These molecules need to pass through specific proteins or transmembrane proteins embedded in the cell membrane. A specific type of an integral membrane protein.
Answer:
Inside the muscle, calcium facilitates the interaction between actin and myosin during contractions (2,6). ...

Without calcium blood would not clot.
