Differences Between Actin and Myosin
actin_vs_myosin
Actin is the collective molecules of protein from which thin bands are formed. On the other hand, Myosin is the group of protein by which thick bands are formed. Actin and Myosin are responsible for various types of cellular movements, and the most striking one is the muscle contraction, that provides the best-model to understand the role of actin and myosin.
Now, to know the function of actin-myosin, it is necessary to gather bit information about muscles contraction. The cellular and molecular movements in the body are dependent on the muscles cells. Vertebrates have three types of muscles cells – smooth muscles, cardiac muscles and skeletal muscles.
Smooth muscles are known for performing the involuntary motion in the body; cardiac muscles are known for pumping our heart regularly, while skeletal muscles play their role in all kinds of voluntary movements.
Skeletal muscles contain numbers of the muscles fibres, these are a group of numerous cells, that fused to give rise to the single large cells at the time of development. The muscles cells contain numerous nuclei, and its cytoplasm contains myofibrils, that consist of the cylindrical bundles of thick and thin filaments.
The thin filament is made up of a protein known as actin, and the thick one is made fro protein known as myosin, and the these are organized as units of repeating chain known as sarcomeres. The sarcomeres are compelled to give the striated appearance to the cardiac and the striated muscles.
Therefore, it is said that myosin and actin together work at the time of the muscles contractions, where myosin is the precursor protein that plays its critical role in converting the chemical energy (ATP) into mechanical energy. In this article, we will provide vital differences and the points on which actin and myosin vary with their similarities.

BASIS FOR COMPARISON ACTIN MYOSIN
Meaning Actin is the proteins, known to form the thin bands in the myofibrils. Myosin is the proteins, known to form the thick bands in the myofibrils.
Consist of 1. Actin forms a short filament of 2-2.6 um, and it is thin up to 0.005 um.
2. Actin contains troponin and tropomyosin (protein). 1. Myosin forms a long filament of 4.5 um, which has a thickness of 0.01 um.
2. Myosin contains meromyosin (protein).
Found in Actin is present in A and I bands. Myosin is present in A bands of the sarcomere.
Cross bridges Actin does not form cross-bridges. Myosin form cross-bridges.
Surface The surface of actin is smooth. The surface of the myosin is rough.
Number Actin is numerous in numbers. Myosin is less in number, and they are one per six actin filaments.
Slide into Actin slide in H zone at the time contraction. Myosin does not slide at the time of contraction. ..
