neuroglycopenic symptoms (dizziness, obtunded or altered mental status) become evident when hypoglycemia occurs (glucose levels < 50). to elevate plasma glucose levels back to normal range (60 to 100), glucagon hormone, released from alpha cells of the pancreas, increases blood glucose levels by directing liver cells to start glycogenosis (breaking down of glycogen, a polysaccharide polymer made up of glucose units) into glucose (a monomer) which is then in turn transferred to the blood.

identify the components of the atom depicted in the image below.
atom structure

Explanation:

Question 13

First, recall the role of glucagon: it promotes glycogenolysis (not glycogenosis) to break down glycogen into glucose. The term in the question is incorrect (glycogenosis is different, glycogenolysis is the breakdown of glycogen). Also, neuroglycopenic symptoms occur with hypoglycemia (glucose <50 is correct for severe cases, and normal range 60 - 100 is correct), but the process name is wrong. So the statement has an error.

In an atom, negatively charged particles are electrons. The red - labeled (with - sign) particles in the atom structure image are electrons (since electrons have a negative charge and orbit the nucleus or are shown as such in typical atom models).

Answer:

False

Question 14

(Note: Since the image of the atom structure is not fully visible, we assume typical atom structure components. In a standard atom model, the red - charged (negative) particles are electrons. If "A" is near an electron, or if we consider the atom's components: protons (positive, in nucleus), neutrons (neutral, in nucleus), electrons (negative, orbiting). But based on the red negative signs, the particles with - charge are electrons. If the image shows electrons (the negative - charged particles), then the component labeled with the - sign (and "A" if associated) is an electron. However, without the full image, we can state the general component: the negatively charged particles in the atom structure (as shown with the - sign) are electrons. If the question is to identify the component of the atom (the red - charged ones), the answer is electron.
