The statement "When glucose stores are low during exercise, energy can be liberated from adipocytes via lipogenesis" is false. Explanation:
- Lipogenesis is the process of synthesizing fatty acids and triglycerides, essentially a way to store energy in fat cells (adipocytes). This process uses glucose and other substrates to build up fat stores, not to break down fat for energy.
- When glucose stores are low during exercise, the body needs to mobilize energy, which occurs by breaking down stored triglycerides in adipocytes into fatty acids and glycerol. This process is called lipolysis, not lipogenesis.
- Lipolysis liberates energy from fat stores, allowing fatty acids to be used by muscles and other tissues for energy production during exercise.
- Lipogenesis, on the other hand, is active when there is energy surplus and is involved in storing fat, not releasing energy.
Therefore, energy is liberated from adipocytes during low glucose conditions via lipolysis rather than lipogenesis.
