WebDec 12, 2024 · This unified model for the G1/S cell cycle transition combines the findings of decades of study, and provides an updated foundation for cell cycle research. ... WebProliferating cells have a higher metabolic rate than quiescent cells. To investigate the role of metabolism in cell cycle progression, we examined cell size, mitochondrial mass, and reactive oxygen species (ROS) levels in highly synchronized cell populations progressing from early G 1 to S phase. We found that ROS steadily increased, compared to cell size …
