In a branched phosphorylation network, kinase A activates both kinase B and kinase C simultaneously. Kinase B provides 8-fold amplification to target protein X, while kinase C provides 12-fold amplification to target protein Y. If kinase A activity increases 3-fold, what is the combined increase in total phosphorylated target proteins (X + Y)?
