What is the pair of reaction centre chlorophyll a molecule called?
The pair of reaction center chlorophyll a molecules is called the "P680" in photosystem II and "P700" in photosystem I. These names refer to their peak absorption wavelengths of light, with P680 absorbing light most effectively at 680 nm and P700 at 700 nm. These chlorophyll molecules play a critical role in the process of photosynthesis by capturing light energy to facilitate electron transfer.
What describes the role of sunlight in chemical reactions?
it provides energy for some reactions to take place.
What is the role of light in photochemical reactions?
it provides energy
Why was it hard for early scientist to explain how mass changes during reactions?
Early scientists did not have a clear understanding of the concept of atoms and their role in chemical reactions. Without this knowledge, it was difficult for them to explain how mass changes during reactions. The law of conservation of mass had not yet been established, making it challenging to account for mass changes in reactions.
What is the role of STE buffer?
The role of STE buffer is to stabilize DNA and protect it from degradation during processes like DNA extraction and purification. It also helps maintain the pH of the solution to ensure optimal conditions for enzymatic reactions.
Is RuBP produced during cyclic electron flow in the light reactions of photosynthesis?
No, RuBP (ribulose-1,5-bisphosphate) is not produced during cyclic electron flow in the light reactions of photosynthesis. RuBP is a 5-carbon sugar molecule that plays a key role in the Calvin cycle, where it serves as the substrate for carbon fixation by Rubisco enzyme. Cyclic electron flow involves a cyclic pathway of electron transport to generate ATP without the release of oxygen or the production of NADPH.
What is the role of water in cyclic photo phosphorylation?
It provides electrons and protons.
What is the role of energy in photosynthesis?
The energy formed in the light reactions of photosynthesis is used to convert carbon dioxide into glucose during the Calvin cycle (dark reactions).
Describe the role that enzymes play in the process of metabolism?
Enzymes increase the rate of the chemical reactions carried out during metabolism.
What is the role of plant life?
All life in this world are cyclic only. We know the food cycle. Like that plants are placing a good and vital role in life cycle
What is the the role of cyclic AMP in cell proliferation?
Cyclic AMP is a secondary messenger that regulates cell proliferation by activating protein kinase A (PKA). PKA then phosphorylates target proteins involved in cell cycle progression, gene expression, and other cellular processes that drive cell proliferation. Overall, cyclic AMP signaling pathways play a crucial role in coordinating the cell's response to proliferative signals.
What is the role of a propane bond in chemical reactions?
The role of a propane bond in chemical reactions is to provide a source of energy that can be released when the bond is broken. This energy can then be used to drive other chemical reactions or processes.
What is the role of uranium electrons in nuclear reactions?
The role of uranium electrons in nuclear reactions is to facilitate the process of nuclear fission, where the nucleus of the uranium atom splits into smaller nuclei, releasing a large amount of energy. The electrons help maintain the stability of the atom and interact with other particles during the reaction.
What describes the role of sunlight in chemical reactions?
it provides energy for some reactions to take place.
What is the role of light in photochemical reactions?
it provides energy
What is the role of oxygen in chemical reactions?
it makes you breathe
