Which is NOT true of RTK activation
A. A dominant-negative mutation of the receptor showed that autophosphorylation was possible
B. Whole antibody showed that crosslinking receptors was able to activate them
C. Fab fragments showed that binding alone was not what activated receptors
D. Activation of the receptor is accomplished when tyrosines on the tail of the receptor are phosphorylated

Which is NOT true of RTK activation A. A dominant-negative mutation of the receptor showed that...
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....
