effect of oral presentation on development of l2 learners grammar
this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
15 صفحه اولMitochondrial trans-2-enoyl-CoA reductase of wax ester fermentation from Euglena gracilis defines a new family of enzymes involved in lipid synthesis.
Under anaerobiosis, Euglena gracilis mitochondria perform a malonyl-CoA independent synthesis of fatty acids leading to accumulation of wax esters, which serve as the sink for electrons stemming from glycolytic ATP synthesis and pyruvate oxidation. An important enzyme of this unusual pathway is trans-2-enoyl-CoA reductase (EC 1.3.1.44), which catalyzes reduction of enoyl-CoA to acyl-CoA. Trans-...
متن کاملAvian Thiamin Deficiency
A correlation of the histopathology and clinical behavior of thiamin deficient pigeons has been undertaken. Opisthotonus in acutely deficient pigeons was frequently attended by no degenerating nerve fibers or neurons in either the central or peripheral nervous systems. When the deficiency was complicated by starvation, it developed more slowly, opisthotonus appeared later, and many degenerating...
متن کاملVariability of wax ester fermentation in natural and bleached Euglena gracilis Strains in response to oxygen and the elongase inhibitor flufenacet.
Euglena gracilis is able to synthesize adenosine triphosphate under anaerobic conditions through a malonyl-independent fatty acid synthesis leading to wax ester fermentation. Mitochondrial fatty acid synthesis uses acetyl-CoA and propionyl-CoA as C2- and C3-donors for de novo synthesis of even- and odd-numbered fatty acids, respectively. Euglena's wax ester fermentation has only been described ...
متن کاملCritical Involvement of Environmental Carbon Dioxide Fixation to Drive Wax Ester Fermentation in Euglena
Accumulation profiles of wax esters in Euglena gracilis Z were studied under several environmental conditions. The highest amount of total wax esters accumulated under hypoxia in the dark, and C28 (myristyl-myristate, C14:0-C14:0) was prevalent among all conditions investigated. The wax ester production was almost completely suppressed under anoxia in the light, and supplying exogenous inorgani...
