Glycogenesis is stimulated by
The Correct Answer is {"dropdown-group-1":"A","dropdown-group-2":"A"}
A. Insulin; glucagon and epinephrine: Insulin promotes glycogenesis (storage of glucose as glycogen), while glucagon and epinephrine stimulate glycogenolysis (breakdown of glycogen to glucose).
B. Insulin; aldosterone: Aldosterone regulates sodium and potassium; not directly involved in glucose metabolism.
C. Growth hormone; glucagon and epinephrine: GH has minimal effect on glycogenesis. The second part is correct, but the first is not.
D. Growth hormone; cortisol: Cortisol can promote gluconeogenesis, not specifically glycogenolysis. GH does not drive glycogenesis.
E. Growth hormone; insulin: Insulin does not stimulate glycogenolysis. This pairing is incorrect.

Correct Answer is B
Explanation
A. Metabolic acidosis: This occurs due to loss of bicarbonate (e.g., from diarrhea), not vomiting.
B. Metabolic alkalosis: Vomiting results in loss of hydrochloric acid from the stomach, leading to a relative increase in bicarbonate and metabolic alkalosis.
C. Respiratory alkalosis: Caused by hyperventilation, not vomiting.
D. Respiratory acidosis: Results from hypoventilation or lung disease, not gastrointestinal losses.
E. Lymphatic alkalosis: Not a recognized medical condition.
Correct Answer is E
Explanation
A. Fluid sequestration in the upper limbs: Not typically a physiological response to cold.
B. Hypotonic hydration: Occurs when too much water dilutes body fluids, usually from overhydration, not cold exposure.
C. Hypervolemia: This is fluid overload, unlikely in cold exposure without excess intake.
D. Increased sensible water loss: Sensible water loss refers to loss via urine or sweat—sweating is reduced in cold environments.
E. Increased respiratory water loss: Cold, dry air increases insensible water loss via respiration due to humidification of inspired air.
