During germination, peas sprout and grow. The data table shows the carbon dioxide produced during the germination period of peas under different conditions.ConditionRate of carbon dioxide produced (mL/min)Germinating peas, 10ºC0.01Germinating peas, 20ºC0.02What is the best conclusion?
Answer
A
The rate of cellular respiration in germinating peas is exactly one thousand times the rate of ATP production.
B
Germinating peas at 10ºC create carbon dioxide at a rate of 0.01 mL/min during ATP production.
C
Germinating peas at 20ºC have a higher rate of cellular respiration than germinating peas at 10ºC.
D
The rate of cellular respiration cannot be measured without knowing the rate of ATP production.
Explanation
The table shows that peas at 20ºC produce 0.02 mL of carbon dioxide per minute, compared with 0.01 mL per minute at 10ºC. Carbon dioxide is produced during cellular respiration, so the higher rate indicates a higher rate of cellular respiration at 20ºC. Therefore, choice C is the best conclusion.
