Under which condition will the metabolic activity in a sea urchin egg most likely be activated even in the absence of sperm?
A) abnormally high levels of carbonic acid in the cytosol
B) abnormally low levels of extracellular oxygen
C) injection of calcium ions into the cytosol
D) depletion of its ATP supplies

Question

Quizplus · Accepted Answer

Injection of calcium ions into the cytosol of a sea urchin egg can mimic the fertilization process, leading to activation of metabolic activities typically triggered by sperm entry. This is because the influx of calcium ions is a crucial signal in the egg activation process following fertilization.

Under Which Condition Will the Metabolic Activity in a Sea
