Answer:
Mitochondria D; french spell as Mitocodras
Explanation:
Mitochondria are double- membrane bound organelles found in all eukaryotic organisms;Their sizes varies in organism from 0.75 to 3 micrometer in area..
They are most abundant in the muscles cells, liver, and kidney where metabolic activities are higher in the body.
Mitochondria are the site of cellular respiration for production of energy therefore, they are called POWER HOUSE.
The sequence of reaction for the energy production begin in the Cytoplasm as Gycolysis, SPLITTING OF GLUCOSE MOLECULE.in the presence of Oxygen the pyruvate product produced moves into the the matrix of the the mitochondria in a cyclical pathways called Kreb's Cycle as acetyl Co A(IN LINK REACTION) for generation of 2 ATPs per molecule of glucose. This is Substrate level phosphorylation it also involved the generation of reduced Co-enzyme NADH and FADHH2.
However, it is in the process of oxidativephosphorylation( through chemosmosis ) in the matrix of mitochondria that large number of ATPs are produced, this particular reaction made mitochondrial the power generation center of the cell.
38 ATPs are produced.
in tissues hypoxia,(shortage of Oxygen) or presence of oxygen inhibitors,NO energy is produced because no oxygen to initiate kreb cycle and therefore oxidative phosphorylation .
