Rao who was conferred the Bharat Ratna ( ) is also working on similar technology of artificial photosynthesis to produce - Hydrogen fuel (renewable energy). .
Mitochondria Mitochondria are filamentous or granular cytoplasmic organelles present in cells. The mitochondria were first discovered by Kolliker in as granular structures in striated muscles. Mitochondria (singular: mitochondrion) are organelles within eukaryotic cells that produce adenosine triphosphate (ATP) which form the energy currency of the cell, for this reason, the mitochondria is referred to as the “ Power house of the cell ”. Mitochondria vary in size from .
µm to . µm. Mitochondria contain - % protein, - % lipids, - % RNA and small amount of DNA and minerals. .
. Structure of Mitochondria Mitochondrial Membranes: It consists two membranes called inner and outer membrane. Each membrane is - A˚ thick. Outer mitochondrial membrane is smooth and freely permeable to most small molecules.
It contains enzymes, proteins and lipids. It has porin molecules (proteins) which form channels for passage of molecules through it. Figure . Structure of Mitochondria Oxysome Inner mitochondrial membrane is semi permeable membrane and regulates the passage of materials into and out of the mitochondria.
It is rich in enzymes and carrier proteins. It consists of % proteins and lipids. Plant Anatomy and Plant Physiology Cristae: The inner mitochondrial membrane gives rise to finger like projections called cristae. These cristae increase the inner surface area (fold in inner membrane) of the mitochondria to hold variety of enzymes.
Oxysomes: The inner mitochondrial membrane bear minute regularly spaced tennis racket shaped particles known as oxysomes (F particle). They involve in ATP synthesis. F Head Stalk Base F Figure . Structure of Oxysomes Mitochondrial matrix - It is a complex mixture of proteins and lipids.
Matrix contains enzymes for Krebs cycle, mitochondrial ribosomes( S), tRNAs and mitochondrial DNA. . . Functions of Mitochondria Mitochondria is the main organelle of
