WebThe pH of various chloroplast compartments, such as the thylakoid lumen and stroma, is light-dependent. Light illumination induces electron transfer in the photosynthetic apparatus, coupled with proton translocation across the thylakoid membranes, resulting in acidification and alkalization of the thylakoid lumen and stroma, respectively. Luminal acidification is … WebJan 12, 2024 · In higher plants, chloroplasts are essential semi-autonomous organelles with complex compartments. As part of these sub-organellar compartments, the sheet-like thylakoid membranes contain abundant light-absorbing chlorophylls bound to the light-harvesting proteins and to some of the reaction center proteins. About half of the …

WebOct 31, 2024 · Chlorophyll Definition. In the year 1817, Joseph Caventou and Pierre Joseph gave the word Chlorophyll, which is present in plants and is responsible for the photosynthesis to take place and is green in color. Thus, chlorophyll can be divided into two parts where chloros means color and phyll means leaf. In the chloroplast is the … WebApr 12, 2024 · Unlike other cell membranes, the nuclear envelope has no pores. 2. Light-dependent reactions take place in the chloroplast stroma. 3.

WebJun 25, 2004 · The chemiosmotic theory of energy transduction across the chloroplast thylakoid membrane postulated that a pH gradient between the stroma and the thylakoid lumen, developed under illumination, drives ATP synthesis ().Subsequently, Jagendorf and Uribe showed that chloroplast thylakoid vesicles synthesized ATP in the dark when … WebJun 25, 2015 · Caplan et al. show that dynamic tubular projections from chloroplasts called stromules are induced during a plant immune response. Stromules form connections with the nucleus and may aid in the transport of pro-defense signals. ... To move from the chloroplast stroma, H 2 O 2 must move across the inner chloroplast membrane, ...
