Homework Answers
Ans ) The correct answer for this question is -
a) They are used on heavily reduced substrate.
EXPLANATION -
Bioremediation - bioremediation is the remediation ( treatment ) of contamination or polltant with the help of microbes.
On the basis of presence of oxygen it is of two types -
1) Aerobic bioremediation - The type of bioremediation in which oxgen use as a electron acceptor for oxidation of heavily reduced substrate (contaminant) like phenol , PAH ( polyaromatic hydrocarbon ) etc .
Anaerobic bioremediation - The type of remediation in which other than oxygen use for oxidised substrate(contaminant) .
conclusion - aerobic bioremediation used on heavily reduced substrate hence correct option is - a)

Which of the following enhance reaction rate?
Which of the following statements on the strategies enzymes employ to enhance the rate of a reaction are true? Enzymes may cause the substrate to transiently become more protonated or deprotonated than normally. Enzymes may change the equilibrium of the reaction transiently.

Evaluate the following statements about anaerobic conditions as true or false. For clarity’s sake, let’s assume there is absolutely no O2 available, and there hasn’t been for some time. Electrons can no longer be given to the electron transport chain (Ie. reduced electron carriers can no longer be oxidized). True ATP synthase can no longer produce ATP. True The Krebs cycle can no longer run because NADH and FADH2 are products of the cycle, and both accumulate. True Glycolysis cannot continue because...
