MITOCHONDRIA Flashcards
Who first observe the mitochondria and where ?
It was first seen by Kolliker in the flight muscle of the insect.
Who called mitochondria “bioplast” ?
ALTMANN
Who gave the term mitochondria ?
BENDA
What is the shape and size of the mitochondria ?
SHAPE - Round , oval , sausage and cylindrical shape
SIZE - length = 1 - 5 um
- width = 0.1 - 1 um
What is the number of mitochondria in
a) Micro Steria (an algae)
b) Chaos - chaos (giant amoeba)
c) Flight muscle of insect
a) 1 mit./cell
b) 50,000 mit./cell
c) 5,00,000 mit./cell
Which dye is used to stain mitochondria ?
JANUS GREEN-B Dye
What is all mitochondria present in the cell known as ?
CHONDRIOMES
LEARN THE DIAGRAM OF THE MITOCHONDRIA FROM THE NOTES
DONE :D
Explain about the inner membrane of the mitochondria ?
- Smooth
- Lipid - 40% and proteins - 60%
- Enzyme association and expansion is less.
- More permeable due to porins
Explain about the outer membrane of the mitochondria ?
- Infoldings
- Lipid - 20% and proteins - 80%
- Enzyme association and expansion is more.
- Selectively permeable
What are the marker enzyme of the mitochnodria ?
SUCCINATE DEHYDROGENASE
What are oxysomes ?
The inner membrane or cristae is studied with numerous knob like structure called OXYSOMES

What is the function of the mitochondria ?
- Site for aerobic respiration
2. It is is a miniature body in which the food stuff gets oxidized.
Why do cytoplasmic male sterility in maize occur ?
Due to MITOCHONDRIAL IMBALANCE
