What primary metabolic pathway occurs in harvested crop yields__________________?
Show answer Hide answer
Answer: C. Respiration
Explanation
Respiration continues actively in harvested crops consuming stored reserves and releasing heat. Harvested fruits and vegetables rely on stored carbohydrates to fuel ongoing cellular respiration. This continuing metabolic process accelerates ripening and reduces overall post-harvest shelf life. Harvested agricultural products remain living tissues requiring continuous metabolic energy. Respiration breaks down sugars using oxygen to produce carbon dioxide water and heat. Managing storage temperatures helps slow down respiration rates in commercial facilities.
Cold storage facilities regulate temperatures to minimize respiration heat buildup in crops. Post-harvest loss management depends on controlling respiration to preserve food quality. Agronomists study metabolic pathways to extend the transport viability of fresh produce. Transpiration involves water loss through plant stomata rather than primary harvested metabolism. Growth largely ceases or slows down dramatically once crops are detached from parent plants. Absorption describes root uptake processes which stop entirely upon harvest.
