How does a lack of calcium reuptake to the sacroplasmic reticulum affect the muscle?
The thin filament sites remain open to the binding and stroke of the thick filament and there would be no muscle relaxation without the reuptake of Ca 2+ so the thin filament sites are closed.
What is the difference between a thin and thick atmosphere?
A thin atmosphere is thin and a thick atmosphere is thick
The thin wire in a bulb is called what?
filament
What is the thin coil of wire inside a light bulb called?
If you are talking about an incandescent light bulb then its called a filament. It is thin so that it has a high level of resistance. Current going through the filament causes it to heat up and give off EM radiation in the spectrum of visible light.
Is AAA lava thin or thick?
Thick.
The thin filaments of a sarcomere consist of?
The length of the thick filament is the A band. The A band contains both thick and thin filament because they are overlapping each other. The H band is thick filament only, however, it only covers a portion of width of the thick filament.
Does a lamp with a thick filament draw more current or less current than a lamp with a thin filament?
A lamp with a thick filament will draw more current. What restricts the current flow in the filament is the resistance of the filament which increases as the temperature of the filament increases. A thin filament requires less energy to get heated up that a thick one so less current to achieve threshold resistance. Also a thick filament provides a broader path for current so there is less resistance per increase in degree centigrade. For these two (closely related but distinct) reasons it will require more current for the filament to get heated up to threshold resistance.
What are the thick protein filaments in the cell made of?
The thick filament is composed of the myosin molecule. The thin filament is composed of the actin molecule. Flexing the head of myosin provides the powerstroke.

Myofibrils consist of contractile proteins called?
Myofilaments Two types: actin (thin filament) & myosin (thick filament)
How does a lack of calcium reuptake to the sacroplasmic reticulum affect the muscle?
The thin filament sites remain open to the binding and stroke of the thick filament and there would be no muscle relaxation without the reuptake of Ca 2+ so the thin filament sites are closed.
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 is stronger thin nylon or thick nylon fishing line?
thick
What are the two types of myofilaments?
The two filaments involved are myosin and actin. Actin: is the framework and slides over the myosin filament when the muscle is shortened. myosin: is a thick filament Also a sacromere: is made up of the actin and myosin. It is the functional unit of a muscle fibre and extends from z line to z line. A muscle contraction: is many sacromeres shortening ( actin sliding over myosin)
What chemical ion is responsible for initiating the contraction of a muscle fiber?
Calcium ions bind to the thin filament ( actin ), turn it and expose the binding site to the thick filament (myosin ).
Extension cable long distance thick or thin cable?
Thick to reduce line loss
How do you Use filament in a sentence?
(Filament is a thread or thin wire.)Is the lamp unplugged or is the filament broken in the bulb?A silkworm's cocoon is made from a thin filament which can be twisted into thread.
