So, apoptosis or programmed cell death is a natural event that is occur in every cell.
00:09
The pcd, which is known as the programmed cell death, also known as apoptosis, is happening by two different mechanisms, extrinsic and intrinsic.
00:23
So the extrinsic mechanism involves external sources that initiate apoptosis.
00:28
So the extrinsic options are pathogens and carcinogens.
00:37
So carcinogens and pathogens initiate the extrinsic pathway with the help of the death receptors.
00:47
So these death receptors initiate extrinsic pathway and lead to programmed cell death.
00:53
So the intrinsic pathway is activated by internal.
00:59
Processes such as internal mutations or spontaneous mutations that takes place in every organism or every cell.
01:06
So these mutations affect the bcl or b cell lymphoma 2 proteins that is the bcl proteins bcl2 proteins such as back and backs.
01:23
So these proteins are usually found on the we'll draw the diagram is usually found on the mitralia.
