When a student pulls an all-nighter to cram for an exam, which consequence results due to adenosine buildup and circadian rhythm disruption?

💡 Explanation

Cramming leads to adenosine accumulation and circadian misalignment, which disrupts normal sleep architecture. Because memory consolidation primarily occurs during slow-wave sleep and REM sleep, the disruption causes impaired cognitive function; therefore, memory recall suffers during the exam, rather than improving due to the cramming session itself.
