  49. 199.Read the following passage: "The process of cellular respiration is how organisms convert glucose into energy (ATP). This complex process occurs in three main stages: glycolysis, the Krebs cycle (also known as the citric acid cycle), and oxidative phosphorylation. Glycolysis, the first stage, takes place in the cytoplasm and breaks down glucose into pyruvate, producing a small amount of ATP. The pyruvate then enters the mitochondria, where the Krebs cycle further breaks it down, releasing carbon dioxide and generating more ATP and electron carriers. Finally, oxidative phosphorylation, which includes the electron transport chain, occurs on the inner mitochondrial membrane, producing the vast majority of ATP through a series of redox reactions. This entire process is essential for sustaining life functions." Where does the majority of ATP production occur during cellular respiration?Paragraph Comprehension (PC)
  50. 200.Read the following passage: "The human immune system is a complex network of cells, tissues, and organs that work together to protect the body from pathogens like bacteria, viruses, fungi, and parasites. It is broadly categorized into two main branches: the innate immune system and the adaptive (or acquired) immune system. The innate immune system provides immediate, non-specific defense against invaders. It includes physical barriers like skin, chemical barriers like stomach acid, and various immune cells such as phagocytes that engulf and destroy foreign particles. The adaptive immune system, in contrast, is highly specific and has a 'memory,' meaning it can recognize and respond more effectively to pathogens it has encountered before. This memory is crucial for long-term immunity, for example, after vaccination or recovery from an infection. Both systems are vital for maintaining health, with the innate system providing the first line of defense and the adaptive system offering targeted, long-lasting protection." Which of the following characteristics is unique to the adaptive immune system, as described in the passage?Paragraph Comprehension (PC)
