Concept explainers
To explain: The advantages of using mutant lacking Cytochrome oxidase instead of wild-type yeast for large-scale production of ethanol.
Introduction:
Respiration-deficient mutants are formed from wild-type parents by using mutagenic agents. Cytochrome oxidase is not present in mutants and one of the effects of mutation is that fermentation is not suppressed by oxygen.
To explain:
The reason behind the elimination of Pasteur effect in absence of Cytochrome oxidase.
Introduction:
Louis Pasteur observed that when oxygen is added to anaerobic cells consuming high amount of glucose, rate of glucose consumption declines. Along with the decline in consumption of glucose, accumulation of lactate ceases.

Why is it necessary for this breakdown product to be transported to the liver? For the catabolism of the carbon backbone of these amino acids, there are 7 entry points into the “standard” metabolic pathways. List these 7 entry points and which amino acids are metabolized to these entry points. Please help. Thank you!arrow_forwardBiochemistry Question. Please help. Thank you. You are studying pyruvate utilization in mammals for ATP production under aerobic conditions and have synthesized pyruvate with Carbon #1 labelled with radioactive C14. After only one complete cycle of the TCA cycle, which of the TCA cycle intermediates would be labeled with C14? Explain your answer. Interestingly, you find C14 being excreted in the urine. How does it get there?arrow_forward
