Case-Based-III: This structure is visible under light microscope as small spheres. It is present in all eukaryotic cells which undergo aerobic respiration. It is a double membrane bound organelle. It generates energy in the form of ATP. It has inner folds called cristae which help in increasing the surface area for absorption. They have their own DNA, RNA and ribosome through which they are able to replicate and forms proteins hence known as semi-autonomous organelle.
1. Identify the cell organelle and mention its common name:
a. Plastids; kitchen of the cell
b. Mitochondria; power house of the cell
c. Lysosome; suicidal bags
d. Ribosome; factory of protein
2. Name the components labelled as ( mathrm{X}, mathrm{Y} ) and ( mathrm{Z} ) in the diagram:
a. Crista, mitochondrial matrix and DNA
b. Crista, DNA molecule and mitochondrial matrix
c. DNA, mitochondrial matrix and lumen
d. Mitochondrial matrix, crista and DNA
3. What is the function of the component labelled as X:
a. Site of Kreb’s cycle
b. Site of protein synthesis
c. Duplication of organelle
d. Increases surface area of respiration
4. Which structure of mitochondria act as the site of Kreb’s cycle?
a. ( mathrm{X} )
b. Z
c. ( mathrm{Y} )
d. None of these
d. None of these
