C
Endoplasmic reticulum
D
Mitochondrion
Verified step by step guidance
1
Step 1: Understand the function of ATP in cells. ATP (adenosine triphosphate) is the primary energy currency of the cell, used to power various biological processes.
Step 2: Recall the process of cellular respiration. Cellular respiration is the metabolic pathway that converts glucose and oxygen into ATP, carbon dioxide, and water.
Step 3: Identify the organelle responsible for cellular respiration. In eukaryotic cells, the mitochondrion is the organelle where cellular respiration occurs, specifically in its inner membrane and matrix.
Step 4: Compare the functions of the other organelles listed. The Golgi apparatus is involved in protein modification and transport, lysosomes are responsible for breaking down waste materials, and the endoplasmic reticulum is involved in protein and lipid synthesis. None of these are directly involved in ATP production.
Step 5: Conclude that the mitochondrion is the correct answer because it is the organelle specialized for ATP production through cellular respiration in eukaryotic cells.
