Tropomyosin and troponin are called regulatory proteins because they act like a switch to determine when the fiber can contract and when it cannot.

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.


This protein is produced by a regulatory gene?

a repressor protein


What are the 3 different types of myofilaments?

The three different types of myofilaments are thick filaments, thin filaments, and elastic filaments. Thick filaments are composed of myosin protein, thin filaments are primarily made of actin protein, and elastic filaments (also known as titin) provide elasticity and stability to the sarcomere.


What is the smallest myfibril myofilament muscle fiber or fascicles?

The smallest unit among myofibrils, myofilaments, muscle fibers, and fascicles is the myofilament. Myofilaments are the microscopic protein filaments (actin and myosin) within myofibrils that are responsible for muscle contraction. Myofibrils are bundles of myofilaments, muscle fibers are composed of many myofibrils, and fascicles are groups of muscle fibers.

What protein makes up the thick myofilament?

The protein that makes up the thick myofilament in muscle cells is called myosin. Myosin is a motor protein that plays a key role in muscle contraction by interacting with actin, the protein in the thin myofilament.


What is myofilament?

Myofilaments are the protein fibers within muscle cells that slide past each other to cause muscle contractions. There are two main types of myofilaments: thin filaments, made up of actin protein, and thick filaments, made up of myosin protein. The interaction between these two types of filaments is essential for muscle contraction.


What is the name of the regulatory protein?

There are many regulatory proteins in the human body, such as transcription factors, kinases, and G-proteins. It would depend on the specific context or system you are referring to in order to determine the name of the regulatory protein.

In the control of gene expression in bacteria a regulatory gene a has its own promoter?

The regulatory gene a has its own promoter to enable transcription of the gene. This promoter allows for the synthesis of the regulatory protein encoded by gene a, which can then regulate the expression of target genes in response to specific signals or conditions in the bacterial cell. By controlling the production of this regulatory protein, bacteria can fine-tune their gene expression patterns for adaptation and survival.
