2. Which of the following statement is true? Please elaborate why the false statements are false (1 pt). A. The thin filament of skeletal muscle is made of F-actin, troponins and myosin-II B. The thick filament of skeletal muscle is made of microtubules C. Skeletal muscle contracts because the thick filaments get shorter D. Skeletal muscle contracts because of an increase in the overlap of thick and thin filament E. The thick filaments and thin filaments do not interact with one another

Transcript

00:01 Hello students in the question we have to tell about that the whether given statement is true or false.

00:07 The first statement is about thin filaments of skeletal muscle.

00:14 The thin filament is also known as actin filament and this actin filament is made up of three proteins which are actin, second, is proponent and the third one is tropomyosil.

01:00 So on the basis of this information we can say that the given statement is false because myocin is not a component it is tropomyosin.

01:13 So the a statement is false.

01:16 The next statement is about thick filament of skeletal muscle.

01:25 The thick filament of skeletal muscle.

01:32 The thick filament is made up of myocene protein whereas micro tubules which is a cytoskeletal element it is proteinaceous in nature and is involved in cell mortality intracellular transprope in maintaining sense shape.

02:37 So according to this information, we can say that the second statement is also false.

02:45 Statement c is about skeletal muscle contraction.

02:59 So we know that the functional unit of skeletal muscle is sarcomere.

03:25 Both light band and dark band during contraction of skeletal muscle sarcomere shortened but the components sarcomere not shortened so we can see that both thin and thick filament which are the component of sarcomere not shortened so according to this information statement c is also false...
