Answer:
Since there is presence of excess tryptophan, the trp operon will be switched off, since the bacterial need not to synthesize.
Explanation:
Understand the following.
The trp operon is a group of gene that encode biosynthetic enzymes for the amino acid tryptophan.
The transcription gene in the operon is switched off when the tryptophan is in excess but is switched on by the bacterium when the tryptophan is low, so that more tryptophan can be produced.

Answer:
Cellular respiration is the process by which living cells break down glucose molecules and release energy. The process is similar to burning, although it doesn’t produce light or intense heat as a campfire does. This is because cellular respiration releases the energy in glucose slowly, in many small steps. It uses the energy that is released to form molecules of ATP, the energy-carrying molecules that cells use to power biochemical processes. Cellular respiration involves many chemical reactions, but they can all be summed up with this chemical equation:
C6H12O6+6O2⟶6CO2+6H2O+Energy
  
where the energy that is released is in chemical energy in ATP (vs. thermal energy as heat). The equation above shows that glucose ( C6H12O6 ) and oxygen ( O2 ) react to form carbon dioxide ( CO2 ) and water  H2O , releasing energy in the process. Because oxygen is required for cellular respiration, it is an aerobic process.
Cellular respiration occurs in the cells of all living things, both autotrophs and heterotrophs.
