Not yet to answer this question, i talk about metabolism.
00:03
It says, you have many blanks here to complete, okay? so i just want to read and complete these blanks here.
00:09
It says, it is important that cells maintain, and we have here, by this winning, they must maintain the ph, the correct amount of small and large molecules, the correct temperature, etc.
00:21
So practically, it is talking about a stable internal medium.
00:25
So it is called homeostasis.
00:29
So you have here homeostasis.
00:31
Then he says, to do this requires work.
00:37
The three types of cellular work are, and here you have transport work.
00:42
I'm going to write that here, okay? transport work, you also have chemical work, and also mechanical work.
00:56
So these are the three types of cellular work.
00:59
Then he says, for example, cells must transport ions such as sodium and hydrogen ions across cell membranes.
01:05
To do work requires energy.
01:09
Metabolism is the assume of all the chemical reactions taking place in your cell.
01:15
Here you have blank refers to reactions that build molecules and required energy, whereas blank is the reactions that break down molecules to release energy.
01:23
So in this case you have anabolism.
01:28
Anabolism, and here you have catabolism that is the inverse process of anabolism...
