitating metabolic processes within cells.
