Light vs dark reactions
WebApr 6, 2024 · In the following phase of photosynthesis, the dark reactions, ATP and NADPH, are used to produce glucose from Carbon dioxide. The light reaction uses water, light (brought in from outside the cell), NADP+, phosphorus, and ADP (all created by the Calvin cycle) to produce ATP (both used in the Calvin cycle), and oxygen (a waste product). WebStep five of light reactions. ATP is formed when H+ ions in the lumen pass through the enzyme called ATP synthase. Step one of dark reactions. Carbon fixation: CO2 molecules …

WebThe light-dependent reactions and then you have the light independent reactions. I don't like using the word dark reaction because it actually occurs while the sun is outside. It's actually occurring simultaneously with the light reactions. It just doesn't need the photons from the sun. But let's focus first on the light-dependent reactions. WebLight Reaction Vs Dark Reaction The differences between the light and dark reactions are stated vividly using a versatile graphic organizer, the T-chart. Integrate the T-chart to …

WebDec 25, 2024 · Light reactions occur in the thylakoid membranes of the chloroplasts, while dark reactions occur in the stroma, the fluid-filled area surrounding the thylakoids. Light …
WebBoth reactions, the light-depended reaction and the Calvin's cycle OCCURS ONLY in the light (and out of color spectrum, mainly blue and red colors are used thus green reflected into your eye). 1. Light-depended reaction gives you the NADPH 2. You need NADPH in Calvin's cycle And you don't get the NADPH without light. WebJan 24, 2024 · The importance of light reaction is as follows: 1. It is one of the most important phases of the photosynthetic reactions, as photosynthesis demands a huge requirement of light energy. 2. It is the preparatory phase for the formation of sugar that occurs inside the thylakoids, especially those of the grana region. 3.
