The cell demands to know that a stimulus to grow comes from the receptor. It does that by requiring that multiple factors or pathways are activated. Which is NOT a component of this system?
A. Activation of the Ras pathway leads to apoptosis
B. Activation of PI-3 kinase leads to activation of Akt (PKB)
C. Activation of the Ras pathway leads to assembly of AP-1
D. Release of Nitric oxide leads to elevation of cGMP

Drosopholia eye development is an example of cell differentiation directed by signal binding to a receptor tyrosine kinase (RTK). In this pathway, R7 photoreceptor development requires a receptor (SEV, sevenless), which is activated by binding to a plasma membrane bound signal (BOSS, bride-of-sevenless) displayed on the adjacent R8 cell Receptor activation leads to activation of RAS via two proteins, Drk (down- stream of receptor kinases) and Sos (son-of-sevenless). Activated RAS leads to activation of a phosphorylation cascade that activates the...
1. According to the paper, what does lactate dehydrogenase (LDH) do and what does it allow to happen within the myofiber? (5 points) 2. According to the paper, what is the major disadvantage of relying on glycolysis during high-intensity exercise? (5 points) 3. Using Figure 1 in the paper, briefly describe the different sources of ATP production at 50% versus 90% AND explain whether you believe this depiction of ATP production applies to a Type IIX myofiber in a human....
