Aim of study (acc. to author)

The in vitro activity of three different enzymes from different organisms were measured during exposure to 2450 MHz microwaves.

Background/further details

Enzymes studied were: a) adenylate kinase from rat liver mitochondria and rabbit muscle, b) glucose 6-phosphat dehydrogenase from human red blood cells (erythrocytes) and yeast, and c) membrane bound NADPH cytochrome c reductase from rat liver microsomes.
