Multiple choice

How many rounds of beta-oxidation are required to completely oxidize a palmitic acid molecule?

  1. 7

  2. 8

  3. 9

  4. 10
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Palmitic acid is a 16-carbon fatty acid, and each round of beta-oxidation removes two carbons. Therefore, 7 rounds of beta-oxidation are required to completely oxidize a palmitic acid molecule.

Multiple choice

Which of the following is an example of an acidic oxide?

  1. Sodium oxide (Na2O)

  2. Carbon dioxide (CO2)

  3. Magnesium oxide (MgO)

  4. Sulfur dioxide (SO2)
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Sulfur dioxide (SO2) is an acidic oxide because it reacts with water to form sulfurous acid (H2SO3).
