The Breakdown of ____ into Cellular Energy Can Involve Glycolysis

Question

The breakdown of ____ into cellular energy can involve glycolysis.  
A) carbohydrates
B) fats
C) proteins
D) carbohydrates and fats
E) fats and proteins

Accepted Answer

The breakdown of both carbohydrates and fats can involve glycolysis, especially in the initial steps for carbohydrates. Fats can be broken down into glycerol and fatty acids, where glycerol can enter the glycolysis pathway. Proteins are primarily broken down into amino acids and do not directly enter glycolysis, although some of their breakdown products can enter the cycle in other forms.
