The release of an inorganic phosphate from the myosin molecule directly results in ________
zhuklara [117]

Answer:

power stroke

Explanation:

  • The process of muscle contraction requires several steps.
  • The most famous theory on how the contraction and relaxation of muscles take place is the sliding filament theory.
  • However, this theory has been refined and one important addition to it is the mechanism by which myosin can pull actin and cause shortening of the sarcomere.
  • For the movement of myosin, it binds and releases actin and forms cross bridges.
  • Myosin is subdivided into two regions - S1 and S2. The contraction of the S1 region is what constitutes the power stroke.
  • An important requirement of the power stroke is the hydrolysis of ATP to release an inorganic phosphate which provides energy for the process.

dalvyx [7]

Answer:

a). Major products of glycolysis include pyruvate, ATP , and NADH

b) Glycolysis is the process by which glucose is converted to two molecules of pyruvate.

Explanation:

Glycolysis is a process in which a glucose molecule is broken down into two molecules of pyruvate. The process of glycolysis occurs without oxygen therefore it can occur in both aerobes and anaerobes.

The process of glycolysis occurs in the cytoplasm of the cell and the products of glycolysis are 2 molecules of pyruvate, 2ATP, and 2 NADH molecule. Then the pyruvate molecule gets into mitochondria which it's complete oxidation takes place. Therefore the right answer is a and b.
