Multiple Choice
What is the primary function of a mitochondrion in a eukaryotic cell?
A
To store genetic information as the cell’s main repository of DNA
B
To generate ATP through cellular respiration (e.g., oxidative phosphorylation)
C
To synthesize proteins by translating mRNA on ribosomes
D
To modify, sort, and package proteins for secretion via the Golgi apparatus
Verified step by step guidance1
Identify the main organelles involved in the options given: mitochondrion, nucleus, ribosomes, and Golgi apparatus.
Recall the primary function of the mitochondrion, which is often called the 'powerhouse of the cell' because it produces energy.
Understand that mitochondria generate ATP (adenosine triphosphate), the cell's main energy currency, through a process called cellular respiration, specifically oxidative phosphorylation.
Recognize that storing genetic information is primarily the role of the nucleus, synthesizing proteins is the role of ribosomes, and modifying and packaging proteins is the role of the Golgi apparatus.
Conclude that the correct function of the mitochondrion is to generate ATP through cellular respiration.
