The synthesis of 10g of glucose demands an input amounting to ______________ of energy?
Show answer Hide answer
Answer: A. 717.6 Kcal
Explanation
The standard biochemical energy requirement for synthesizing one gram-molecule of glucose is 717.6 kcal. Scaling this thermodynamic calculation down directly yields the energy needed for ten grams. Photosynthetic pathways require this specific energy input to convert carbon dioxide into organic sugars. Photosynthesis captures solar energy and converts it into chemical energy stored in glucose bonds. Thermodynamic principles dictate the exact minimum energy required for specific biochemical synthesis. One mole of glucose has a molecular weight of approximately 180 grams.
Agricultural scientists study photosynthetic efficiency to improve crop yields and energy conversion. Cellular energetics is fundamental for understanding how living organisms store and utilize power. Biofuel production relies on optimizing the natural energy storage mechanisms found in plants. 727 kcal represents an inaccurate estimate that deviates from standard biochemical calculations. 737 kcal overestimates the precise energy requirement for synthesizing this amount of glucose. 747 kcal is incorrect because thermodynamic data points strictly to the lower value.
