Abstract
    1. 1. Hexokinase from the mantle tissue of M. Edulis was investigated over almost 2 years for changes in specific activity and in the kinetic characteristics of the glucose concentration vs initial velocity curves.2. 2. Specific activity changed markedly, peaking in late Spring.3. 3. Depending upon the time of the year and the sex of the mussel, the substrates versus velocity data were best fitted either to a Michaelis-Menten or a Hill model. The apparent Km or K0.5S values changed seasonally, being low during the first part of the year and high for most of the rest of the year.4. 4. The changes in hexokinase are discussed in relation to the two possible seasonally-variable sources of glucose production, food intake and the utilization of stored
