  2. Fractionation of carbon isotopes in oxygenic photosynthesis

    en.wikipedia.org/wiki/Fractionation_of_carbon...

    The overall equation for the light-dependent reactions is generally: [11] Overview of the Calvin cycle and carbon fixation C3 Pathway. 2 H 2 O + 2 NADP + + 3 ADP + 3 P i + light → 2 NADPH + 2 H + + 3 ATP + O 2. The light-independent reactions undergo the Calvin-Benson cycle, in which the energy from NADPH and ATP is used to convert carbon ...

    A diagram of the Hill reaction which shows with the usage of an artificial electron acceptor such as DCPIP, and the chloroplast is subjected to light there is a release of oxygen, Also with the absence of CO 2 there is no sugar production A diagram of the Hill reaction taking place under dark conditions there is no oxygen emitted and the no ...

  4. Light-dependent reactions - Wikipedia

    en.wikipedia.org/wiki/Light-dependent_reactions

    Light-dependent reactions of photosynthesis at the thylakoid membrane. Light-dependent reactions are certain photochemical reactions involved in photosynthesis, the main process by which plants acquire energy. There are two light dependent reactions: the first occurs at photosystem II (PSII) and the second occurs at photosystem I (PSI).

  5. Photodissociation - Wikipedia

    en.wikipedia.org/wiki/Photodissociation

    Photodissociation, photolysis, photodecomposition, or photofragmentation is a chemical reaction in which molecules of a chemical compound are broken down by absorption of light or photons. It is defined as the interaction of one or more photons with one target molecule that dissociates into two fragments.

  6. Photosystem I - Wikipedia

    en.wikipedia.org/wiki/Photosystem_I

    Photosystem I (PSI, or plastocyanin–ferredoxin oxidoreductase) is one of two photosystems in the photosynthetic light reactions of algae, plants, and cyanobacteria. Photosystem I [1] is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from plastocyanin to ferredoxin.

    The Office of Inspector General (OIG) in the U.S. Agency for International Development (USAID) is responsible for detecting and preventing fraud, waste, abuse, and violations of law and to promote economy, efficiency and effectiveness in the operations of USAID, the Millennium Challenge Corporation, the United States African Development Foundation, and the Inter-American Foundation.

  8. Light curve (botany) - Wikipedia

    en.wikipedia.org/wiki/Light_curve_(botany)

    In botany, a light curve shows the photosynthetic response of leaf tissue or algal communities to varying light intensities. The shape of the curve illustrates the principle of limiting factors; in low light levels, the rate of photosynthesis is limited by the concentration of chlorophyll and the efficiency of the light-dependent reactions, but in higher light levels it is limited by the ...

    The CIA OIG investigation of the Iran Contra scandal was criticized in the final report of the Congressional investigation of the Iran-Contra affair. [3] Members of the Senate Select Committee on Intelligence (especially Boren, Cohen, Specter, and Glenn) wrestled with how to improve the IG while not interfering with the work of the CIA.
