Mitochondria
Multiple Choice
What is the primary purpose of mitochondria in eukaryotic cells?
A
To synthesize lipids and detoxify drugs primarily through membrane-bound enzymes
B
To generate ATP through cellular respiration (e.g., oxidative phosphorylation)
C
To package and modify proteins for secretion via the endomembrane system
D
To store the cell’s genetic information and regulate transcription
Verified step by step guidance1
Identify the main functions of each organelle mentioned in the options to understand their roles in the cell.
Recall that mitochondria are known as the 'powerhouses' of the cell because they generate energy in the form of ATP through cellular respiration.
Understand that ATP (adenosine triphosphate) is the primary energy currency used by cells to power various biological processes.
Recognize that other options describe functions of different organelles: lipid synthesis and detoxification relate to the smooth endoplasmic reticulum, protein packaging and modification relate to the Golgi apparatus, and genetic information storage and transcription regulation relate to the nucleus.
Conclude that the primary purpose of mitochondria is to generate ATP through cellular respiration, specifically processes like oxidative phosphorylation.
