Pull-down assays using proteins that ONLY bind to the GTP-bound version of the small G-protein can be used to detect when small G proteins like Rac1 have been activated by various growth factors.  You were given two lysates, one having been treated with platelet-derived growth factor (PDGF) and the other not treated with PDGF. This method is similar to performing co-IPs, so based on that knowledge, which of the following steps is erroneous?

Some of the statement is given regarding the Pyruvate kinase 

a. Pyruvate kinase is activated  by ATP, acetyl-CoA, long-chain fatty acids 

b. Pyruvate kinase is allosterically inhibited by ATP, acetyl-CoA, long-chain fatty acids

c. Accumulation of alanine allosterically inhibits pyruvate kinase M in muscles, slowing the production of pyruvate by glycolysis

d. Accumulation of alanine activate pyruvate kinase M in muscles, increases the production of pyruvate by glycolysis
