Sanjay Kashyap 6 years, 8 months ago

Both VBT are CFT perfectly explained in NCERT. Well, i can explain cft in brief right now but vbt is a much lengthy topic. All the orbitals in subshell have different orientations. Whenever there is repulsion between the ligand field and any of the orbitals, the orbitals acquire higher energy. The repulsion arises when an orbital is oriented towards the ligand field. In octahedral complexes, two d orbitals acquire higher energy while in tetrahedral comolexes, three d orbitals acquire higher energy

The mitochondria is also called powerhouse of the cell.
It is surrounded by two membranes.
The outer membrane is porous wherea the inner membrane has deep folds that provides a large surface to perform the chemical reactions required for the generation of ATP.
The inner membrane is compartmentalized into various cristae.
The ground substance or space enclosed by inner membrane is called matrix.
Mitochondria have their own DNA and ribosomes and are hence capable to produce some of their required proteins all by themselves.
