Answer
Carbohydrates
The primary sources of energy for cells are carbohydrates.
Answer for screen readers
The primary sources of energy for cells are carbohydrates.
More Information
Carbohydrates are the quickest source of energy for cells. Other organic molecules like fats and proteins can also provide energy, but carbohydrates are preferred due to how efficiently they are broken down to supply it.
Tips
A common mistake is to overlook fats and proteins as potential energy sources. While carbohydrates are the primary source, cells can also metabolize fats and proteins, especially when carbohydrate resources are low.
