Question

multiple choice:
carbohydrate molecules
a contain the genetic information found in cells
b are the bodys most readily available source of energy
c are the building blocks of cellular membranes
d are composed of c, h, o, and n atoms
e form the regulatory molecules known as enzymes

Explanation:

• Option A: Nucleic acids (like DNA) contain genetic information, not carbohydrates.
• Option B: Carbohydrates, especially simple sugars like glucose, are broken down quickly to release energy. They are the body's most readily available energy source.
• Option C: Phospholipids are the building blocks of cellular membranes.
• Option D: Carbohydrates are composed of \(C\), \(H\), and \(O\) atoms (in a \(1:2:1\) ratio for simple sugars). Proteins contain \(C\), \(H\), \(O\), and \(N\) (and sometimes other elements).
• Option E: Enzymes are proteins (in most cases), not carbohydrates.

Answer:

B. are the body's most readily available source of energy
