Multiple Choice
Which organelle is commonly referred to as the "powerhouse of the cell" because it generates most cellular ATP through aerobic respiration?
A
Mitochondrion
B
Ribosome
C
Golgi apparatus
D
Lysosome
Verified step by step guidance1
Understand the function of each organelle listed: Ribosomes synthesize proteins, Golgi apparatus modifies and packages proteins, Lysosomes digest cellular waste, and Mitochondria generate energy.
Recall that ATP (adenosine triphosphate) is the main energy currency of the cell, produced primarily through aerobic respiration.
Identify which organelle is responsible for aerobic respiration and ATP production; this organelle contains its own DNA and has a double membrane.
Recognize that the mitochondrion is known as the 'powerhouse of the cell' because it generates most of the cell's ATP through the process of oxidative phosphorylation.
Conclude that among the options given, the mitochondrion is the organelle that fits the description of producing most cellular ATP.
