In eukaryotic cells, what is the primary function of mitochondria?
A
They synthesize proteins for secretion by translating mRNA on bound ribosomes.
B
They package and sort proteins into vesicles for transport to the plasma membrane or lysosomes.
C
They store the cell’s genetic information and regulate transcription.
D
They generate ATP by oxidizing nutrients through the citric acid cycle and oxidative phosphorylation.
Verified step by step guidance1
Identify the organelle in question: mitochondria are membrane-bound organelles found in eukaryotic cells.
Recall the main functions of mitochondria, which are often described as the 'powerhouses' of the cell.
Understand that mitochondria generate energy by converting nutrients into ATP, the cell's energy currency, through processes like the citric acid cycle and oxidative phosphorylation.
Differentiate mitochondria from other organelles: protein synthesis is mainly done by ribosomes, packaging and sorting by the Golgi apparatus, and genetic information storage by the nucleus.
Conclude that the primary function of mitochondria is to produce ATP by oxidizing nutrients, supporting cellular energy needs.
