ACTION OF IONIZING RADIATIONS ON CELL CONSTITUENTS 



Inhibition of protein synthesis or of incorporation of amino acids into 

 proteins does not appear to be of crucial importance either : many instances 

 where these are not immediately affected have been described as can be 



Table II. Effects of ionizing radiations on lipid and protein metabolism 



seen from Table II. Synthesis of adaptive enzymes has been inhibited only 

 in a few cases by X-rays, although such an affect is usual with ultraviolet 

 rays. Synthesis of adaptive enzymes is probably related to the presence of
