WebEach myosin head contains a binding site for _____ and a binding site for _____. A) tubulin; GTP B) another myosin molecule; ATP C) kinesin; GTP D) actin; ATP E) none of the above … WebJul 30, 2024 · One part of the myosin head attaches to the binding site on the actin, but the head has another binding site for ATP. ATP binding causes the myosin head to detach from the actin (Figure 4d). After this occurs, ATP is converted to ADP and P i by the intrinsic ATPase activity of myosin.
Webstructure summary. The myosin head is the part of the thick myofilament made up of myosin that acts in muscle contraction, by sliding over thin myofilaments of actin.

WebThe myosin head then moves in which is called the 8. ATP then binds to the which results in myosin disconnecting from actin. 9. The hydrolysis of then results in reenergizing the myosin head which shifts to the loaded position. 10. Ca++ is transported back into the and tropomyosin covers binding sites on actin.
Motor proteins utilizing the cytoskeleton for movement fall into two categories based on their substrate: microfilaments or microtubules. Actin motors such as myosin move along microfilaments through interaction with actin, and microtubule motors such as dynein and kinesin move along microtubules through interaction with tubulin. There are two basic types of microtubule motors: plus-end motors and minus-end motors, depen… photo foundation makeupWebWhen the myosin head is “cocked,” it contains energy and is in a high-energy configuration.
