Multiple Choice
In eukaryotic cells, cellular respiration (including the citric acid cycle and oxidative phosphorylation) primarily occurs in which organelle?
A
Lysosome
B
Mitochondrion
C
Nucleus
D
Golgi apparatus
Verified step by step guidance1
Identify the organelle responsible for cellular respiration in eukaryotic cells by recalling the main sites of metabolic processes.
Understand that cellular respiration includes the citric acid cycle and oxidative phosphorylation, which are key steps in energy production.
Recall that the mitochondrion is known as the 'powerhouse of the cell' because it generates ATP through these processes.
Recognize that lysosomes are involved in digestion, the nucleus stores genetic material, and the Golgi apparatus modifies and packages proteins, so they are not the primary sites of cellular respiration.
Conclude that the mitochondrion is the organelle where the citric acid cycle and oxidative phosphorylation primarily occur.
