WebJan 25, 2024 · Ans: The difference between light and dark reactions: 1. The light reaction is the initial stage of photosynthesis which traps light energy to produce ATP and \ (NADPH\), whereas dark reaction is the second step of photosynthesis which utilises the energy from ATP and \ (NADPH\) to produce glucose. 2. WebThis reaction is also known as light-dependent reaction. 2. Photosynthesis Dark Reaction: ATP + NADPH + CO2 → ADP + NADP + glucose. This phase of photosynthesis does not require light and it takes place in stroma. In this reaction the carbon dioxide (CO2) in the atmosphere combines with hydrogen (H) from water molecules and forms glucose.

Explain the light reaction and dark reaction of photosynthesis?

WebThe light-dependent reactions take place in the thylakoid membrane. They require light, and their net effect is to convert water molecules into oxygen, while producing ATP molecules—from ADP and Pi—and NADPH … http://www.eagri.org/eagri50/PPHY261/lec11.pdf camp parks fitness center

What is the difference between light and dark reactions? - BYJU

WebThe dark reaction of photosynthesis refers to the phase that doesn’t need light energy or photons to complete the cycle and hence also called the light-independent photosynthetic phase. Dark reaction or Calvin cycle … Web8 rows · Photosynthesis comprises two phases: The first phase is the photochemical phase or light-dependent ... Let us have an overview of light reaction and the mechanism involved in light … Web2 of light reaction. The process is called carbon fixation or carbon assimilation. Since Blackman demonstrated the existence of dark reaction, the reaction is also called as Blackman’s reaction. In dark reaction two types of cyclic reactions occur 1. Calvin cycle or C3 cycle 2. Hatch and Slack pathway or C4 cycle Calvin cycle or C3 cycle fisch lampe
