WebDec 13, 2024 · Robert Hill (1937) found that the ‘light phase’ of photosynthesis can operate independently from the ‘dark phase’ (the carbon reaction phase), since isolated chloroplasts can evolve O 2 in the presence of artificial electron acceptors [this reaction is called the ‘Hill-reaction’ in honor of Robert (Robin) Hill], even in the absence ... Webdependent reactions, plants would not have a sufficient supply of these important compounds necessary for metabolism. This experiment focuses on the light reactions of photosynthesis, specifically on the Hill reaction, where, in response to light, an electron acceptor is reduced by electrons from water, and oxygen is evolved.
WebMay 17, 2024 · Hill reaction The release of oxygen from isolated illuminated chloroplasts when suitable electron acceptors (e.g. potassium ferricyanide) are added to the … WebThe meaning of HILL REACTION is the light-dependent transfer of electrons by chloroplasts in photosynthesis that results in the cleavage of water molecules and liberation of …
WebThe minimum quantum requirement for photosynthesis under optimal conditions is about nine. Thus, the energy used is 9 × 50, or 450 kcal per mole of oxygen evolved. Therefore, the estimated maximum energy efficiency of photosynthesis is the energy stored per mole of oxygen evolved, 117 kcal, divided by 450—that is, 117/450, or 26 percent.
