Explain why an increase in glycogen phosphorylase activity might result in an increase in pyruvate production in the cell.

Explanation:

In muscle, glycogen phosphorylase is activated by hormones and neural signals such as epinephrine, that stimulate phosphorylase kinase which phosphorylates the Ser-14 residue of the protein. ... The activated kinase in turn activates the glycogen phosphorylase enzyme by phosphorylating the Ser-14 residue.

Plasma cells, they are also called  plasma B cells,  or effector B cells, are white blood cells that secrete large volumes of antibodies. They are transported by the blood plasma and the lymphatic system. Plasma cells originate in the bone marrow; B cells differentiate into plasma cells that produce antibody molecules closely modeled after the receptors of the precursor B cell. Once released into the blood and lymph,
