Why do sugar nucleotides, such as udp-glucose, play a role in glycogen synthesis, rather than sugar phosphates, such as glucose-
HACTEHA [7]

Glucose binds to the glycogenin protein to form the glycogen polymer. Glycogen synthase uses UDP glucose as the substrate for polymerization via (1-4) bonds. The branching enzyme has two distinct functions: it breaks the linear chain and forms a branch using a (1-6) linkage.

<h3>What are nucleotides?</h3>

A nucleotide is the primary component of nucleic acids (RNA and DNA). A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA), a phosphate group, and a nitrogen-containing base. DNA nucleotides include adenine (A), cytosine (C), guanine (G), and thymine (T). In RNA, the nucleotide uracil (U) replaces thymine. Polymeric DNA and RNA molecules are composed of long strands of nucleotides.

Juan has been diagnosed with mono, and the doctor wants to determine if his spleen is enlarged. Where (quadrant, etc.) will the
hichkok12 [17]

Answer and Explanation:

  • Where (quadrant, etc.) will the doctor palpate Juan's abdomen?

<em>Under normal conditions in general the spleen can not be palped because of its reduced size. But when it is enlarged it might be easily touched. The spleen is located under the thoracic cage (rib cage) on the left side, between the 8th and 11th ribs. This would correspond to the left superior quadrant (left hemi-belly).</em>

  • What other organs might be compressed by Juan's enlarged spleen?

<em>The enlargement of the spleen and the liver inflammation are symptoms of the mono disease. This enlargement might affect some neighboring organs such as the stomach, which might be displaced and compressed. </em>

  • why is Juan's spleen enlarged and not his stomach or kidney?

<em>The spleen is part of the immunological system and helps the body to fight infections and filter old bloody cells taking them out of the blood current. This organ might get enlarged because blood cells accumulate in its interior. Red blood cells are excessively stored in the spleen, resulting in anemia. The more cells the spleen retains, the larger it becomes, and hence, the more blood cells it retains and destroys. If the spleen is unproperly working, it kills too many red blood cells and accumulates many others.</em>

The Stomach and kidney are not part of the immunity system and they do not filter blood cells, so they do not seem to be affected by their accumulation.
