Which of the following actions would increase enzymatic activity in a bacterial cell that normally thrives in the human body? a. slightly increasing the temperature within the optimum range b. increasing the substrate level in the environment beyond saturation c. adding a second substrate that can act as a competitive inhibitor d. placing the bacteria in the refrigerator

Option (1).

Explanation:

Enzymes is the biocatalyst that has the ability to increase the rate of a biochemical reaction of the living organism. Enzymes decrease the activation energy of the reaction.

The bacterial cell has the ability to thrive into the human body and may acts as pathogen. The enzymatic activity of the bacterial cell can be increased by increasing the temperature but the temperature should be in the optimum range of the enzyme.

Thus, the correct answer is option (1).

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
