Protein
The two types of protein that are in your muscle cells are actin and myosin. What they do is they slide past each other and that makes a muscle cell work.
Actin and myosin
Actin Filaments
Myosin and Actin
actin and myosin are myofillaments that make up myofibrils (part of a muscle fibre) (so therefore : muscle is an actin or myosin containing structure
Actin and myosin interact in muscle cells.
Myosin and actin
The two filaments involved are myosin and actin. Actin: is the framework and slides over the myosin filament when the muscle is shortened. myosin: is a thick filament Also a sacromere: is made up of the actin and myosin. It is the functional unit of a muscle fibre and extends from z line to z line. A muscle contraction: is many sacromeres shortening ( actin sliding over myosin)
Actin and myosin are the molecules used for muscle contraction.
Actin and Myosin
muscle
Sarcomeres contain myofilaments which consist of actin (thin) and Myosin (thick).
