Multiple Choice
Which primary function is most directly associated with mitochondria in eukaryotic cells?
A
They synthesize proteins for secretion by translating mRNA on bound ribosomes.
B
They package DNA into chromosomes and control gene transcription in the nucleus.
C
They modify and sort proteins for delivery to lysosomes or the plasma membrane.
D
They generate most cellular ATP through oxidative phosphorylation during aerobic respiration.
Verified step by step guidance1
Identify the organelle mentioned in the question: mitochondria, which are found in eukaryotic cells.
Recall the primary function of mitochondria, which is related to energy production within the cell.
Understand that mitochondria generate ATP, the cell's main energy currency, through a process called oxidative phosphorylation.
Recognize that oxidative phosphorylation occurs during aerobic respiration, which requires oxygen to efficiently produce ATP.
Conclude that the most direct function of mitochondria is to generate most cellular ATP through oxidative phosphorylation during aerobic respiration.
