Worked practice questions

What name is given to the reactions that break food down to obtain energy?

  1. Catabolic reactions
  2. Anabolic reactions
  3. Synthetic reactions
  4. Buffering reactions
Show answer and solution

Correct answer: A. Catabolic reactions

1. Metabolism splits into two opposite families of reaction. 2. The reactions governing the breakdown of food to obtain energy are called catabolic reactions. 3. Anabolic reactions run the other way, building larger molecules instead. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 24 "Metabolism and Nutrition", section 24.1 | Overview of Metabolic Reactions_

What do anabolic reactions do with the energy that catabolic reactions release?

  1. Store it as body heat
  2. Excrete it in the urine
  3. Return it to the food
  4. Build larger molecules
Show answer and solution

Correct answer: D. Build larger molecules

1. Catabolic and anabolic reactions are coupled through the energy they trade. 2. Anabolic reactions use the energy produced by catabolic reactions to synthesise larger molecules. 3. Ideally the energy used and the energy produced would balance each other. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 24 "Metabolism and Nutrition", section 24.1 | Overview of Metabolic Reactions_

What does a negative net energy change mean for the body?

  1. It stores surplus energy
  2. It uses stored energy
  3. It halts all metabolism
  4. It doubles its heat output
Show answer and solution

Correct answer: B. It uses stored energy

1. Net energy change compares what catabolism releases with what anabolism spends. 2. When catabolic reactions release less energy than anabolic reactions use, the change is negative. 3. The body then draws on stored energy to make up the shortfall. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 24 "Metabolism and Nutrition", section 24.1 | Overview of Metabolic Reactions_
