What does myosin attach to?
During muscle contraction, myosin cross bridges attach to active sites of ACTIN FILAMENTS.
During skeletal muscle contraction myosin cross bridges attach to active sites of?
During skeletal muscle contraction myosin cross bridges attach to active sites of actin filaments. Actin filaments bind ATP. Their growth is regulated by thymosin and profilin.
During muscle contraction....... attach to ...............?
Troponin
Myosin cross bridges attach to active sites of?
actin (thin) filaments
What structures do the cross bridges attach during muscle action?
actin
What is the region where enzymes attach to their substrates?
The active site.
Where do myosin cross bridges attach during muscle contraction?
Myosin functions as an ATPase utilizing ATP to produce a molecular conformational change of part of the myosin and produces movement. Movement of the filaments over each other happens when the globular heads protruding from myosin filaments attach and interact with actin filaments to form crossbridges. The myosin heads tilt and drag along the actin filament a small distance (10-12 nm). The heads then release the actin filament and adopt their original conformation.
What is the name of the place where an enzyme and substrate attach?
the active point
Where is the region where enzymes attach to their substrates called?
The active site.
What is an enzyme's active site?
An enzyme's active site is a groove or dip in the enzyme that is shaped for a particular substrate to attach to.
How many molecules can attach to one active site?
There can be many but one at a time.
Chordae tendineae are associated with which structure(s)?
Chordae tendineae are associated with the heart, specifically with the atrioventricular valves (tricuspid and mitral valves). They are fibrous cords that attach the valves to the papillary muscles in order to prevent the valves from inverting into the atria during ventricular contraction.
