Which statement explains how ATP and its phosphate groups are related to the energy that is used in plant processes?

A
ADP loses a phosphate group to create ATP, which stores energy for making sugars.
B
ADP gains a phosphate group to create ATP, which stores energy for making sugars.
C
ADP loses a phosphate group to create ATP; this process instantly releases energy for making sugars.
D
ADP gains a phosphate group to create ATP; this process results from sugar production.

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?

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.
