Concept:The process shown in the diagram is respiration, which releases energy inside living cells.
Explanation:The diagram illustrates the breakdown of glucose in a living animal cell to release energy.
Glucose combines with oxygen in this process to produce energy, carbon dioxide, and water.
The overall chemical equation is:
C6H12O6+6O2→6CO2+6H2O+energy.
This respiratory process is carried out by the mitochondrion.
The mitochondrion is known as the powerhouse of the cell because it generates most of the cell's energy in the form of ATP.
The nucleus stores genetic material, the Golgi body modifies and packages proteins, and the cytoplasm is the jelly-like fluid where many metabolic reactions occur, but none of these is the main site of respiration.
Therefore, the process occurs in the mitochondrion.
Answer:B. Mitochondrion
