Hi everyone. Here's our next question. What is the important tense of the networks formed by many signal transaction pathways? Well, let's think about the phrase network as opposed to a linear arrangement. When we think of signal transaction pathways. So it's not just signal signal signal but a whole network of these pathways. That means there's many chances for these pathways to intersect and overlap with each other. And what would be the benefit of having a system like that? Well, the answer is that then when we have different signals coming information can be integrated from all these different signals at once and that's going to be more efficient, then responding two individual signals. So instead of having to just have signal response, signal response signal response, all separated signals can come in be integrated together and that will give a more efficient response. So when we look at choice A it does say it can lead to an efficient interpretation and response of signals. So Choice A Here is the correct answer. What is the importance of the network formed by signal transaction pathways? It can lead to an efficient interpretation and response. See you in the next video

What does it mean to say that a signal is transduced? a. The signaling molecule enters the cell directly and elicits a cellular response. b. The signal is generated by the production of proteins. c. The physical form of the signal changes between the outside of the cell and the inside. d. The signal is amplified.

Suppose you were to model amplification by the phosphorylation cascade in Figure 11.16, using a penny for each kinase 1, a nickel for each kinase 2, and a dime for each kinase 3. Also suppose that Ras and each of the kinases can activate 10 proteins. How much money would you need to construct your model?
