Question

Which molecules act as reaction centres in photosynthesis?

Answer 1

Answer:

The light dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis..the energy storage molecule ATP and the reduced electron carrier NADPH.

Explanation:in plants the light reactions take place in the thylakoid

Membranes of organelles called chloroplast... I hope it makes some sense for you dude...

Answer 2

The Answer is:

A molecule that serves as the hub of a light - dependent reaction during "photosynthesis" is known as a "photosynthetic reaction centre". In the active site, chemicals like "chlorophyll and phaeophytin" are available.

• As a result of their ability to absorb photons, the pigment's electrons is able to migrate toward a excited state.
• In order to produce chemical energy throughout "photosynthesis", the electron should be reduced by using free power that has been created.
• Response zones are found in numerous bacteria in addition to all plants.
• "Photosystem I and Photosystem II", reaction centres found in many plants and  vegetation, have intricate architectures made of many subunits proteins.
• "In a series of protein-bound co-factors, electron transport processes were triggered by molecule resonance, whether it be from sunlight explicitly or even as excited state carried by luminous antenna systems."
• Such co-factors include substances that absorb sunlight, such as quinones, chlorophyll, and pheophytin.
• An electron in some kind of a pigmentation is made active by the particle's power.
• These hydrogen ions of water or hydrogen sulphide are subsequently transferred to carbon dioxide using the free energy created, generating glucose in the process.
• The transformation of incident radiation to chemical energy is indeed the final step in such electron carriers phases.
