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.

Answer:
The correct answer would be 2 in 4.
According to the question Xo and XO show codominance and express themselves completely when present in heterozygous condition. Cats bearing XoXO show patchwork of black and orange fur and are called tortoiseshell cats.
Xo codes for orange color fur and XO codes for black color fur. In addition, Y chromosome does not contain any gene associated with fur color.
Now, genotype of mother cat is XOXO (orange fur). So, the gametes formed would be XO only.
The genotype of father cat is XoY(black fur). So, the gametes would be Xo and Y.
The cross would lead to the formation of two male cats each having XOY as their genotype and two female cats each with XOXo as their genotype.
Hence, both the male cats would show orange fur and both the female cats would show patchwork of orange and black fur.
Therefore, we can conclude that 2 out of 4 would exhibit tortoiseshell coloring.
Oxygen and carbon dioxide travels to and from tiny air sacs in the lungs, through the walls of the capillaries, into the blood. Blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs.
Answer:
Oxidation of NADH by electron transport chain ensures a continuous supply of NAD+ for glycolysis.
Explanation:
To continue the process of glycolysis, cells must have a continuous supply of NAD+ which is required during one of the reactions of the payoff phase of glycolysis. Two molecules of NADH are formed per glucose molecule during glycolysis. The NADH gives its electrons to the terminal electron acceptors (O2) via electron transport chain. This ensures that the process of glycolysis is continued in cells to breakdown the glucose into pyruvate.
