Which of the following is true about fatty acid usage for energy?Multiple ChoiceEnergy is released from fatty acids anaerobically.Energy is released from fatty acids in a process called lipogenesis.Gram for gram, fatty acids provide more than twice as much energy as glucose. Fatty acids are useful for intense exercise.
Solution
The correct answer is: Gram for gram, fatty acids provide more than twice as much energy as glucose.
Here's why:
-
Energy is not released from fatty acids anaerobically. Fatty acids require oxygen to be metabolized, so they are used in aerobic metabolism.
-
Lipogenesis is the process of synthesizing fatty acids, not breaking them down for energy.
-
Gram for gram, fatty acids do provide more than twice as much energy as glucose. Fatty acids provide about 9 kilocalories per gram, while glucose provides about 4 kilocalories per gram.
-
Fatty acids are not primarily used for intense exercise. During high-intensity exercise, the body primarily uses glucose for energy because it can be metabolized more quickly. Fatty acids are more commonly used for energy during low-intensity exercise or at rest.

Which of the following is a correct statement about the energy systems and fuels used by the body? Question 4 options: a) The lactic acid system is the predominant source of energy after 3 minutes of activity and until activity has reached 20 minutes in length. b) After 20 minutes of sustained activity, fuel for the muscles primarily comes from glucose that is broken down by glycolysis. c) All energy systems are used at all times, but one system dominates depending on intensity and conditioning of athlete. d) About 90 percent of the fuel is derived from fat at rest. e) An anaerobic energy system is the most efficient way to fuel the body for prolonged activity.
