(20) Flash photolysis kinetics of carbon monoxide hemoglobin show a decrease in the fraction of ligand recombination occurring as geminate when the hemoglobin has fewer ligands bound.
Germinate
Definition:
(v. i.) To sprout; to bud; to shoot; to begin to vegetate, as a plant or its seed; to begin to develop, as a germ.
(v. t.) To cause to sprout.
Example Sentences:
(1) In contrast, in primordial follicles, FSH was restricted to the germ cell but was present in both the oocyte cytoplasm and germinal vesicle.
(2) T cells admixed in the germinal centers were overwhelmingly of the T-helper type.
(3) The lack of TBM prior to germinal center development and their absence in aged mice are inconsistent with the concept that TBM are required for the induction of the germinal center reaction.
(4) In contrast, Sca-2 did not appear to stain peripheral T lymphocytes, but recognized only a subset of B lymphocytes which could be localized by immunohistochemistry to germinal centers.
(5) The processes of germination and gruel preparation of germinated materials contributed to the digestibility of weaning foods prepared from cereals and legumes.
(6) The results presented here substantiate the hypothesis that in S. cerevisiae trehalose supplies energy during dormancy of the spores and not during the germination process.
