Method Quantitative separation of grana-vesicles (a-vesicles) and stroma + end membrane vesicles (ß-vesicles) from spinach chloroplasts. See notes beneath table
Comments Under light limiting conditions, the ratio of the number of turnovers, and hence the ratio of the potential capacity for electron transport, of PSI to that of PSII for the whole thylakoid is ~1.4. In the case of spinach, PSI and PSII capture 59% and 41%, respectively, of the total quanta received by the photosynthetic membrane in daylight.
