Quizplus · Accepted Answer

While researchers have made progress in understanding some aspects of sleep, such as the stages and cycles of sleep and the role of certain brain regions and chemicals, they have not been able to fully explain why we sleep. The other options are not accurate, as researchers have not observed a decrease in protein synthesis during sleep (in fact, some studies suggest it may increase), identified a substance destroyed during sleep, or found a substance created only during sleep (although certain hormones or neurotransmitters may be more abundant during specific stages of sleep).
