The epiglottis ensures that food does not get into the respiratory system so it closes to prevent more food from entering in.

Sometimes, as a person swallows food, the food may accidentally get into the trachea. When this occurs, the epiglottis comes in handy to ensure that food does not enter into the respiratory system.

This occurs because the epiglottis closes the trachea tightly to ensure that no more food enters into the trachea.

The lac operon can be regulated by two distinct methods. Which of the following statements are correct?The lac operon can be act
Ad libitum [116K]

Answer:

  • The lac operon can be activated by the binding of allolactose to the repressor protein, releasing it from DNA and thereby allowing for transcription to occur.
  • In response to low glucose levels, cAMP is upregulated; the binding of cAMP to the cAMP receptor protein triggers the activation of the operon.

Explanation:

Lactose operon or lac operon  (includes lacZ, lacY and lacA genes) is found in some bacteria and the products of its genes are involved in lactose metabolism. So, this operon is active (genes are transcribed) when lactose is present and glucose is absent (or at low level). The operon is regulated by the lac repressor which acts as a lactose sensor and catabolite activator protein (CAP) which acts as a glucose sensor.

When there is lactose (in the form of allolactose) lac repressor detects it and stops being repressor. This enables transcription.

CAP detects glucose (via cAMP) and activates transcription when glucose levels are low.
