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?

Following statements regarding to the molecular processes of capacitation.

A. The sperm cell membrane is altered by the removal of albumin by cholesterol in the female reproductive tract.

B. Particular proteins or carbohydrates on the sperm surface are lost during decapacitation.

C. The membrane potential of the sperm cell becomes more positive as potassium ions leave the sperm. This change in membrane potential may allow calcium channels to be opened and permit calcium to enter the sperm.

D. Calcium and bicarbonate ions are critical in activating cAMP production and in facilitating the membrane fusion events of the acrosome reaction.

E. As a result of cAMP formation, protein phosphorylation occurs. Once they are phosphorylated, some proteins migrate to the surface of the sperm head. One of these proteins is izumo, which is critical in sperm-egg fusion.
