NEET PG DENTAL EXAM

Detailed explanation-1: -The answer is enzymes. Enzymes in our bodies are catalysts that speed up reactions by helping to lower the activation energy needed to start a reaction. Each enzyme molecule has a special place called the active site where another molecule, called the substrate, fits.

Detailed explanation-2: -The statement is True. The statement is correct because enzymes significantly enhance the speed of chemical reactions and thus bind with the substrate or reactant molecules to form the product. They serve as biological catalysts that typically reduce the activation energy so that the product can be formed faster.

Detailed explanation-3: -Enzymes and catalysts both affect the rate of a reaction. In fact, all known enzymes are catalysts, but not all catalysts are enzymes. The difference between catalysts and enzymes is that enzymes are largely organic in nature and are bio-catalysts, while non-enzymatic catalysts can be inorganic compounds.
