Well this is quite easy. The rock would be a igneous rock.
Girls begin their growth spurt around age 10, while boys begin their growth spurt around age 12.
Answer:
Calcium ion is necessary to activate the binding sites on the actin molecules.
The molecule ATP is required each time the mysoin head detached from one sites and reattached.
Explanation:
Depolarization of sarcomere recticulum causes it to release calcium ion. Calcium ion then bind to troponin and reconfigure the complex exposing the binding sites to myosin head on the actin filaments.
The cellular importance of motor is to deliver ATP dependent force impulse to actin molecule.
When ATP molecule bind, the mysoin head detaches from old binding sites of actin, reattaches to new actin monomer. When ATP is hydrolysed, it changes conformation causing actin to slide in respect to myosin.
