Indicate which statements are true. Correct all false statements by changing the underlined words.
__________ Lysosomes fuse with phagosomes to form peroxisomes.

검증된 단계별 안내
1
Step 1: Understand the key terms involved. Lysosomes are organelles containing digestive enzymes, phagosomes are vesicles formed around a particle engulfed by phagocytosis, and peroxisomes are organelles involved in lipid metabolism and detoxification, not formed by fusion of lysosomes and phagosomes.
Step 2: Analyze the statement: 'Lysosomes fuse with phagosomes to form peroxisomes.' This suggests that the fusion of lysosomes and phagosomes creates peroxisomes, which is incorrect based on cell biology knowledge.
Step 3: Recall the correct process: Lysosomes fuse with phagosomes to form phagolysosomes, which are responsible for digesting the engulfed material inside the phagosome.
Step 4: Identify the false word in the statement: 'peroxisomes' is incorrect and should be replaced with 'phagolysosomes' to make the statement true.
Step 5: Corrected statement: 'Lysosomes fuse with phagosomes to form phagolysosomes.' This accurately describes the cellular process involved in degradation of phagocytosed material.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Phagosome Formation

Phagosomes are vesicles formed when a cell engulfs particles, such as bacteria, through phagocytosis. They enclose the ingested material and later fuse with other organelles to degrade the contents.

Lysosome Function and Fusion

Lysosomes are organelles containing digestive enzymes that fuse with phagosomes to form phagolysosomes. This fusion allows the breakdown of engulfed particles, aiding in cellular digestion and defense.

Peroxisomes and Their Role

Peroxisomes are distinct organelles involved in lipid metabolism and detoxification of reactive oxygen species. They are not formed by fusion of lysosomes and phagosomes, which is a process specific to phagolysosome formation.
