This question is asking about hormones, and it gives us five statements here, and we're supposed to determine which one is true for all hormones.
00:13
So let's just take each statement one by one.
00:16
So our first statement is about where the hormones come from, where they're secreted from.
00:24
So most hormones come from glands are secreted by glands in the body, but not all of them.
00:33
So not all hormones are from glands.
00:43
For example, some come from these isolated endocrine cells, for example, within the walls of the intestine, that can secrete a hormone.
00:54
So most, but not all.
00:56
So that's not our answer.
00:58
Our second statement has to do with receptors.
01:01
So many cells have receptors on the outside that hormones, especially those, that are proteins, for example, will bind to.
01:12
But there are some hormones that can pass through the membrane and access receptors inside the cell.
01:23
So some receptors are inside the cell.
01:33
Okay, so that is not true for all hormones either.
01:37
Our third has to do with the response of hormones.
01:41
So the response a cell has from a hormone is based on what kind of cell that is and the receptors that it has...
