Mama L [17]

By predicting how the sodium-potassium pump becomes integrated into outer cell membrane. The prediction that is false is the mRNA coding into sodium pump is translated into the pump on two ribosomes.

<h3>What is sodium-potassium pump?</h3>

The sodium-potassium pump is an enzyme (an electrogenic transmembrane ATPase) present in the membrane of all animal cells. It is also known as sodium-potassium adenosine triphosphatase, Na+/K+-ATPase, or sodium-potassium ATPase. It serves a number of purposes in cell physiology.

The enzyme Na+/K+-ATPase is activated (i.e. it uses energy from ATP). Three sodium ions are exported and two potassium ions are imported for each ATP molecule used by the pump. As a result, each pump cycle results in the net export of one positive charge.

There are four distinct sodium pump isoforms or subtypes in mammals. Each has distinct qualities and patterns of tissue expression. The P-type ATPase family includes this enzyme.

What is turgor pressure, what causes it, and what does it do for a plant?
ANEK [815]

Turner pressure is simply the force within the plant cell that pushes the cell membrane or plasma membrane against the cell wall.

It is caused by the Osmotic flow of water through the semi permeable membrane.

It helps the plant cells to remain turgid and stand tall so as to prevent it from wilting

Orlov [11]

I believe your Answer would be:

A: Sister Chromatids.

Explanation:

A sister chromatid refers to the identical copies (chromatids) formed by the DNA replication of a chromosome, with both copies joined together by a common centromere. In other words, a sister chromatid may also be said to be 'one-half' of the duplicated chromosome.

Hope I helped, if so may I get brainliest and a thanks?
