Which of the following is NOT true regarding lipid metabolism? 1) it occurs if the body cannot make enough energy from glucose 2) it produces ketone by products 3) it can lead to a fruity smell to urine and breath 4) it will occur after carbohydrate and protein metabolism efforts have been exhausted

Answer

4) it will occur after carbohydrate and protein metabolism efforts have been exhausted

Explanation

When there is insufficient glucose in the body to provide energy, the cells burn fat faster than enzymes can handle ketones, the acidic end products. These ketones build up in the blood and urine and results to a fruity smell on the breath and urine. Lipid metabolism does not occur when the body has exhausted protein and glucose energy stores, rather, only when the present glucose cannot provide enough energy.
