All Organelles have unique functions and perform specific jobs ,[object Object],[object Object],[object Object],[object Object],[object Object]

Mitochondrion (Chondriosome) ,[object Object],[object Object],[object Object],[object Object],[object Object]

Mitochondrion Matrix Inter Membrane Space Outer Membrane Inner Membrane Folded Inside To Form Cristae

Mitochondrion Energy yielding metabolic processes  Biological Oxidation (Respiratory Chain).  Oxidative Phosphorylation.  Citric Acid Cycle.  Oxidation of Fatty Acids. CO, CN and other deadly Poisons cause Death because they block the energy yielding reactions in Mitochondria.

Mitochondria (Chondriosomes) are Powerhouse of cells ,[object Object],[object Object],[object Object],[object Object]

Mitochondria are site for many other Specific Cellular Activities ,[object Object],[object Object],[object Object]

Mitochondrial Medicine ,[object Object]

Mitochondrial Diseases (Mitochondrial Cytopathies) ,[object Object],[object Object],[object Object]

Depending on which cells of the body are affected, Mitochondrial Diseases may result in: ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Endoplasmic Reticulum is Interconnected Network of branching canals and vesicles

Endoplasmic Reticulum is Interconnected Network of: Tubules Vesicles Sacs (Cisternae)

Two Types Of Endoplasmic Reticulum ,[object Object],[object Object],Ribosomes

Endoplasmic Reticulum is Membrane Bound Organelle Involved in Synthesis of Proteins & other Compounds ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

RER Is the Site for Protein Synthesis ,[object Object],[object Object],[object Object],[object Object],[object Object]

Each cell contains thousands Miniature “Protein Factories” The Ribosomes ,[object Object],[object Object],[object Object],[object Object],[object Object]
