Question

in the cell, which organelle has the function of using oxygen in the breakdown of glucose, releasing energy and carbon dioxide?
vacuole
nucleus
cell membrane
mitochondria
in elite athletes which organelle will be more prevalent in their muscle cells?
chloroplast
lysosome
mitochondria
ribosomes

Explanation:

Mitochondria are the power - houses of the cell. They carry out cellular respiration, using oxygen to break down glucose, releasing energy (in the form of ATP) and carbon dioxide. Elite athletes need more energy for their high - intensity activities, and since mitochondria produce energy, they are more prevalent in the muscle cells of elite athletes.

Answer:

1. D. mitochondria
2. C. mitochondria
