Golgi Apparatus

Golgi Complex / Golgi Apparatus

Golgi apparatus is found in all types of eukaryotic cells except the mammalian RBCs. It is absent in prokaryotes. Golgi apparatus are small sacs which are responsible for transporting, modifying and packaging proteins and lipids.

The golgi apparatus was discovered by Camillo Golgi in 1898. He discovered them in the nerve cells. Golgi apparatus has a system of outer flattened cisternae which appears as parallel membranes in the form of an ellipse. 

There are two faces known as cis and trans face of golgi apparatus. The cis face lies near the rough endoplasmic reticulum and the trans face lies near to the cell membrane. Substances from the rough endoplasmic reticulum enter through the cis face for processing and they exit from the trans face in the form of smaller vesicles.

Functions:
  • Packaging center of cell.
  • Proteins are processed and sorted for their transport.
  • Lipid processing.
  • Secretory proteins like hormones are packed into secretory vesicles for their exocytosis.

  Previous Year Questions (PYQ's) 1. From the following statements,                                                                                         (DEC 2016) a) Hydrogen, Deuterium and Tritium differ in the number of protons. b) Hydrogen, Deuterium and Tritium differ in the number of neutrons. c) Both Deuterium and Tritium are radioactive and decay to hydrogen and deuterium respectively. d) Tritium is radioactive and decays to helium. e) Carbon-14 decays to Nitrogen-14. f) Carbon-14 decays to Carbon-13. Pick the combination with all correct statements. A) a, b and f      B) b, d and e C) a, c and d      D) c, e and f Ans. B - b, d and e Explanation: Hydrogen, deuterium and tritium are isotopes. Isotopes differ in the number of neutrons  and hence statement "b" is correct. Deuterium is non-radioactive but tritium is radioactive. Tritium shows β decay and tritium decays to helium and hence statement "d" is also correct. Carbon-14 also shows β decay and c

1.     Heredity and Evolution Introduction: Basic unit of life is cell. Controlling center of cell is nucleus. Inside nucleus there are chromosomes. Chromosomes are made up of DNA. Segment of DNA is called as gene. ✱ Heredity and Hereditary Changes: Heredity: Transfer of characters from one generation to another via genes. Johann Gregor Mendel - Father of modern genetics. Hugo de Vries - Mutation Theory (1901). Walter and Sutton - Observed paired chromosomes in cells of grasshopper. Ostwald Avery, Maclyn McCarthy and Colin MacLeod - Except viruses, all living organisms have DNA as genetic material (1944). Francois Jacob and Jack Monad - Proposed a model for process of protein synthesis. Science of heredity is useful for: Diagnosis, treatment and prevention of hereditary disorders. Production of hybrid varieties of animals and plants. In industrial processes in which microbes are used. ✱ Structure of DNA (Deoxyribo Nucleic Acid) Chromosomes are made up of DNA. Chromosomes are always in

  2. Life Processes in Living Organisms - Part I ✱ Energy from different food components: Various organ-systems perform their functions in human body. Digestive system, respiratory system, circulatory system, excretory system, nervous system. All these system require energy. Energy is obtained from food. Food contains nutrients like carbohydrates, proteins, fats. For obtaining energy only nutrients are not sufficient, but oxygen is also necessary. All these foodstuff and oxygen are transported up to the cell via a circulatory system. 1. Carbohydrates: Sources of carbohydrates: Milk, fruits, jaggary, cane sugar, vegetables, potatoes, sweet meats and cereals like wheat, maize, ragi, jowar, millet, rice etc. 1 gm of carbohydrate = 4 Kcal of energy (Kcal = Kilocalorie) 2. Proteins: Sources of proteins: Pulses, egg, fish, chicken, mutton. Animal proteins are called 'first class'  protein. 1 gm protein = 4 Kcal of energy. Proteins are formed by amino acids. Hence on digestion, protei
