What happens to fatty acids before they can be used as a substrate for respiration?

What happens to fatty acids before they can be used as a substrate for respiration?
  1. They are converted into glucose
  2. They are degraded into glycerol
  3. They are degraded into acetyl CoA
  4. They are used directly as a substrate

Solution

Fatty acids would need to be broken down into acetyl CoA before entering the respiratory pathway when it is used as a substrate.
