Golgi bodies, or Golgi apparatus, are cellular organelles responsible for modifying, sorting, and packaging proteins and lipids synthesized in the endoplasmic reticulum. They consist of flattened membranous sacs and play a crucial role in the secretion and intracellular transport of molecules. This is an MCQ on Golgi Apparatus – Structure […]
Glyoxysomes are specialized peroxisomes found in plant cells. They participate in lipid metabolism, converting stored lipids into carbohydrates during germination of seeds. Glyoxysomes contain enzymes like isocitrate lyase and malate synthase that enable this conversion in the glyoxylate cycle. This is an MCQ on Glyoxisomes Structure and Functions. | Cell […]
The endoplasmic reticulum (ER) is a cellular organelle involved in the synthesis, folding, and transport of proteins and lipids. It consists of a network of membranes within the cell, with rough ER studded with ribosomes for protein synthesis and smooth ER involved in lipid metabolism and detoxification. This is an […]
Ribosomes are cellular structures essential for protein synthesis. Composed of RNA and proteins, they read genetic instructions from mRNA and assemble amino acids into polypeptide chains. Found in both prokaryotic and eukaryotic cells, ribosomes play a crucial role in the translation of genetic information into proteins. This is an MCQ […]
The nucleolus is a distinct substructure within the cell nucleus where ribosomal RNA (rRNA) synthesis occurs. It plays a crucial role in assembling ribosomes, essential for protein synthesis. The nucleolus is vital for cellular functions, contributing to overall cell health. This is an MCQ on Nucleolus Structure and Functions. | […]
