Carotenoids have a linear system of _______bonds and absorb light in the blue-green region and reflect light yellow, ______, and red regions | |
________ acts as secondary light collecters, they draw away excess energy from excited chlorophyll molecules and disspiate the energy as heat | |
The _____________ compares the relative rate of photosynthesis produced by light of various wavelengths | |
The mass of pigment molecules acts as an antenna to collect light energy and transfer the energy to a central __________ | |
The central reaction center will take an excited electron and pass it to the___ molecule | |
Energy is transfered from one ______ molecle to another _____ molecule | |
Photosynthesis that produces oxygen is called _________ photosynthesis | |
The resultant energy from splitting water comes from ______ during the oxidation of water and this energy will be transffered to ______ | |
The two pathwayys of light absorbing reactions are _______ I and photosystem __ | |
Photosystem II boosts ______ from an ebergy level below that of water to a midway point of energy | |
Photosystem I than takes these electrons and raises their energy level above that of ____-- | |
The reaction center of PSII is a dimer of chlorophyll __ that absorbs light most strongly at wavelength of _____ | |
The reaction center of PSI is adimer of chlorphyll a and absorbs most at wavelength of ______ | |
When are electrons are transferred to PSII and PSI, P680 and P700 become _______ charged and revert back to positive when they pass the electrons to an ________ molecule | |
When reaction centers are ______, they will attract electrons passed to them by the antennae | |
Oncw the acceptor molecule becomes negtively charged, we have the conversion of ______ energy to _______ energy | |
One of the steps is the electrons are passed from water to _____ | |
Second step is the electrons are passed from PSII to _____ | |
The third step is electrons are passed from PSI to ______ | |
The electron carriers, as in the mito, are found in the ___________ as large proteins in the thylakoid and these electrons will be used to form a proton gradient | |
The _________ will drive an ATP synthase to make ATP | |
In the chloroplast, the ATP produced will be used to make _________ | |
The ATP needed to support the cell's other activities, outside the chlorplast, will be produced by the _____ | |
PSII has two functions: getting electrons from _____ and producing a _______gradient | |
PSII has twenty polypeptide, most of which are in ______ membrane, two proteins are ____ and ____ which bind the chlorophyll __ dimer and the cofactors for transport of electrons f | |
Most pigments in antennae are in a pigment protein complex called a ______________, which is loacted outside the core of photosystem II which is located just outside the core of ph | |
Light harvesting complex II proteins bind both ______ and ________ | |
PSII splits water in a process called _______ | |
Photolysis require ____ water molecules to be split at the same time | |
PSII can only generate ___ positive charges at a time and you need four to pull off four electrons from two molecules of water | |
PSII has five metal ions 4 _______ ions and 1 _______ which can store the four oxidiing equivalents needed to split two molecules of water | |
The five metal ions and the proteins that hold them in place are called the ___________ complex | |
The electrons from water are harvested in the oxygen-evolving complex, transferred to a _____ residue and then to P680+ | |
Oxidation of two molecules of water results in oxygen plus 4 _____ and 4 ____, the oxygen is waste product for the plant | |
P680 then transfers a single photo-excoted electron to a chlorphyll-like moleculase called ______, which is a chlorophyll molecule without the ______ ion | |
