D
Golgi apparatus
Verified step by step guidance1
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 options. The mitochondrion is known as the 'powerhouse of the cell' because it produces ATP through cellular respiration. The nucleus houses genetic material and regulates cellular activities, but does not produce ATP. Lysosomes are involved in breaking down waste and cellular debris. The Golgi apparatus modifies, sorts, and packages proteins and lipids for transport but does not produce ATP.
Step 3: Focus on the mitochondrion's role in ATP production. Cellular respiration occurs in the mitochondrion, where glucose and oxygen are converted into ATP, water, and carbon dioxide. This process includes glycolysis, the citric acid cycle, and oxidative phosphorylation.
Step 4: Eliminate incorrect options based on their functions. Since the nucleus, lysosome, and Golgi apparatus do not produce ATP, the correct answer must be the mitochondrion.
Step 5: Confirm your understanding by recalling that the mitochondrion contains structures like the inner membrane and matrix, which are essential for ATP production during oxidative phosphorylation.
