At onset of muscle contraction, myoglobin (Mb) immediately releases its bound O 2 to the mitochondria. Accordingly, intracellular O 2 tension (P mb O 2) markedly declines in order to increase muscle O 2 uptake (m O 2).t onset of muscle contraction, myoglobin (Mb) immediately releases its bound O 2 to the mitochondria.

Lesson Summary. In summary, myosin is a motor protein most notably involved in muscle contraction. Actin is a spherical protein that forms filaments, which are involved in muscle contraction and other important cellular processes.Tropomyosin is a long strand that loops around the actin chains in the thin filament. Troponin is a protein that helps hold tropomyosin in place on the actin filament.A muscle contraction consists of a series of repeated events. First, calcium triggers a change in the shape of troponin and reveals the myosin-binding sites of actin beneath tropomyosin.n summary, myosin is a motor protein most notably involved in muscle contraction.
