Answer
At 37 °C, over the 10-minute period, Cell type 1 shows a gradual increase in protein uptake, reaching 20%, whereas Cell type 2 exhibits a significantly higher protein uptake, reaching 40%. This indicates that Cell type 2 is more efficient at protein uptake under higher temperature conditions.
