Chapter 23: Problem 61

Enzymes are large proteins. a. What is the function of enzymes? b. Are all proteins enzymes?

Short Answer

Expert verified
Answer: Enzymes act as biological catalysts, speeding up the rate of biochemical reactions without being consumed or altered themselves. Their main function is to lower the activation energy required for a reaction, making it easier for reactants to transform into products. Not all proteins are enzymes; while enzymes are a type of protein, proteins have various roles in living organisms, such as structural, transport, and hormonal functions.

Step by step solution

01

a. Function of enzymes

Enzymes are act as biological catalysts, which means they speed up the rate of biochemical reactions happening in the cells without being consumed or altered themselves. Their main function is to lower the activation energy required for a reaction to occur, thus making it easier for the reactants to transform into products. Enzymes achieve this by binding to reactants, also known as substrates, forming an enzyme-substrate complex. This process helps to stabilize the transition state, eventually leading to the formation of the products and the release of the enzyme, which can then participate in another reaction.
02

b. Are all proteins enzymes?

No, not all proteins are enzymes. Proteins are large biomolecules composed of amino acids, and they play various crucial roles in living organisms. While enzymes are indeed a type of protein, not all proteins act as enzymes (catalysts). There are structural proteins, such as collagen and keratin, which provide support and shape to cells and tissues; transport proteins, like hemoglobin, that carry substances through the body; and hormonal proteins, such as insulin, that regulate blood sugar levels, among many other examples. In conclusion, enzymes represent just one important category of proteins, each serving various biological functions.
