Multiple Choice
What is the primary function of mitochondria in eukaryotic cells?
A
To generate ATP through aerobic respiration, primarily via the citric acid cycle and oxidative phosphorylation
B
To synthesize proteins for secretion by translating mRNA on bound ribosomes
C
To modify and sort proteins for delivery to lysosomes or the plasma membrane
D
To package DNA into chromosomes and regulate transcription in the nucleus
Verified step by step guidance1
Identify the organelle in question: mitochondria are membrane-bound organelles found in eukaryotic cells.
Recall the main role of mitochondria: they are often called the 'powerhouses' of the cell because they produce energy.
Understand the process involved: mitochondria generate ATP (adenosine triphosphate) through aerobic respiration, which includes the citric acid cycle (Krebs cycle) and oxidative phosphorylation.
Differentiate mitochondria from other organelles: protein synthesis for secretion is done by ribosomes on the rough endoplasmic reticulum, protein modification and sorting occur in the Golgi apparatus, and DNA packaging and transcription regulation happen in the nucleus.
Conclude that the primary function of mitochondria is to generate ATP by converting energy from nutrients using oxygen-dependent processes.
