Is it true that calcium signaling is essential for muscle contraction and fertilization?

Yes. Extensive physiological and cellular evidence establishes that calcium signaling plays a vital, non-negotiable role in mediating both muscle contraction and fertilization across species.

Verdict: SUPPORTED · 7 sources for, 0 against · Last checked

The analysis

The claim is specific, testable, and directly addressed by multiple provided papers spanning muscle physiology and reproductive biology. All relevant literature overwhelmingly supports the fundamental role of calcium in both excitation-contraction coupling and fertilization/egg activation. Therefore, the verdict is SUPPORTED.
