If an atom gains or loses an electron, it is an ion. When one atom which has lost an electron comes in contact with one which has gained an electron, they form an ionic bond. Together their charge is neutral.

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.

What specializations might allow one tissue to produce a hormone, and another to facilitate nutrient exchange? is it possible fo

noname [10]

Differential gene expression patterns allow one tissue to produce a hormone, and another to facilitate nutrient exchange. The same organ can serve both functions because it can synthesize different proteins.

<h3>Diferential gene expression</h3>

Gene expression refers to the differential process by which different genes are expressed (transcribed and then translated) in different cell types.

Gene expression enables different functions due to the production of different types of proteins which may have both enzymatic and structural functions.

A specialized cell type or organ can synthesize different proteins and also generate other molecules (either enzymes or structural proteins) due to the process of cell differentiation.
