Which of the following is incorrectly matched?
most important steroid; cholesterol
nucleotide; nucleic acid
eicosanoid; triglyceride
monosaccharide; carbohydrate
The Correct Answer is C
A. Most important steroid; cholesterol: Cholesterol is a steroid that serves as a key component of cell membranes and as a precursor for other steroid hormones.
B. Nucleotide; nucleic acid: Nucleotides are the building blocks of nucleic acids such as DNA and RNA, so this pairing correctly represents the relationship between the monomer and polymer.
C. Eicosanoid; triglyceride: Eicosanoids are signaling molecules derived from fatty acids, not triglycerides. Triglycerides are energy-storage molecules, so this pairing is incorrect.
D. Monosaccharide; carbohydrate: Monosaccharides, such as glucose and fructose, are the simplest units of carbohydrates, correctly linking the monomer to the macromolecule.

Correct Answer is B
Explanation
A. Forming a larger molecule: The formation of larger molecules occurs during synthesis reactions, where smaller molecules combine. Bond breaking is not linked with building larger molecules.
B. The consumption of energy: Breaking chemical bonds requires input of energy to overcome the attractive forces holding atoms together. This energy is absorbed from the surroundings, making bond breaking an endergonic process.
C. The release of energy: Energy release happens when new, more stable bonds are formed during reactions. Bond breaking itself does not release energy but instead requires energy.
D. A synthesis: Synthesis refers to constructing complex molecules from simpler ones, which usually involves bond formation rather than bond breaking.
Correct Answer is B
Explanation
Electrolytes are essential for numerous physiological processes, and are critical for maintaining homeostasis. Electrolytes such as sodium, potassium, calcium, and chloride regulate nerve and muscle function, fluid balance, blood pressure, and acid-base equilibrium, all of which are essential for normal body function.
