(a)
To determine: The reason that why it is simpler strategy than the reverse engineering E. coli to be more ethanol tolerant.
Introduction:
“Anaerobic harvest” of food energy is known as fermentation. This condition occurs in the absence of oxygen. In humans, the process of fermentation relies on the first stage that is glycolysis of the
(b)
To determine: The chemical transformation catalyzed by each of three ara enzymes.
Introduction:
The ara genes produce enzymes that convert L-arabinose into L-xylulose-5-phosphate. This is a multistep reaction which includes three different enzymes encoded by different ara genes.
(c)
To determine: The name of the sugar which is converted from arabinose by three ara enzymes.
Introduction:
The ara genes produce three different enzymes encoded by different ara genes that is used to convert L-arabinose .
(d)
To describe: The overall pathway for the fermentation of six molecules of arabinose to ethanol.
Introduction:
“Anaerobic harvest” of food energy is known as fermentation. This is a
(e1)
To determine: The stoichiometry of the fermentation of six molecules of arabinose to ethanol and CO2.
Introduction:
“Anaerobic harvest” of food energy is known as fermentation. This is a metabolic process carried out mainly by yeast and some bacteria. They convert sugar into carbon dioxide and ethanol.
(e2)
To determine: The number of ATP molecules that would be generated in this reaction.
Introduction:
“Anaerobic harvest” of food energy is known as fermentation. This is a metabolic process carried out mainly by yeast and some bacteria. They convert sugar into carbon dioxide and ethanol.
(f)
To explain: The reason that production of 1 ATP per molecule of arabinose is less beneficial for bacterium but better for production of ethanol.
Introduction:
“Anaerobic harvest” of food energy is known as fermentation. This is a metabolic process carried out mainly by yeast and some bacteria. They convert sugar into carbon dioxide and ethanol.
