00:07
Okay, so for this question, we're going to go through the letters, and then we're going to look at the matching solution.
00:15
So we're mainly looking at organelles and items inside the cell here.
00:18
So a is the endoplasmic reticulum.
00:24
So that is going to be number nine, which is a common form of cytoplasmic membrane.
00:40
And that's just because that's a membrane sitting in the cytoplasm, so that makes sense.
00:46
Is going to be the smooth endoplasmic reticulum.
00:50
So smooth er.
00:53
And that is most likely going to fit with 12, which is processing exogenous chemicals.
00:59
And that's because the smooth er is responsible for breaking down toxins.
01:04
Toxins.
01:05
So that's going to be roughly equivalent to processing exogenous chemicals.
01:12
So exogenous chemicals are chemicals outside, coming from outside the cell.
01:19
And the smooth endoplexmer tickam is also involved in lipid synthesis, but that isn't relevant for this question.
01:24
Then the rough er, so let's see, rough er, and that's going to be five.
01:34
So that's going to be the membrane with ribosomes attached.
01:41
And then recall that ribosomes are used to synthesize protein.
01:44
So when we're packaging the proteins in the rough er, it makes sense that they're going to be attached.
01:48
And that's why we see those little dots that are attached to the rough er when we look at models of the cell.
01:57
Okay, moving on to d, the golgi complex.
02:02
So the golgi complex is going to be the site of carbohydrate addition to protein.
02:07
So we're packaging those proteins after they come out of the rough er.
02:11
So that's going to be number 10 adding carbs to protein.
02:19
And that's going to do a multitude of things inside of the cell for a signal.
02:23
Milling and also the function of the proteins that are being produced.
02:28
Okay, moving on to transport vesicles.
02:33
So transport vesicles.
02:37
So that is going to be community number 11, which is allowing communication between the golgi and the rough endoplasmic reticulum.
02:47
So communication between golgi and rough er.
02:52
And that's simply just how.
02:55
They're transported between these two organelles okay i'm having trouble scrolling here um just do one more and then i'll erase these okay so d or sorry uh not d f he's going to be the secretory granules and that is going to be eight they're destined for fusion with the plasma membrane fusion plasma membrane.
03:32
And that makes sense because we're going to be secreting something from the cells.
03:35
So we're going to want to go to the plasma membrane, which separates the inside and outside the cell.
03:41
So we're going to have those secretory granules fuse and allow whatever is in them to leave the cell.
03:48
Okay.
03:49
I'm going to erase these now.
03:54
And then we'll move on to g, which is the endosome.
04:01
Once i get this all erased.
04:06
Okay.
04:08
So g, the endosome and that the endosome is going to match up with four, which is carrying important biochemicals into the cell.
04:22
So carry important biochems into the cell.
04:31
And that makes sense because the endosome is responsible for endocytosis, the opposite of exocytosis...
