Multiple Choice
What is the primary function of mitochondria in eukaryotic cells?
A
Modify and package proteins for secretion via the endomembrane system.
B
Generate most cellular ATP through aerobic respiration (including oxidative phosphorylation).
C
Store genetic information as the cell’s main repository of chromosomal DNA.
D
Synthesize proteins by translating mRNA on cytosolic ribosomes.
Verified step by step guidance1
Identify the organelle in question: mitochondria are membrane-bound organelles found in eukaryotic cells.
Recall the main roles of mitochondria, which primarily involve energy metabolism rather than protein modification, genetic storage, or protein synthesis.
Understand that mitochondria generate energy by converting nutrients into ATP, the cell's main energy currency, through processes like aerobic respiration and oxidative phosphorylation.
Differentiate mitochondria from other organelles: for example, the Golgi apparatus modifies and packages proteins, the nucleus stores genetic information, and ribosomes synthesize proteins.
Conclude that the primary function of mitochondria is to generate most cellular ATP through aerobic respiration, providing energy necessary for various cellular activities.
