In the lowest excited state, the excited chlorophyll has four alternative pathways for disposing of its available energy which of the statement of alternative pathway would be INCORRECT?

#SCPH05 I Biotechnology

Excited chlorophyll can re-emit a photon and thereby return to its ground state—a process known as fluorescence, When it does so, the wavelength of fluorescence is slightly longer than the wavelength of absorption
The excited chlorophyll can return to its ground state by directly converting its excitation energy into heat, with the emission of a photon
Chlorophyll may participate in energy transfer, during which an excited chlorophyll transfers its energy to another molecule
The photochemistry, in which the energy of the excited state causes chemical reactions to occur, the photochemical reactions of photosynthesis are among the fastest known chemical reactions

WRKY plant-specific group of transcription factors that play important role in many plant metabolic and developmental processes such as;

a) It contain a 30 amino acid region named for the conserved amino acid sequence WRKYGQK in its N-terminal domain

b) It is an important regulators of plant–pathogen interactions as well as senescence

c) WRKY53 is involved in the regulation of dark-induced leaf senescence

d) In Arabidopsis, leaf senescence is delayed in knockout mutants of the WRKY53 gene

e) WRKY53 also binds to the promoter of the WRKY53 gene, inhibiting its own expression in a negative feedback loop

Which of the following given prediction about WRKY transcription factor is correct?
