33. Which of the following is the major immediate function of carbohydrate breakdown by cells?
Answer: B
Releasing energy
The major immediate function of carbohydrate breakdown by cells is to release energy. This process is vital for fueling various cellular activities and maintaining metabolic functions.
A) Repairing tissues
Repairing tissues is primarily a function of proteins and amino acids rather than carbohydrates. While carbohydrates can provide energy for the processes that support tissue repair, they are not directly involved in the repair mechanisms themselves.
B) Releasing energy
Releasing energy is the correct answer as carbohydrates are metabolized through glycolysis and other pathways to produce ATP, the energy currency of the cell. This energy is essential for a multitude of cellular processes.
C) Forming enzymes
Forming enzymes is a function primarily associated with proteins and not carbohydrates. Enzymes are proteins that catalyze biochemical reactions, and while carbohydrates can play a role in cellular structure, they do not directly contribute to enzyme formation.
D) Dissolving fats
Dissolving fats is not a direct function of carbohydrates. While carbohydrates can influence lipid metabolism, their primary role is not in fat dissolution but rather in energy production through their own metabolic breakdown.
Conclusion
The correct answer, releasing energy, underscores the fundamental role of carbohydrates in cellular respiration and energy metabolism. Other options, such as repairing tissues, forming enzymes, and dissolving fats, do not accurately reflect the immediate function of carbohydrate breakdown, as they relate to different biological processes and macromolecules.
