Abstract

The amino acid derivatives of 1,4-naphthoquinone (aspartic acid) in the concentrations of 10-5- 10-7M leads to decreasing activity of membrane Na+, K+-ATPase embryos of loach (Misgurnus fossilis L.) at different stages of blastomer division. At stage 10 division of blastomers the 2-asparagine-3-chloro-1,4-naphthoquinone in the concentration 10-10M leads to increasing the activity of Na+, K+-ATPase. It causes changes in dynamics of transmembrane potential (TMP) in division of blastomer. It causes reduction of amplitude and absolute values of TMP.
