Answer:
Option (B), (D) and (E).
Explanation:
Allosteric enzymes may be defined as the enzymes that an change their conformation ensemble after binding to an effector molecule. They play important role in cell signalling and metabolic pathways.
Allosteric enzymes do not obey Michaelis- Menten kinetics. They have two binding sites regulatory site and active site. They contain multiple subunit and exist in more active and less active form depending on the type of substrate and regulatory molecule.
Thus, the correct answer is option (B), (D) and (E).

Answer:
Half of the gametes carry one allele of a chromosome, and the other half carry the other allele.Then, fertilization of an egg by a sperm creates a new individual that now possesses two factors for each trait, just like the parents.
Explanation:
The female gamete is called ova which bear 'XX' chromosome and the male gamete is called as sperm that contain 'XY' chromosome.
Fertilization means the fusion of male gamete with the female gamete, which occurs at the ampulla of fallopian tube.This causes formation of zygote which bear haploid cells.
During fertilization, the sperm is capacitated and is attracted towards progesterone which contain CatSper receptor and helps in increase intracellular calcium level.
The tail of sperm disintegrates after the entry of sperm towards the cytoplasm and cortical reaction takes place.Zygote formation takes place after fusion of perm with the ova.
The sperm undergo capacitation that increase the motility and membrane destabilization occurs.
