Chemical and Biochemical Equations

One of the key energy-transfer reactions inside the cells of all living things is described as 

The standard chemical equihbrium constant (Chapter 12) for reaction 16.N would be 

Biochemists define a apparent equilibrium constant, K for biochemical reactions as (for Equation 16.P) 

To maintam parallelism with Chapter 12, they define 

The equilibrium constants in common biochemical use have the following symbols, K, Ar , and Kc with concentrations expressed in mol fraction, molaUty and molarity [15]. One also sees representing concentrations shown as activities, such as the AT in Chapter 12.
