Step 1: Understand the function of ATP in eukaryotic cells. ATP (adenosine triphosphate) is the primary energy currency of the cell, used to power various cellular processes.
Step 2: Review the role of each organelle listed in the question. For example: The mitochondrion is known as the 'powerhouse of the cell' because it produces ATP through cellular respiration. The lysosome is involved in breaking down waste and cellular debris. The Golgi apparatus modifies, sorts, and packages proteins and lipids. The nucleus houses genetic material and controls cellular activities.
Step 3: Focus on the mitochondrion and its specific function. Cellular respiration occurs in the mitochondrion, where glucose and oxygen are used to produce ATP. This process includes glycolysis, the citric acid cycle, and oxidative phosphorylation.
Step 4: Eliminate the incorrect options based on their functions. Lysosomes, Golgi apparatus, and the nucleus do not produce ATP, so they can be ruled out.
Step 5: Conclude that the mitochondrion is the organelle responsible for producing ATP in eukaryotic cells, as it is directly involved in energy production through cellular respiration.
