The cell membrane consists of a phospholipid bilayer with embedded proteins. The fluid mosaic model describes its dynamic structure.
Mitochondria are called the powerhouse because they produce most of the cell's ATP through oxidative phosphorylation and the Krebs cycle.
Rough endoplasmic reticulum has ribosomes on its surface for protein synthesis, while smooth ER is involved in lipid synthesis and detoxification.
The Golgi apparatus modifies, sorts, and packages proteins and lipids received from the ER for secretion or delivery to other organelles.
Lysosomes contain hydrolytic enzymes that break down proteins, lipids, nucleic acids, and carbohydrates. They maintain an acidic pH of about 4.8.
The nuclear envelope is a double membrane with nuclear pores that regulate transport of molecules between nucleus and cytoplasm.
Centrioles organize the mitotic spindle during cell division. They are found in animal cells and form the basis of cilia and flagella.
Ribosomes consist of ribosomal RNA (rRNA) and proteins. They are the site of protein synthesis, translating mRNA into polypeptide chains.
Singer and Nicolson proposed the fluid mosaic model in 1972, describing the cell membrane as a dynamic structure with floating proteins in a lipid bilayer.
Peroxisomes contain enzymes that break down fatty acids through beta-oxidation and detoxify hydrogen peroxide using the enzyme catalase.
