What is the first part of the small intestine called?
STatiana [176]

Answer:

The first part of the small intestine is called duodenum

Explanation:

The small intestine is a tightly folded tube which connects to the stomach on the top end and to the large intestine on the bottom end.

The small intestine consists of three parts:

  • duodenum
  • jejunum (absorbs sugars, amino acids, and fatty acids)
  • ileum (absorbs remaining nutrients that did not get absorbed by the duodenum or jejunum)

Duodenum is responsible for completing the first phase of digestion. In this section of the intestine, food is mixed with enzymes and bile which help break down food.

A defective Na+/K+ ATPase pump is isolated from a plasma membrane and studied. Careful measurements in the laboratory determine
Paul [167]

Answer:

The defective Na+/K+ ATPase is not able to dephosphorylate itself.

Explanation:

Na+/K+ ATPase pump cycles between two different forms: the phosphorylated form of the Na+/K+ ATPase has a high affinity for K+ ions and low affinity for Na+ ions. The release of phosphate from ATP and phosphorylation of Na+/K+ ATPase makes the pump to release the bound 3 Na+ ions outside the cell and to bind to the 2 K+ ions from the surroundings. As the Na+/K+ ATPase is dephosphorylated, its affinity for K+ ions is reduced leading to the release of K+ inside the cell.  

A defective Na+/K+ ATPase that is able to pick and bind the K+ ions but is not able to shuttle them across the membrane should be defective to achieve its dephosphorylated form. Without releasing phosphate, the affinity of the pump for K+ ions is not reduced and the pump would not be able to release them to the opposite side of the membrane.
