Explanation / Answer

1.Correct answer is :A. can modify environmental toxins through normal metabolism.

Reason: Bioremediation leads to detoxification of environemental toxins.

2.Correct answer is:C. glucose catabolism.

Reason:Glucose catabolism releases ATP.

3.Correct answer is:A.inner (plasma )membrane

Reason:In gram negative bacteria, the ETC complex is present in the inner plasma membrane.

4.Correct answer is:A.TCA cycle
