The light-dependent reactions release oxygen as a byproduct as water is broken apart. In the Calvin cycle, which takes place in the stroma, the chemical energy derived from the light-dependent reactions drives both the capture of carbon in carbon dioxide molecules and the subsequent assembly of sugar molecules. The two reactions use carrier ...

Jan 18, 2022 · Light-dependent reaction is the series of biochemical reactions in photosynthesis requiring light energy that is captured by light-absorbing pigments (such as chlorophyll) to be converted into chemical energy (ATP and NADPH). The light-dependent reaction takes place on the thylakoid membranes of the chloroplast.
The reactions that make up the process of photosynthesis can be divided into light-dependent reactions, which take place in the thylakoids, and light-independent reactions (also known as dark reactions or the Calvin cycle), which take place in the stroma. 1. Chloroplasts have a complex internal structure, and different reactions take place in ...
The net-reaction of all light-dependent reactions in oxygenic photosynthesis is: 2H 2 O + 2NADP+ + 3ADP + 3Pi → O 2 + 2NADPH + 3ATP Key Points Light energy splits water and extracts electrons in photosystem II (PSII); then electrons are moved from PSII to cytochrome b6f to photosystem I (PSI) and reduce in energy.

The light reaction is also known as photolysis reaction and takes place in the presence of light. It usually takes place in the grana of chloroplasts. The photosystems have pigment molecules. In the plants, chlorophyll is one of the primary pigments which actively takes part in the process of light reactions like photosynthesis. The accessory pigme...
Light reaction is the first stage of photosynthesis processin which solar energy is converted into chemical energy in the form of ATP and NADPH. The protein complexes and the pigment molecules help in the production of NADPH and ATP. The process of light reaction is given below- 1. In light reactions, energy from the sunlight is absorbed by the pig...
The light reaction traps the energy from the sun and converts it into chemical energy that is stored in NADPH and ATP.Oxygen is released as the waste product.- 13 min
Light-dependent reactions are certain photochemical reactions involved in photosynthesis, the main process by which plants acquire energy. There are two light dependent reactions: the first occurs at photosystem II (PSII) and the second occurs at photosystem I (PSI). PSII absorbs a photon to produce a so-called high energy electron which ...

Sep 21, 2021 · Generating an Energy Carrier: ATP. In the light-dependent reactions, energy absorbed by sunlight is stored by two types of energy-carrier molecules: ATP and NADPH. The energy that these molecules carry is stored in a bond that holds a single atom to the molecule. For ATP, it is a phosphate atom, and for NADPH, it is a hydrogen atom.
