Excitation-contraction coupling refers to the series of events that begins with the excitation of the sarcolemma in response to stimulation by a neurotransmitter, and results in the release of calcium ions from the sarcoplasmic reticulum.
Hence, option D is the 1st process that starts the excitation-contraction coupling.
The correct answer is: Endoplasmic reticulum.
One of the functions of the endoplasmic reticulum is transport of secretory proteins. Synthesized proteins are transported in vesicles to the Golgi apparatus.
Gastric chief cells have a high rate of enzyme secretion such as pepsinogen and gastric lipase. It is the cell also responsible for secretion of chymosin.
I believe the answer would be B where the condensed chromosomes line up at the equator of the cell.
Condensation, because when water vapor turns into water again it needs to release energy to do so. Its like turning ice into water again.
