Cells contain several types of organelles, each with a specific function:
Mitochondria: Known as the powerhouse of the cell, they generate ATP through cellular respiration. Endoplasmic Reticulum (ER): There are two types – rough ER (with ribosomes) involved in protein synthesis, and smooth ER involved in lipid synthesis and detoxification. Golgi Apparatus: Modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles. Lysosomes: Contain digestive enzymes to break down waste materials and cellular debris. Peroxisomes: Involved in lipid metabolism and detoxification of harmful substances. Ribosomes: Sites of protein synthesis, either free in the cytoplasm or attached to the rough ER. Cytoskeleton: A network of protein filaments and tubules that provides structural support and facilitates cell movement.
