Abstract

Cirillo, Vincent P. (Seton Hall College of Medicine and Dentistry, Jersey City, N.J.). Mechanism of arabinose transport in Tetrahymena pyriformis . J. Bacteriol. 84: 754–758. 1962.—The mechanism of sugar transport was studied in Tetrahymena pyriformis , using the nonmetabolizable sugar, l -arabinose. Arabinose transport does not result in accumulation against a concentration difference but shows a high Q 10 and is competitively inhibited by glucose. The addition of glucose to arabinose-equilibrated cells results in arabinose efflux against a concentration difference. These results are discussed in terms of carrier-mediated transport.
