5. Cell Structure And Organization - part 05 - Cytoplasm


Cytoplasm :

  • The cell contains ground substance called cytoplasmic matrix or cytosol.
  • This colloidal jelly like material is not static. 
  • It shows streaming movements called cyclosis. 
  • The cytoplasm contains water as major component along with organic and inorganic molecules like - 
  1. sugars
  2. amino acids
  3. vitamins
  4. enzymes
  5. nucleotides
  6. minerals and 
  7. waste products.


  • It also contains various cell organelles like -  
  1. endoplasmic reticulum
  2. Golgi complex
  3. mitochondria
  4. plastids,
  5. nucleus
  6. microbodies
  7. and cytoskeletal elements like microtubules.


  • Cytoplasm acts as a source of raw materials as well as seat for various metabolic activities taking place in the cell.
  • It helps in distribution and exchange of materials between various cell organelles.
  • Cell organelles are nothing but compartments in the cell that carry out specific functions. 
  • Some of them coordinate with each other and complete specific tasks for the cell.
  • Nuclear membrane, endoplasmic reticulum, Golgi complex, lysosomes and various types of vesicles and vacuoles form such a group and are together considered as endomembrane system of the cell. 
  • Organelles having distinct functions are not included in endomembrane system. 
  • e.g. mitochondria or chloroplast carry out specific type of energy conversions in the cell.

  6. Biomolecules - part 01 - Carbohydrates Introduction : Our planet is having a wide diversity of living organisms that are classified as - unicellular  (consisting of a single cell; including bacteria and yeast) or  multicellular  having many cells (e.g. plants and animals).  living organisms have cell as the basic structural and functional unit.  The cells have protoplasm containing numerous chemical molecules, the biomolecules. Biochemistry  : Biochemistry is  biological chemistry  that provides us the idea of the chemistry of living organisms and molecular basis for changes taking place in plants, animals and microbial cells.  It develops the foundation or understanding  all biological processes  and communication within and between cells as well as chemical basis of inheritance and diseases in animals and plants. Chemical analysis of all living organisms indicates presence of the most common elements like  carbon, h...

  6. Biomolecules - part 02 - Lipids B. Lipids : These are group of substances with greasy consistency with  long hydrocarbon chain containing carbon, hydrogen and oxygen. In lipids, hydrogen to oxygen ratio is  greater than 2:1  (in carbohydrates it is always 2:1). Lipid is a broader term used for fatty acids and their derivatives.  They are soluble in organic solvents (non-polar solvents).  Fatty acids are organic acids which are composed of hydrocarbon chain  ending in carboxyl group (-COOH).  They can be  saturated fatty acids  with no double bonds between the carbon atoms of the hydrocarbon chain.  Palmitic and stearic acids  found in all animal and plant fats are examples of saturated fatty acids. Unsaturated Fatty Acids  are with one or more double bonds between the carbon atoms of the hydrocarbon chain.  Oleic acid  found in nearly all fats and  linoleic acid  found in many seed oils are example...

6. Biomolecules - part 05 - Enzymes

  6. Biomolecules - part 05 - Enzymes Enzymes : Thousands of different chemical reactions take place automatically at a given time in a tiny living cell. The reactions take place at the body temperature.  If these enzymes were not present in the cell, either the reactions would not occur or if they occur they would occur at a  very very slow rate . Know the scientists : German chemist  Edward Buchner  discovered enzymes by accident.  Buchner discovered that living cells were not necessary but that  yeast  extract could bring about fermentation.  He then coined the term Enzyme (Gk. En = in, zyma = yeast i.e. in yeast). This term is now commonly used for all biocatalysts. Each enzyme catalyzes a small number of reactions, specifically perhaps only one. Substrate :  The substance upon which an enzyme acts is termed as the substrate.  Endo-enzymes :  The enzymes which act within the cell in which they are synthesizedare known as en...
