Light vs dark reactions
WebDark reactions occur when light energy is converted into free radicals, which are unstable atoms or molecules with an unpaired electrons. These free radicals can damage cells and cause cancer. Light reactions occur when … WebThe assimilation of carbon into organic compounds is the result of a complex series of enzymatically regulated chemical reactions—the dark reactions. This term is something of a misnomer, for these reactions can take place in either light or darkness. Furthermore, some of the enzymes involved in the so-called dark reactions become inactive in prolonged …

WebThis term is something of a misnomer, for these reactions can take place in either light or darkness. Furthermore, some of the enzymes involved in the so-called dark reactions … 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.
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. 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.
WebDec 24, 2024 · In light-dependent reactions, the energy from sunlight is absorbed by chlorophyll and converted into chemical energy in the form of electron carrier molecules like ATP and NADPH. Light energy is harnessed in Photosystems I and II, both of which are present in the thylakoid membranes of chloroplasts.
