Answer to Question 1

 Maturation of the commodity
 Physical injuries
 Diseases
 Temperature extremes (either too high or low)
 Water stress

Answer to Question 2

The key steps in the ethylene biosynthetic pathway are as follows:
S-adenosylmethionine (AdoMet) is converted to 1-aminocyclopropane-1-carboxylic
acid (ACC) via the enzyme ACC synthase. ACC has two fates:
 The conversion to malonyl ACC (which is an inactive end product) via the enzyme
ACC N-malonyltransferase (ACC-NMtase)
 The conversion to ethylene via the enzyme ACC oxidase

Though Candida and Aspergillus species are the most common fungal pathogens causing invasive fungal disease in the immunocompromised, infections due to previously uncommon hyaline and dematiaceous filamentous fungi are occurring more often today. Rare fungal infections, once accurately diagnosed, may require surgical debridement, immunotherapy, and newer antifungals used singly or in combination with older antifungals, on a case-by-case basis.
