15 صفحه اولInhibitors of photophosphorylation and photoreduction.
Thle processes of eniergy transformation in mitochonidria and in chloroplasts have much in common, even though the energy obtained in mitochondria is derived from the oxidation of organic substrates, whereas energy is obtained from light in chloroplasts. A filnal product of both these transformations is ATP. The formationi of ATP is achieved with the participation of cytochromes and probably qu...
متن کاملThe site of ferricyanide photoreduction in the lamellae of isolated spinach chloroplasts: a cytochemical study.
Ferricyanide was used as a Hill oxidant to localize the site of photoreduction in chloroplast lamellae. The ferrocyanide formed on illumination was complexed with copper ions to form insoluble, electron-dense precipitates of Cu ferrocyanide, which can be easily seen in unstained preparations in the electron microscope. Control experiments showed no precipitates in the dark, at zero time, in the...
متن کاملPhotophosphorylation by digitonin-fragmented spinach chloroplasts.
Digitonin has been used successfully to disrupt particulate structures such as mitochondria without loss of their capacity for causing oxidative phosphorylation (1, 2). The present report describes a procedure whereby spinach chloroplasts were extensively disrupted by digitonin extraction to give a preparation of small fragments which could cause an appreciable rate of photophosphorylation. In ...

بر اساس فرضیه شناخت رابینسون (2001 و 2003 و 2005) و مدل ظرفیت توجه محدود اسکهان (1998)، این تحقیق تاثیر پیچیدگی تکلیف را بر پیچیدگی واژگان و صحت گرامری نوشتار مباحثه ای 60 نفر از دانشجویان زبان انگلیسی بررسی کرد. میزان پیچیدگی تکلیف از طریق فاکتورهای پراکندگی-منابع تعیین شد. همه ی شرکت کنندگان به صورت نیمه تصادفی به یکی از سه گروه: (1) گروه موضوع، (2) گروه موضوع + اندیشه و (3) گروه موضوع + اندی...
