   Jan 2, 2023 · Photosynthesis, measured as 2,6-dichlorophenolindophenol (DCPIP) reduction or ATP production, was found to be enhanced in the conjugated chloroplasts (Bai et al., 2021). Carbon quantum dots are small NPs (diameter < 10 nm) and appear to be capable of entering chloroplasts and converting UV light into photosynthetically active radiation, thereby ...

   Although energy production or consumption can be cell-type specific (Yin & Struik, 2018, 2021), the model of von Caemmerer and Furbank for C 4 photosynthesis assumed that energy is shared between M and BS cells, and used x to allocate J atp to the CCM cycle (see Equation ) and thus, 1 − x to the Calvin–Benson cycle (see Equation ).

   Jul 6, 2020 · In the light, the photosynthetic electron transfer chain consisting of photosystem II (PSII), the cytochrome b 6 f complex (cytb 6 f), photosystem I (PSI), and the free electron carriers plastoquinone (PQ) and plastocyanin, lead to the production of ATP and NADPH that fuel the Calvin-Benson cycle (CBC) and other assimilatory processes (Rochaix ...

   What is a 2021 recovery ATP?

   • The 2021 Recovery ATPs maintains the use of current LTSM and resources already available in the system. Content topics removed in 2020 were not automatically returned in the 2021 Recovery ATPs. Learning losses due to COVID-19 across grades and subjects will vary from school to school, class to class and even within classes.

   Does chloroplast ATP synthase require a Q cycle?

   • The latter combination is very close to the contemporary belief that the operation of the Q cycle is obligatory (Sacksteder et al., 2000) and the structural data that chloroplast ATP synthase requires 4.67 c subunits or protons to produce one ATP (Seelert et al., 2000; Hahn et al., 2018 ).

   Is NADPH required for C4 photosynthesis?

   • Based on this NADPH-determined model, Yin and Struik ( 2012) stated that the photosynthetic quantum yield models for C 4 photosynthesis are the same as for C 3 photosynthesis, that is, Equation ( 12a) or Equation ( 12e ), reflecting that there is no net NADPH requirement for the C 4 cycle (but again, see discussion later).

   Does photosynthesis depend on the rate of regenerated RuBP?

   • Photosynthesis can also depend on the rate at which RuBP is regenerated. This usually occurs at high CO 2 concentration and/or low light. The model assumes RuBP regeneration-limited photosynthesis is controlled by electron transport (Farquhar et al., 1980 ).
