Statements and determine if they're true or false.
00:02
So i'm not going to write down the statements, but let's just go through these.
00:07
The first one, a phosphorylation cascade relies on protein modifications and phosphorylation.
00:14
Well, that's going to be a true statement, the cascade.
00:17
We look at the modifications, et cetera.
00:19
The second messenger is the same molecule as the ligand, but just found intracellularly.
00:26
No, it wouldn't be the second messenger, so we're going to say that is false.
00:31
The phosphorylation cascade is composed of protein kinesis.
00:35
Well, that's true.
00:35
It is full of protein.
00:37
Let's look at the fourth one.
00:39
Signal transduction is the cell signaling or transmitting the signal from the cell's surface protein to the cell interior to bring about a cell response.
00:50
Yes, that's the whole point.
00:51
We want to have a response, and it's got to transduce.
00:55
So now let's look at the fifth one.
00:56
These statements and determine...
