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 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 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 protein that interacts with actin to form crossbridges?
myosin
The thin filaments of a sarcomere consist of?
The thin filaments of a sarcomere consist of actin, troponin, and tropomyosin proteins. These filaments are responsible for interacting with myosin during muscle contraction, leading to the sliding of filaments and shortening of the sarcomere.
Myofibrils consist of contractile proteins called?
Myofilaments Two types: actin (thin filament) & myosin (thick filament)
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 protein is not in thin filament?
Myosin is a protein that is not found in the thin filament. Myosin is a motor protein that is primarily found in the thick filament of muscle cells and is responsible for muscle contraction. The thin filament contains proteins such as actin, tropomyosin, and troponin.
In the sliding filament mechanism the thin filament is being pulled toward the?
M-line, causing overlap with the thick filament during muscle contraction. This results in the sarcomere shortening and overall muscle contraction.
Which myofilaments actually do the pulling during the sliding filament model of muscle contraction?
thick filaments
