Question

Which of the following statement is correct?

• A. Biocatalysts accelerate the rate of a given metabolic reaction
• B. Biocatalysts are generally proteins
• C. Enzyme catalysts differ from inorganic catalysts
• D. All of the above

Answer 1

The correct option is D All of the above

Biocatalysts or enzymes accelerate the rate of a given metabolic reaction. The enzymes lower the amount of activation energy required to start the reaction. Activation energy is defined as the minimum amount of extra energy required by a reacting molecule to get converted into the product(s). Enzymes regulate the speed and specificity of reaction without being used up during the reaction.
Biocatalysts or enzymes are generally proteinaceous in nature.
Inorganic catalysts differ from enzyme catalysts in being inorganic, less specific and less sensitive to pH and temperature changes. The catalytic action of inorganic catalysts generally cannot be regulated by any regulatory molecule. For example - platinum.
