What are two major proteins in the sarcomere?
The two main filaments composing the sarcomere are action and myocin.
Sarcomere think filaments are linked laterally by proteins of the?
z line
Where is the sarcomere located?
Muscle
What are the 3 sections along the length of sarcomere?
The three sections along the length of a sarcomere are the A band, the I band, and the H zone. The A band is the dark region in the center of the sarcomere that contains both thick and thin filaments, while the I band is the light region at the ends of the sarcomere that contains thin filaments only. The H zone is the region in the center of the sarcomere where only thick filaments are present.
What are the outer boundaries of the sarcomere?
Z-lines
What are two major proteins in the sarcomere?
The two main filaments composing the sarcomere are action and myocin.
Sarcomere think filaments are linked laterally by proteins of the?
z line
What do sarcomere contain?
Sarcomeres are composed of actin (thin filaments) and myosin (thick filaments).
Are sarcomere thick filaments linked laterally by proteins of the Z line?
No, the M line
How can macromolecules be organized?
be organized by lipids proteins and nucleic acids
When DNA and proteins are packaged into organized cellular structures what is produced?
proteins
What change occur in sacomere during muscle contraction?
The sarcomere itself will become shorter.The sarcomere will shorten.
What is the functional unit of a muscle called?
Sarcomere
Can macromolecules be organized into vitamins lipids proteins and nucleic acids?
No. It is false.
DNA and proteins are packaged into organized cellular structures known as?
DNA and proteins are packaged and organized into chromosomes. Just to clarify generally protein is everywhere, but is made within a cell in organelles called ribosomes.
Is Sarcomere and sarcolemma the same thing?
sarcomere and sarcolemma are two different things. a sarcomere is between two d zisks of a myofiber (muscle fiber). a sarcolemma is a plasma membrane. there are many sections of sarcomere under the layer of sarcolemma.
Specifically what is responsible for the banding pattern in skeletal muscle cells?
Prosomes form sarcomere-like banding patterns in skeletal, cardiac, and smooth muscle cells.Actin and Myosin proteins
