Question

A representative of the pear company explains that pears are typically stored in small, tightly sealed storage bins just after harvesting. He asks whether the ripening process would be different if the same number of pears were stored in a much larger room with better ventilation. Predict whether these two scenarios can be expected to yield the same results, and explain your reasoning.

Answer 1

Workers at a company that grows and sells fresh pears have noticed that the pears seem to mature slowly at first, but then abruptly show extraordinarily quick ripening.

Explains that pears are typically stored in small, tightly sealed storage bins just after harvesting?

"Your pears are under positive feedback control," says Team A. Ethylene accelerates the ripening of fruit by causing both its own production in fruit and the creation of enzymes that catalyze the breaking of cell walls, claims Team B. Both scientific teams presented claims that aid in explaining the acceleration of pear ripening in storage that has been noticed. Because of increased ethylene levels, which indicate increased cell-wall breaking as part of the ripening process, the pears are beginning to ripen.  Since there isn't much ethylene at first, ripening starts out slowly, but as time goes on, more and more ethylene is produced thanks to positive feedback regulation.

• Employees of a business that grows and sells fresh pears have observed that the pears initially appear to mature slowly before suddenly showing an abnormally rapid ripening. This has the company concerned. Officials from the company, perplexed, ask two separate science teams to investigate the issue.

• This implies that ethylene concentrations increase very quickly, which causes ripening to increase similarly quickly.
• The pear company's representative says that soon after harvesting, pears are normally kept in little, tightly closed storage bins. He inquires as to whether the ripening procedure would alter if the same quantity of pears were kept in a space that was larger and had better ventilation.
