11. Aerobic Respiration
Mitochondria
Multiple Choice
In eukaryotic cells, the primary function of mitochondria is to:
A
Package and sort proteins into vesicles for transport to the plasma membrane
B
Store and transmit genetic information as the cell’s main repository of DNA
C
Generate ATP through aerobic cellular respiration (including oxidative phosphorylation)
D
Synthesize proteins for secretion via ribosomes on the rough endoplasmic reticulum
Verified step by step guidance1
Identify the main organelles involved in the options given: mitochondria, Golgi apparatus, nucleus, and rough endoplasmic reticulum (ER).
Recall the primary function of mitochondria, which is often described as the 'powerhouse of the cell,' responsible for producing energy.
Understand that mitochondria generate ATP (adenosine triphosphate) through aerobic cellular respiration, a process that includes glycolysis, the citric acid cycle, and oxidative phosphorylation.
Recognize that packaging and sorting proteins into vesicles is the function of the Golgi apparatus, not mitochondria.
Note that storing and transmitting genetic information is the role of the nucleus, and synthesizing proteins for secretion is primarily done by ribosomes on the rough ER.
