Muscle

... are myofibrils ; myofibrils contain sarcomeres , which are composed of actin and myosin . Individual muscle cells are lined with endomysium . Muscle ... types of muscle have significant differences, but all use the movement of actin against myosin to produce contraction and relaxation. In skeletal ...

Myosin

... is a motor protein filament found in muscle tissue . Together with actin filaments, myosin provides the mechanism for muscle contraction , ... of three different filament systems, the thin filaments assembled by actin proteins, the thick filament system consisting of myosin as well as ...

Protein

... and much of the structure of animals is also protein: microtubules, actin , intermediate filaments, collagen and keratin are components of skin, ... and dynein. Muscles are composed largely of the proteins myosin and actin . Working with proteins Proteins can be picky about the environment ...

Pseudopod

... extends a membrane process, named lamellipodium . Polymerization of actin takes place and form filaments at the leading edge, which subsequently will blend into one another to form networks. We suppose that actin polymerization is at the origine of the force propelling the cell ....

Acrosome

... the ovum . Acrosome reaction When the sperm comes in contact with ZP3 in the zona pellucida, this reaction takes place, during which actin polymerizes to form the acrosomal process ; also, the acrosomal vesicle fuses with the plasma membrane of the egg cell, and digestive enzymes are ...

Biomechanics

... biology have much to offer in the way of explaining the active and passive properties of living tissues. For example, the binding of myosin to actin is based on the biochemical reaction, where C a 2 + and ATP move the troponin and tropomyosin to allow for the crossbridges to bind ...
