The process of respiration takes place in [A] Mitochondria. Mitochondria are specialized organelles found in eukaryotic cells responsible for cellular respiration. During respiration, mitochondria use oxygen to break down glucose molecules through a series of biochemical reactions, ultimately generating ATP (adenosine triphosphate), the cell’s primary energy source. This process occurs in the inner mitochondrial membrane and involves the electron transport chain and oxidative phosphorylation.
Unlike chloroplasts, which are involved in photosynthesis, and ribosomes, which are responsible for protein synthesis, mitochondria play a crucial role in aerobic respiration, enabling cells to produce energy efficiently. Lysosomes, on the other hand, are involved in intracellular digestion and the recycling of cellular waste, while ribosomes function in protein synthesis. However, it is within the mitochondria that the complex biochemical processes of respiration occur, highlighting their significance in cellular metabolism and energy production.
