Question

in the cell, which organelle has the function of using oxygen in the breakdown of glucose, releasing energy, and carbon dioxide?
a ribosomes
b golgi bodies
c mitochondria
d endoplasmic reticulum

Explanation:

To solve this, we analyze each organelle's function:

• Option A (ribosomes): Synthesize proteins, not involved in glucose breakdown with oxygen.
• Option B (golgi bodies): Modify, sort, and package proteins/lipids, not related to glucose breakdown.
• Option C (mitochondria): Known as the "powerhouse of the cell," they perform cellular respiration. In this process, glucose is broken down using oxygen, releasing energy (ATP) and carbon dioxide as a byproduct.
• Option D (endoplasmic reticulum): Involved in protein and lipid synthesis/transport, not glucose breakdown with oxygen.

Answer:

C. mitochondria
