What else can I help you with?
What elements composes chlorophyll?
magnesium chloride
What composes CCl4?
There are two elements.They are carbon and chlorine
What composes mantle?
The mantle is composed of the asthenosphere and the lithosphere.
Is Golgi apparatus is a composes most of the membrane in a cell?
no
What is the protein that composes the thick ligaments?
Collagen is the main protein that composes thick ligaments. It provides strength and structure to support joints and connect bones to other bones.
Myofibrils are made primarily of what?
actin and myosin
What are Myofibrils composed primarily of?
Myofibrils are primarily composed of proteins called actin and myosin. These proteins are arranged in a repeating pattern along the length of the myofibril, forming the sarcomeres, which are the functional units responsible for muscle contraction.
Myofibrils are composed primarily of two protein filaments called?
thick filaments and thin filaments
What are the rod-like structures within the skeletal muscle fiber that contain thin and thick filaments organized into sarcomeres?
The rod-like structures within skeletal muscle fibers are known as myofibrils. These myofibrils are composed of repeating units called sarcomeres, which contain organized arrangements of thin filaments (primarily actin) and thick filaments (primarily myosin). The coordinated contraction of these sarcomeres results in muscle contraction. Myofibrils are essential for the overall function and strength of skeletal muscle tissue.
What makes up myofibrils?
Thin filaments consist primarily of the protein actin, coiled with nebulin filaments. Thick filaments consist primarily of the protein myosin, held in place by tit in filaments.
What surrounds myofibrils?
The sarcoplasmic reticulum are the membranous interconnecting channels and sacs that surround and run parallel to the myofibrils.
What are the longitudinal in the cytoplasm of a skeletal?
Myofibrils
What shortens muscle contraction?
myofibrils
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.
Contractile units of skeletal muscles are?
myofibrils
Muscles contain thousands of what for energy?
myofibrils
What are the longitudinal bundles in the cytoplasm of skeletal?
myofibrils
