Mitochondria

Name : Mitochondrion ( plural - mitochondria), power house of the cell.


Properties : 
  • It is membrane bounded cytoplasmic organelle.
  • It's shape rod or oval, and diameter 0.5 - 1.0 micrometer.
  • It covered bilayered membrane 
    • Outer membrane : is smooth and encloses the contents of mitochondrion as well various enzymes such as acetyl-CoA synthetase, glycerophosphate, acetyltranferase.
    • Inner membrane : is folded in the form of shelf-like inward projection called cristae (crista). Cristae contain many enzymes and other protein molecules which helps in functioning. (Functions + enzymes + protein molecules in cristae = respiratory chain or electron transport chain). Enzymes of respiratory chains are 4-8 in list below.  
  • It's DNA contain 37 gene.
  • It responsible for maternal child relation.
  • It contains many enzymes and protein.
  • Increase no of mitochondria by the exercise.
  • It is the site of aerobic respiration



Enzymes and protein : 
  1. Acetyl CoA synthesase.
  2. Glycerol phosphate.
  3. Acetyl transferase.
  4. Succinic dehydrogenase .
  5. Dihydronicotinamide adenine dinucleotide dehydrogenase .
  6. Cytochrome oxidase.
  7. Cytochrome -C
  8. ATP synthase.
Functions : 
  1. Self replication .
  2. Production of cellular energy and synthesis of ATP (that's by known as "power house" of the cell).
  3. Apoptosis 
  4. Storage of calcium
  5. Detoxification of ammonia in liver

Lysosomes

Name :- Lysosomes, garbage system of the cell, suicidal bag of the cell Properties : These are membrane bound vesicular structures founds throughout the cytoplasm. These are formed by the process of packaging in the golgi apparatus. Enzymes of lysosomes are synthesized in rough endoplasmic reticulum. Among the organelles, the lysosomes have the thickest covering membrane that is formed by a bilayered lipid material . Lysosomes have 50 different hydrolytic enzymes, known as acid hydroxylases. Types of Lysosomes : Primary lysosomes, this is an inactive of form of lysosomes. Secondary lysosomes, this is an active form of lysosomes (lysosomes active during phagosome or endosome and at this time lysosomes pH become acidic and enzymes are activate). Lysosomal Enzymes :   Proteases :- which hydrolyze the proteins into amino acids. Lipases :- which hydrolyze the lipids into fatty acids and glycerides. Amylases :- which hydrolyze the polysaccharides into glucose. Nucleases :- whi
