Question

8 of 11 mRNA for IPs receptors that do not allow Ca+ release is injected, and then the egg is fertilized o If thesereceptors were made in suficient quantities, they wouldcompete "with normal receptors for available IPs. The result would be increased calcium release from the Golgi complex following fertilization. If these receptors were made in sufficient quantities, they would "compete "with normal receptors for available IPs. The result would be reduced calcium release from the ER following fertilization. If these receptors were made in sufficient quantities, they would "compete" with normal receptors for available calcium. The result would be reduced calcium release from the Golgi complex following fertilization. o if these receptors were made in sl thy wouldompete 'with normal receptos for avaiable cacum. The result would be increased calcium release from the ER following fertilization Submit Request Answer Part C Fluo3, a molecule that fluoresces in response to elevated Ca? levels, is injected into nomal eggs, which are then fertilized Aequorin fluorescence would only be observed at the site of sperm entry into the egg Little fluorescence would be observed at the site of sperm entry into the egg. A wave of GFP aequorin fluorescence would be observed to sweep across the egg, initiating at the site of sperm entry into the egg A wave of aequorin fluorescence would be observed to sweep across the egg, initiating at the site of sperm entry into the egg Submit Request Answer

Explanation / Answer

Answer. Above question, last option 'if these receptors were made in small quantities..... ER following fertilisation'.

Explanation : This type of signal transduction pathway occurs in the Echinoderms. In them, stimulation of the phospholipase C activates the inositol triphosphate(IP3) and diacyl glycerol (DAG). This IP3 helps in the release of Ca2+ from the ER.

Answer part C. Option 3

A wave of GFP aequorin fluorescence... Into the egg.
