5. A. Inducible.
EXPLANATION: Synthesise rate of enzyme increased due to addition of inducible substance that decrease the activation energy of the reaction.
6. A. Trimer.
EXPLANATION: The lac repressor protein is tetramer, allolactose is dimer and glucose or lactose is monomer, and all these are used in transcription of lac operon , so only trimer molecules are not present.
Question5 Enzymes whose rates of synthesis increase in response to the addition of a small molecu...
A genetically engineered plasmid Ficarries all of the elements of the lac operon, but replaces the structural genes with the reporter gene green fluorescent protein (GFP). The repressor allele cannot bind lactose, and the OC allele cannot be bound by the repressor. Given the following genotypes and growth media that does not contain glucose, indicate in the table below whether you expect to see b-galactosidase activity and glowing green colonies of E. coli by selecting Yes or No. growth media...
1. According to the paper, what does lactate dehydrogenase (LDH) do and what does it allow to happen within the myofiber? (5 points) 2. According to the paper, what is the major disadvantage of relying on glycolysis during high-intensity exercise? (5 points) 3. Using Figure 1 in the paper, briefly describe the different sources of ATP production at 50% versus 90% AND explain whether you believe this depiction of ATP production applies to a Type IIX myofiber in a human....
