Growth factors such as (e.g., VEGF, platelet-derived growth factor [PDGF] bind to a receptor tyrosine kinase (RTK) on the cell membrane, causing autophosphorylation of the receptor, thus creating docking sites for intracellular signaling proteins
Any muscle loss post-cessation is due to reduced training stimulus or inadequate protein intake, not peptide withdrawal
Similarly, nitrogen fixation by legumes forms NH 4 + inside the nodule, and excessive uptake of K + causes charge imbalance, both of which leads to proton release by the roots to balance the charge (Marschner, 2011), resulting in rhizosphere pH decline
