Question 1
Normal arterial blood pH range is approximately?
Correct Answer:
7.35–7.45
Explanation:
Normal arterial blood pH is kept within a narrow window to support enzyme activity and metabolic processes. The typical reference range is about 7.35 to 7.45. Values within this range reflect a balanced acid–base state maintained by buffers (especially bicarbonate), respiratory control of carbon dioxide, and renal control of bicarbonate and hydrogen ions. When pH falls below this range, the blood becomes acidic (acidemia), and when it rises above it, the blood becomes too basic (alkalemia). The other ranges are either too acidic or too alkaline to be compatible with normal physiology.
Question 2
Which amino acid is commonly considered essential in infancy?
Correct Answer:
Histidine
Explanation:
Histidine is commonly considered essential in infancy because growing babies have a rapid rate of development and their bodies cannot yet synthesize enough histidine to meet those needs. This makes dietary histidine crucial for proper growth and protein synthesis during the early stages of life. While other essential amino acids are required throughout life, the special emphasis on histidine in infancy reflects its particularly critical role during rapid growth when endogenous production lags behind demand.
Question 3
This monosaccharide is the 2 epimer of glucose.
Correct Answer:
Mannose
Explanation:
Epimers are stereoisomers that differ at exactly one chiral center. For aldoses like glucose, the carbon next to the carbonyl (C-2) is the first stereocenter, so the 2-epimer means flipping the configuration at C-2. In the common representation of D-glucose, the OH on C-2 points to the right. Inverting that center gives the structure with the OH on C-2 to the left, which corresponds to D-mannose. So the monosaccharide that is the 2-epimer of glucose is mannose. Galactose, by contrast, differs from glucose at C-4, not C-2, so it’s the 4-epimer. Fructose is a ketose, not an aldose, so it isn’t an epimer of glucose. Sucrose is a disaccharide composed of glucose and fructose, not a monosaccharide, so it isn’t an epimer of glucose either.
Question 4
D-glucose and D-galactose
Correct Answer:
Epimers
Explanation:
Epimers are stereoisomers that differ in configuration at exactly one chiral center while the other stereocenters are the same. D-glucose and D-galactose share the same carbon backbone and have the same configuration at all chiral centers except one—the carbon that bears the hydroxyl group at the fourth position. In one sugar that hydroxyl points in one direction, and in the other it points the opposite way. That single difference makes them epimers. This is distinct from enantiomers, which would invert every chiral center and be non-superimposable mirror images, and from anomers, which differ at the anomeric carbon in cyclic forms.
Question 5
A vaccine primarily stimulates which arm of the immune system?
Correct Answer:
Adaptive immune system (B and T cell responses)
Explanation:
Vaccines work by training the body's adaptive immune system to recognize and remember specific pathogens. This system relies on B cells and T cells to mount targeted, lasting responses. B cells produce antibodies (humoral response) and can form memory cells, while T cells handle other targeted roles (cellular response) and also contribute to memory. Innate immunity responds quickly but non-specifically and doesn’t provide long-term protection. Because vaccines are designed to create a specific, lasting defense by generating memory, the arm being stimulated is the adaptive immune system—driven by both B and T cell responses.
