What do the terms P680 and P700 mean in science?
P680 and P700 refer to the specific wavelengths of light that are absorbed by Photosystem II (P680) and Photosystem I (P700) in the process of photosynthesis. These numbers represent the particular chlorophyll molecule's absorption peaks in each photosystem.
The role of p700 during the cyclic reactions is to do what?
The role of P700 during the cyclic reactions of photosynthesis is to receive electrons from plastocyanin and become reduced. This reduction allows it to transfer high-energy electrons to the electron transport chain, ultimately generating ATP.
What is the energy that excites p680 and p700 is supplied by what?
The energy that excites P680 and P700 in photosystem II and photosystem I respectively is supplied by sunlight. More specifically, it is the photons of light energy absorbed by chlorophyll molecules within these photosystems that excites the electrons in P680 and P700 to higher energy states, initiating the process of photosynthesis.
What splits water?
which photosystem (p680or P700) splits water? P680
How can plants capture light?
P680 in photosystem 2 and P700 in photosystem1, respectively.
Which components are directly associated with Photosystem I?
The components directly associated with Photosystem I are chlorophyll a, P700 reaction center, and ferredoxin.
Why are the photosystems in plants called P680 and P700?
The photosystems in plants are called P680 and P700 because they absorb light most efficiently at wavelengths of 680 nm and 700 nm, respectively. This optimal absorption of light allows the photosystems to drive photosynthesis by capturing energy and initiating electron transport within the thylakoid membranes of chloroplasts.
What special pigment do plant cells contain?
Chlorophyll in the chloroplasts and other accesory pigments (p680 in PSII and p700 in PSI)
What will happen if molecules that trap electrons replace p700 molecules and those molecules become saturated with electrons?
If molecules that trap electrons replace P700 molecules, the photosystem I in the chloroplast will not be able to efficiently perform photosynthesis. If those molecules become saturated with electrons, it can lead to a buildup of reactive oxygen species and ultimately damage the photosystem. This can disrupt the electron transport chain and decrease the overall efficiency of photosynthesis.
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.
