A germinating seed consumes oxygen at a rate of \(0.45\) mL O\(_2\) per minute per gram of seed tissue. If the seed mass is \(2.5\) g and aerobic respiration yields approximately \(5\) ATP molecules per molecule of O\(_2\) consumed, calculate the total amount of ATP produced per minute. (Assume \(1\) mol of gas occupies \(22.4\) L at STP and Avogadro's number is \(6.022\times10^{23}\) molecules per mole.)

Answer Options

Correct Answer A. ≈2.5×10⁻⁴ mol ATP per minute (≈1.5×10²⁰ molecules)
B. ≈5.0×10⁻⁵ mol ATP per minute (≈3×10¹⁹ molecules)
C. ≈2.0×10⁻⁴ mol ATP per minute (≈1.2×10²⁰ molecules)
D. ≈2.5×10⁻³ mol ATP per minute (≈1.5×10²¹ molecules)
Correct Answer
A
Correct Option:
≈2.5×10⁻⁴ mol ATP per minute (≈1.5×10²⁰ molecules)
