Which of these are functions of apoptosis? the elimination of unneeded cells in development, allowing the cells to die in a controlled manner, dividing cells into two identical daughters, or destruction of abnormal cells.
00:15
So there are three answers here, a, b and the d, c is not an answer, c is referring to mitosis, not apoptosis.
00:24
So apoptosis is controlled cell death.
00:28
When the cell dies, there are two main ways it can...
00:32
There's necrosis and is apoptosis.
00:35
Necrosis is uncontrolled.
00:37
The cell is killed and the cell lies it.
00:40
So the membrane bursts and it spills the insides into the extracellular area.
00:46
This leads to inflammation and it has to be cleaned up.
00:49
So if we want a cell to die, we don't want it to be breaking apart.
00:54
We use apoptosis.
00:55
So this is a careful, sequence of events and it involves lysosomes from, so it involves the enzymes from lysosomes, they release their enzymes, and they digest the cell.
01:13
And lebing...
