Video transcript

Hello everyone and welcome to today's video stating what effect will low lutin izing hormones have on the signal transaction cascade in the testes. So there's two main hormones that we need to understand relating men under structural reproductive organs. In this case, the first one that we're going to talk about is going to be FSH is follicle stimulating hormone and in men, FSH holds with sperm production and development. So low FSH is going to yield a low sperm count or low sperm production in men. However, we also have LH or euthanizing hormone, which is what the problem is about. And this scrutinizing hormone helps with testosterone production. If we have a low liberalizing hormone, then we're going to have low testosterone production. So let's use this information in order to solve the problem and looking at our answer choices. The only answer choice that relates to this decrease in the testosterone production is going to be answer choice A which states it will result in testosterone production failure. So it's going to be the final answer to our question. I really hope this video helped you

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?

Suppose you have an antibody that binds to the receptor tyrosine kinase illustrated in Figure 11.16. When you add this antibody to the cell, you find that it activates the cell response, even when no signaling molecule is present. Explain this result.
