Oats are eaten by humans as oatmeal or rolled oats, and as feed for livestock such as cattle. In order for an oat plant to make the part we eat (the seed), it must flower and be pollinated. Typically, oat plants flower when days are lengthening (i.e., late spring to early summer). What is the best classification for oat plants?

The relationship of free-energy change (?G) to the concentrations of reactants and products is important because it predicts the direction of spontaneous chemical reactions
In the hydrolysis of ATP to ADP and inorganic phosphate (Pi), the standard free-energy change (?G°) is –7.3 kcal/mole. The free-energy change depends on concentrations according to the following equation: ?G = ?G° + 1.42 log10 ([ADP] [Pi]/[ATP]) In a resting muscle, the concentrations of ATP, ADP, and Pi are approximately 0.005 M, 0.001 M, and 0.010 M, respectively. What is the ?G for ATP hydrolysis in resting muscle? (a) –11.1 kcal/mole (b) –8.72 kcal/mole (c) 6.01 kcal/mole (d) –5.88 kcal/mole
