All of the traits combined that actually show up in the individual - this is the phenotype (the physical, observed expression of genes

Each person has two genes. The DOMINANT TRAIT will show up if that trait is present on one of the two genes.

The RECESSIVE TRAIT can be hidden by the dominant trait. It will only show up if a person has both genes for that trait.

An observable form of an inherited characteristic - A trait

The traits that an individual has inherited, including the ones that do not show up - this is the genotype, as it accounts for the set of genes in our DNA

List the events of the sodium potassium pump in the correct sequence, starting at the TOP.
marishachu [46]

<u>Answer</u>:

<em>Sodium potassium pump works by following several steps. </em>

<u>Explanation</u>:

<em>1. Carrier protein binds three molecules of Na+ </em>

<em>2. ATP is split, phosphate bonds to carrier. </em>

<em>3. Carrier protein changes shape, and deposits Na on the outside of the cell. </em>

<em>4. Carrier binds two molecules of K </em>

<em>5. Phosphate is released. </em>

<em>6. Potassium is released inside the cell </em>

Sodium -potassium pump is essential to maintain the concentration of sodium and potassium outside and inside the cell respectively.

It is the function of sodium potassium pump to transport sodium out of the cell and potassium inside of the cell against a concentration gradient.

<em>Thus it is an active transport mechanism. </em>
