Okay, in order to answer this question, let's talk about the cell size and metabolism, practically.
00:05
Okay, remember that metabolism are all those chemical reactions that are going to make the cell function.
00:19
Okay, and practically, practically they are going to maintain the living state of the cell.
00:24
Okay, this is what metabolism is.
00:27
And also we have cell and it has it is surrounded by a cell membrane.
00:33
Okay, and this cell has to have a specific size in order to work perfectly.
00:41
Remember that this cell is going to move substances across a cell membrane.
00:46
Substances are going to move in and out or out and in.
00:49
According to gradients, also there are going to be different types of transport, like passive transport, like it transport, and this is going to allow an appropriate omniostasis, because, for example, sodium ions can get inside or glucose.
01:03
Molecules can get inside in order to produce atp, many other types of cell transfer that occur in the cell memory.
01:12
So because of this, the cell size is very, very, very important.
01:17
Why? because the larger the cells are, the more difficult, more difficult is for nutrients and also gases to move in or out.
01:34
Okay.
01:36
And and and why? well, because as cell grows, as a cell grows, the volume is going to increase more quickly than its surface area.
01:47
So practically, if a cell was to get very large, like in this case, the small surface area that has been distributed along all the cell membrane, would not allow enough nutrients to enter the cell quickly, enough for the cells needs.
02:06
Okay, so this is practically the importance of the size or the appropriate size for the cell...
