___________is a major ethylene precursor and its effective conversion requires_______.
Methionine, oxygen
Glucose, oxygen
Methionine, Carbondioxide
Fumarate, Carbondioxide
Methionine is a major ethylene precursor, and its efficient conversion requires oxygen.
One of the crucial precursors to ethylene is methionine, and oxygen is necessary for the conversion to take place.
Along with the aforementioned precursors, pyruvate, fumarate, and propanol are also thought to be potential precursors of ethylene. Peroxidase is needed for the conversion of the majority of these precursors.
Option 1 is the correct answer
