What filament is connected to the Z line thick or thin?
The filament connected to the Z line in a muscle cell is thin filament, specifically actin filament. Thick filaments (myosin) are connected to the M line in the sarcomere.
What are the filsments of DNA and protein?
In essence, a protein filament is a long strand (aka filament) that's made of protein (hence, "protein filament"). So they are composed of smaller, protein subunits, which are single protein molecules.
How many different types of histone subunits are present in a nucleosome?
the number of histone subunits in a nucleosome is?
Does protein has polymers with many subunits?
Proteins are not polymers.
Two lamps one with thick filament and one with a thin filament are connected in parallel to a battery . What explains why the lamp with the thicker filament burns more brightly?
The lamp with the thicker filament has a lower resistance compared to the one with the thin filament. According to Ohm's law, lower resistance allows more current to flow through the thicker filament when connected in parallel to the same voltage source. This increased current results in a higher power output (P = I²R), causing the lamp with the thicker filament to burn more brightly.
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 does a filament mean?
A protein filament is a long chain of protein subunits, like those found in hair, muscle. They are always bundled together for strength and rigidity.
What filament is connected to the Z line thick or thin?
The filament connected to the Z line in a muscle cell is thin filament, specifically actin filament. Thick filaments (myosin) are connected to the M line in the sarcomere.
The thick filament that has cross-bridges?
myosin

What is the thickness of the filament in light bulbs?
the filament is neither too thick nor too light

What filament is responsible for the pulling and what filament is pulled in the sliding filament theory?
In the sliding filament theory of muscle contraction, the thin filament (actin) slides over the thick filament (myosin). Myosin is responsible for pulling the actin filaments towards the center of the sarcomere during muscle contraction.
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.
Myofibrils consist of contractile proteins called?
Myofilaments Two types: actin (thin filament) & myosin (thick filament)
Which protein of the sarcomere is the thick filament made of?
The thick filament of the sarcomere is primarily made of the protein myosin. Myosin molecules aggregate to form the thick filaments, which interact with the thin filaments (primarily composed of actin) during muscle contraction. This interaction is crucial for the sliding filament model of muscle contraction, allowing muscle fibers to shorten and generate force.
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).
