Hemoglobin is a protein that you had found in your red blood cells.
00:04
And so for this question, we would figure out which statement about it is true.
00:10
So first of all, it describes something that has a biconcaved disc shape.
00:16
That is actually talking about red blood cells, which are the official term for red blood cells are rithracites.
00:25
And so hemoglobin is inside of red blood cells but doesn't actually have that biconcone.
00:30
Cave disc shape.
00:32
So that's not the right answer.
00:34
And then glyco protein units.
00:41
Glycoproteins are proteins that have carbohydrates attached to them.
00:49
So let me just write that.
00:53
And so hemoglobin is a protein, not a glycoprotein, and therefore that's incorrect.
01:02
All right.
01:02
So moving right along here.
01:04
One more incorrect answer we need to figure out.
01:09
So let's just talk about what hemoglobin is to figure out this last answer.
01:14
Hemoglobin, we get a different color here.
01:17
Yeah, we'll do black...
