Questions: ATI TEAS Version 7 - Science Question: 28 of 50 Which of the following parts of the eukaryotic cell is responsible for making ATP? Nucleus Mitochondria Lysosome Centrioles

The answer is the second one: Mitochondria.

Explanation for each option:

• Nucleus: The nucleus is the control center of the cell, responsible for storing the cell's genetic material (DNA) and coordinating activities like growth, metabolism, and reproduction. It is not involved in ATP production.

• Mitochondria: Mitochondria are known as the "powerhouses" of the cell. They are responsible for producing ATP (adenosine triphosphate) through the process of oxidative phosphorylation during cellular respiration. This makes them the correct answer.

• Lysosome: Lysosomes are organelles that contain digestive enzymes. They break down waste materials and cellular debris. They do not produce ATP.

• Centrioles: Centrioles are involved in cell division and help in the formation of the spindle fibers that separate chromosomes during mitosis. They do not have a role in ATP production.

In summary, mitochondria are the organelles responsible for making ATP in eukaryotic cells.
