WebNov 25, 2024 · The protein kinase enzyme family plays a pivotal role in almost every aspect of cellular function, including cellular metabolism, division, proliferation, transcription, movement, and survival. Protein kinase A (PKA), whose activation is triggered by cyclic adenosine monophosphate (cAMP), is widely distributed in various systems and tissues … WebThe value of the equilibrium constant is given by. Kb = [BH+][OH−] B. The greater the value of Kb, the stronger the base. For most weak acids, Kb ranges from 10−2 to 10−13. pKb = − logKb. For most weak acids, pKa ranges from 2 to 13. The smaller the value of pKb , the stronger the base. Here's a video on pKa and pKb.

These values indicate that the products of a strong acid reaction are heavily favored compared to the reactants. So very large numbers for Ka and negative values for pKa for strong acids.
WebAug 18, 1998 · The phosphorylation of PKA by PDK1 is rapid and is insensitive to PKI, the highly specific heat-stable protein kinase inhibitor. A mutant form of the catalytic subunit where Thr-197 was replaced with Asp was not a substrate for PDK1. WebThis equation can be rearranged as follows. This shows how pKa and pH are equal when exactly half of the acid has dissociated ( [A - ]/ [AH] = 1). If the pH changes by 1 near the pKa value, the dissociation status of the acid changes by an extremely large amount. In the case of acetic acid, for example, if the solution's pH changes near 4.8, it ...
