Answer:
The correct answer will be option E- 2 & 4.
Explanation:
The sarcomere is a segment made up of thick and thin filaments between the two Z-lines or disc of a myofibril.
Sarcomere structurally can be divided into bands:
- A-band- which is also known as the anisotropic filament is made up of thick filaments called myosin.
- H-zone- the zone in the A-band which appears lighter in color in the microscope
- I-band- an isotropic band made of thin filament called actin.
Upon contraction of muscle, these filaments form an overlapped structure due to which I-band shortens along with H-zone of A- band. Due to the shortening of these bands, only A-band without H-zone and I-band appears between two A-lines. These bands upon relaxation again take their normal form.
Thus, option E- 2 & 4 is the correct answer.
Answer:
Glycogen
Explanation:
The glycogen is composed by a glucose multibranch. Muscles are a reserve for the glycogen but the main reserve is the liver. When the insuline levels go down the glycogen is released thanks to the glycogen phsporylase and when the insuline and carbohydrate levels are high in plasma, the insuline takes those carbohydrates to the liver stimulating other enzimes to produce the glycogen.
