A biomedical scientist is conducting an experimental study trying to identify the biomolecular mechanism which responsible for muscle contraction. He obtained a rat muscle fiber to know what is the underlying cellular elements that influence muscular contraction. If an embryo rat striated muscle fibers fail to contract in response to an element normally released from the sarcoplasmic reticulum. A deficiency of which of the following would best explain this finding?
