What is the most accurate conclusion that can be drawn from the "Glucose Uptake over Time in Guinea Pig Red Blood Cells" graph?
A: 15-day-old guinea pig red blood cells exhibit a higher rate of glucose uptake than 1-month-old guinea pig red blood cells, reaching a higher saturation level.
B: Glucose uptake in both age groups continuously increases over time without saturation.
C: At 30 minutes, 1-month-old guinea pig cells have taken up more radioactive glucose than 15-day-old cells.
D: The rate of glucose uptake is identical for both 15-day-old and 1-month-old guinea pigs after 40 minutes.
Explanation
The graph clearly shows that the red line 15-day-old guinea pig rises more steeply and reaches a higher plateau than the blue line 1-month-old guinea pig , indicating a faster rate of glucose uptake and a higher saturation level for the younger animals.
