Effect of cold adaptation on total enzyme activities of L cells

Using cytochemical methods, the authors tested enzymatic reactions in L-As and L-C3 cells. They found that esterase activity in particular, but also several other enzyme activities, were higher in L-C3 cells than in L-As cells. This furnished further evidence of the raised metabolic activity of the cold-resistant cell subline L-C3 compared with the L-As line.
