Chapter 14, Problem 14.54QP

Interpretation Introduction

Interpretation:

The concentrations of enzymes in cells are usually quite small and what is the biological significance of this fact has to be explained.

Concept introduction:

Catalyst: A substance or a compound which promotes the rate of a chemical reaction is said to be catalyst.  Catalysts are classified into two types.  They are homogeneous catalysts and heterogeneous catalysts.

Homogeneous catalysis: In a chemical catalysis reaction solution by a soluble catalyst is said to be homogeneous catalysis.

Heterogeneous catalysis: In a chemical catalysis reaction, the phases of reactant and catalyst are different.

Enzyme: Macromolecular biological species are said to be enzyme and which acts as a catalyst in many chemical reactions.
