Histone proteins are highly alkaline proteins found in eukaryotic cell nuclei. They form the core around which DNA wraps to form nucleosomes, the basic units […]
The rough endoplasmic reticulum (RER) is a cellular organelle characterized by its studded appearance due to ribosomes attached to its surface. It plays a vital […]
The smooth endoplasmic reticulum (SER) lacks ribosomes on its surface and is involved in lipid synthesis, detoxification, and calcium storage within eukaryotic cells. It plays […]
MCQ on Protein Function: Proteins serve diverse roles in living organisms, including enzymatic catalysis, structural support, transport of molecules, immune defense, and cell signaling. They […]
Lipids serve diverse functions, including energy storage, insulation, and cushioning. They form structural components of cell membranes, contribute to signaling molecules, and aid in nutrient […]
Fatty acids serve vital roles in the body, functioning as energy sources, structural components of cell membranes, and precursors to signaling molecules. Essential fatty acids […]
Enzymes are biological catalysts that accelerate chemical reactions in living organisms. They facilitate processes such as metabolism, DNA replication, and digestion by lowering activation energy. […]
A peptide bond is a covalent linkage between the carboxyl group of one amino acid and the amino group of another. Formed during protein synthesis […]
