What molecule is required each time the myosin head detaaches from one site and reattaches to another

Biology
1 answer:
julsineya [31]3 years ago
5 0

Answer:

The adenosine triphosphate (ATP) molecule

Explanation:

The actin filaments are often associated with myosin to produce muscle contraction. These myosin filaments are considered to be 'molecular motors' capable of converting the chemical energy contained in the ATP molecule to mechanical energy, thereby producing cell movement. Myosin heads bind to actin filaments in order to generate a power stroke. When the adenosine triphosphate (ATP) molecule binds to myosin, the myosin head detaches to the actin filament. During this process, the ATP molecule is broken down and then the released energy is used by the myosin filament to return to its original position.

Leni [432]

A true-breeding specimen seems to be homozygous, thus, the blue color flowers must exhibit the genotype BB and the yellow ones must have possessed the genotype YY.  

In the given case, when one crosses a flower with genotype BB and other with genotype YY, all the offspring will be BY. As in the next generation, all the flowers appear blue, thus, the blue allele must be dominant.
