Lysosomes and Peroxisomes: Guardians of Cellular Waste Management
Lysosomes and Peroxisomes: Guardians of Cellular Waste Management Introduction Cells are the fundamental units of life, and their proper functioning depends on effective waste management systems. Two critical organelles, lysosomes and peroxisomes, play a pivotal role in maintaining cellular health by processing and eliminating waste. These structures ensure that cellular components are recycled, toxins are neutralized, and harmful byproducts are degraded....
Questions and Answers on Lysosomes and Peroxisomes: Cellular Waste Management
1. Describe the structure of lysosomes. Lysosomes are membrane-bound spherical vesicles containing hydrolytic enzymes. Their membranes protect the cell from the enzymes within, which are active in an acidic environment (pH ~5). 2. Explain the role of lysosomes in autophagy. Autophagy is the process by which lysosomes degrade and recycle cellular components, such as damaged organelles, to maintain cellular homeostasis. 3. What is...
