And then the glucose can be used by these, let's say, skeleton muscle cells to basically produce ATP molecules which themselves are used to basically contract the skeleton muscle. And once the skeleton muscle contracts, that is precisely what allows us to basically run away from that animal, from that bear. So carry out that particular type of physiological effect. Now, what about the phosphorosotide cascade? What types of kinases are used in this case? Well, in our discussion we focused on two different types of kinases.
