Answer 1

Troponin moves away from the active sites on actin permitting cross bridge formation.

Answer 2

Troponin is a regulatory protein that, along with other things, determines muscle contraction. Normally, Troponin binds to active sites on actin, the protein that forms microfilaments. But under the right conditions, it changes position, revealing those active sites. This disclosure makes it possible for myosin, the protein in thick filaments, to form cross-bridges with the active sites on actin thereby enabling muscle contraction.
