Praxis 5005 Practice Test Practice Question
Which of the following is the major immediate function of carbohydrate breakdown by cells?
Correct Answer: B
Rationale: Carbohydrate breakdown primarily serves to release energy, which is essential for various cellular processes. This energy is harnessed in the form of ATP, enabling cells to perform functions like muscle contraction and biosynthesis.
Option A, repairing tissues, is a longer-term process that relies on proteins and other nutrients rather than immediate energy from carbohydrates. Option C, forming enzymes, involves amino acids and is not a direct function of carbohydrate metabolism. Option D, dissolving fats, pertains to lipid metabolism and is unrelated to the primary role of carbohydrates in energy production.
