What expand or contract to take the shape of a container?
Gases will expand or contract to take the shape of a container. This is because gases do not have a fixed shape or volume and will fill the available space of their container.
What are the myofilaments called in a muscle cell?
The myofilaments in a muscle cell are called actin and myosin. Actin and myosin are protein filaments that work together during muscle contraction to generate force and movement.
Does a gas changes to a shape and volume?
SHAPE
Does the arrangement of myofilaments produces the striation of a skeletal muscle cell?
Yes.
What protein changes shape due to an action potential?
a voltage-sensitive tubule protein changes shape due to an action potential
When muscles contract do the myofilaments themselves actually shrink?
the myofilaments themselves do not contract, they slide, this is called the Sliding Filament theory, in which the thick filament (Myosin) slides over the thin filament (Actin).
What are the myofilaments called in a muscle cell?
The myofilaments in a muscle cell are called actin and myosin. Actin and myosin are protein filaments that work together during muscle contraction to generate force and movement.
Bundles of myofilaments make up?
Bundles of myofilaments make up
What are two myofilaments that slide past one another to allow muscle cells to contract?
The two myofilaments that slide past one another to enable muscle contraction are actin and myosin. Actin makes up thin filaments while myosin forms thick filaments. During muscle contraction, myosin heads attach to actin filaments and pull them towards the center of the sarcomere, causing the muscle to shorten.
What is a myofibril?
A myofibril is a bundle of contractile filaments (myofilaments), 1-2 μm in diameter, that are arranged in parallel groups in the cytoplasm of striated muscle cells.
What is considered to be a regulatory protein of the myofilaments?
Tropomyosin and troponin are called regulatory proteins because they act like a switch to determine when the fiber can contract and when it cannot.
How does the eye lens focus?
Muscles in the eye surrounding the lens contract stretching it out, flattening it; or relax, letting it thicken. These changes in shape refocus the lens.
What expand or contract to take the shape of a container?
Gases will expand or contract to take the shape of a container. This is because gases do not have a fixed shape or volume and will fill the available space of their container.
What are Thick myofilaments are made of?
Myosin
What does contract amendment mean?
Making changes to a contract. It has nothing to do with the US Constitution.
Does a gas changes to a shape and volume?
SHAPE
What do thick myofilaments extend the length of?
The A band
