[Photophosphorylation, sensitized by chlorophills a and b, pheophytin and beta-carotene in a modelled system].

In aqueous solutions in air atmosphere chlorophylls a and b, pheophytin and beta-carotene adsorbed on aluminium oxide powder are capable of sensibilizing electron transfer from phosphate ions coupled with the formation of high energy bonds of adenosine phosphates. The highest activity of chlorophylls a and b and pheophytin is observed within the pH range of 7.5-7.8; that of beta-carotene--at pH 7.3-7.5.
