Carrier-mediated Uptake of Arginine and Urea by Volvox carteri f. nagariensis.
Volvox carteri f. nagariensis takes up arginine via a high affinity, highly specific carrier, whereas carriers for neutral and acidic amino acids cannot be detected (even in nitrogen-starved cultures). Exogenous arginine is accumulated against a steep concentration gradient and is incorporated into protein with high efficiency, but it is not catabolized to any significant extent and will not se...

متن کاملCarrier-mediated Uptake of Arginine and Urea by Chlamydomonas reinhardtii.
Chlamydomonas reinhardtii possesses a high affinity, highly specific carrier involved in uptake of exogenous arginine. Carrier-mediated uptake of other amino acids cannot be detected, even in cultures maintained on amino acids as a nitrogen source or starved for nitrogen. This fact may contribute to the difficulty of isolating strains auxotrophic for amino acids other than arginine; conventiona...
متن کاملSexual Induction in Volvox Carteri
The study of the dependence of reactions on the concentration of various compounds is often of great value in determining reaction mechanisms . In chemical kinetics, it is often found that, according to van't Hoff's rule, the order of dependence of a reaction on the concentration of some compound involved in that reaction is equal to the number of molecules of the compound involved in each reac...
متن کاملA Preliminary Genetic Investigation of VOLVOX CARTERI.
A preliminary genetic analysis of a number of genetic variants of Volvox carteri f. nagariensis is presented. Techniques are outlined for mutagenesis of Volvox, isolation of mutants and routine genetic analysis. All of the mutants show simple Mendelian segregation patterns and have been tentatively placed in 14 linkage groups.
