Photochemical phase of photosynthesis
WebFigure 8.16 A photosystem consists of 1) a light-harvesting complex and 2) a reaction center. Pigments in the light-harvesting complex pass light energy to two special chlorophyll a molecules in the reaction center. The light excites an electron from the chlorophyll a pair, which passes to the primary electron acceptor. WebWhere α leaf is the leaf absorbance and β reflects the partitioning of the absorbed quanta between PSII and PSI, and R d is the day respiration rate. Light response curves and ΦPSII were measured in gas (98% N 2 and 2% O 2) at nine levels of PPFD (2,000, 1,500, 1,000, 500, 200, 150, 100, 50, 0 μmol m −2 s −1) by the portable photosynthesis system.The slope of …

WebPGA is a three-carbon compound, and the mode of photosynthesis is thus referred to as C 3. In the two other known pathways, C 4 and CAM (crassulacean acid metabolism), the C 3 pathway follows the fixation of CO 2 into oxaloacetate, a four-carbon acid, and its reduction to malate. PGA is formed from 2-carboxy-3-keto-D-arabinitol 1,5-bisphosphate ... Web“ATP is the main fuel of life produced in photosynthesis and oxidative phosphorylation.

WebApr 11, 2024 · Ribulose–1,5–bisphosphate carboxylase/oxygenase (Rubisco) is the rate–limiting enzyme for photosynthesis. Rubisco activase (RCA) can regulate the Rubisco activation state, influencing Rubisco activity and photosynthetic rate. We obtained transgenic maize plants that overproduced rice RCA (OsRCAOE) and evaluated … Web12. Describe the main chemical changes which occur during photosynthesis in: (i) Light reaction (ii) Dark reaction. Solution:-(i) In this phase, light plays a key role. A series of chemical reactions occur in very quick succession, initiated by light and therefore, the phase is called the photochemical phase. The light reaction occurs in two ...
