sacomeres are a single unit of a muscle fiber multiple sacomeres make up a myofibril
I do believe you are asking about a sarcomere, units of repeating bands that make up the fibers (myofibrils) of a striated muscle.
make more muscle fiber
make more muscle fiber
Amino Acids
Make more muscle fiber.
the two proteins that make up muscles fibers are acting and myosin
Strictly speaking the answer is "mers" - repeating units. Polymers are made from monomers though and this is an acceptable answer.
microfiliments and microtubulars
In DNA, the backbone is made up of alternating deoxyribose sugar and phosphate groups. In RNA, the backbone is made up of alternating ribose sugar and phosphate groups.
microtubules
Muscles make possible every move we make, even when we are sleeping. Your muscles move according to what they are fromed. To be more specific, a muscle is made up of many bundles of muscle fibers. Each of these bundles of fibers is called a motor unit. Each unit has a motor nerve which branches out at its tip. Each muscle fiber, therefore, has its own nerve ending to stimulate it. An electrochemical impulse is transmitted by chemicals from the nerve ending to the fiber, causing the fiber in that motor unit to contract and this is how each muscle of your body moves.
A myofibril is made up of repeating units called sarcomeres. Sarcomeres contain thick and thin filaments that slide past each other during muscle contraction. The protein fibers actin and myosin make up the thin and thick filaments, respectively.
