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
