This article examines the changes in leaf respiration during the night, specifically focusing on the decrease in leaf respiratory O2-uptake and CO2-efflux. The authors analyze data from various studies and find that these decreases indicate a decrease in leaf mitochondrial electron transport and ATP demand. The article emphasizes the need for further research to understand the underlying mechanisms and species-specific differences in nocturnal changes in leaf respiration. The authors also discuss the implications of changes in the respiratory quotient (RQ), suggesting that the relative composition of respiratory substrates may shift during the early hours of the dark period. They highlight the importance of studying factors that affect RQ, such as substrate composition and demand for respiratory intermediates. Overall, this information is valuable for understanding the relationship between environmental and metabolic regulation of respiration and its impact on carbon uptake. [Extracted from the article]
