Question

what are types of contractile proteins present in miscle?​

Answer 1

Answer:

Actin and myosin are the 2 contractile proteins found in muscles

Answer 2

Contractile proteins of muscle fibre are:

• Actin
• Myosin

━━━━━━━━━━━━━━━━

Actin:

• Band of Actin protein is also called Isotropic band or I band

• Actin filaments are polymerised proteins.

• The actin filaments are made when two filamentous actin helically wond to each other.

• The filamentous actin is also called F-actin

• F-actin is made up of G-actins or Globular actins.

━━━━━━━━━━━━━━━

Myosin proteins:

• Band of myosin proteins is also known as Anisotropic band or A-band

• Myosin filaments are also polymerised proteins.

• Many monomeric proteins are called Meromyosins.

• Meromyosins constitute one thick filament.

• They have an active ATPase enzyme and has ATP and actin binding sites.
