|
fascicles
|
|
|
myosin
|
|
|
myofibrils
|
|
|
actin
|
Explanation:
Detailed explanation-1: -The myofilament contractile proteins consist of thick filament myosin and thin filament actin proteins. Bound to actin are a complex of regulatory proteins, which include tropomyosin and troponin-T, C, and I.
Detailed explanation-2: -Muscles are made up of proteins. Actin and myosin are two protein molecules in muscles and are mainly involved in muscle contraction in humans and animals.
Detailed explanation-3: -So, the correct answer is ‘Actin, troponin, and tropomyosin’.
