Which of the following statements is false?

a. Metabolism is the sum of all the reactions in the body.

b. Anabolic pathways are exergonic and release energy.

c. Catabolic pathways break larger substances into smaller substances.

d. The body “pays for” anabolic reactions with the energy from catabolic reactions.

Expert Solution & Answer

Summary Introduction

Introduction:

All the living organisms require energy to carry out normal functions of the body. The energy obtained from different food sources are used by the body to create useful or essential products which help in growth and reproduction. Metabolism is the sum total of all reactions which takes place in the body and it includes both anabolism and catabolism.

Answer to Problem 1CYR

Correct answer:

Anabolic pathways are exergonic and release energy

Explanation of Solution

Justification/ Explanation for the correct answer:

Option ( b ) states that anabolic pathways release energy as they are exergonic. The statement is false because anabolism is building up a process where small molecules are combined to form a large or complex molecule. Anabolic pathways are endergonic as this reaction needs the energy to create bonds between small molecules. So, option ( b ) is correct.

Explanation for the incorrect answers:

Option (a) states that metabolism includes or refers to all the reactions which take place in the body. The statement is true as metabolism includes both anabolism, or building up process and catabolism, or breaking down process. So, it is an incorrect option.

Option (c) states that catabolic pathways include reactions which break down large complex substances into simpler ones. The statement is true because catabolism is a breaking down process which releases energy. So, it is an incorrect option.

Option (d) states that anabolic reactions get energy from catabolic reactions. The statement is true as the anabolic reactions require energy to create bonds and it is obtained from catabolic reactions which release energy by breaking chemical bonds. So, it is an incorrect option.

Hence, options (a), (c), and (d) are incorrect.

Conclusion

Thus, anabolic pathways are endergonic as it requires energy whereas catabolic pathways are exergonic as it releases energy.
