please i need help with this practice problems

Answer 1

Answer 1 ) (B) Transpeptidases, Cell wall

Answer 2) (B) Lipid A

Answer 3) (B) EMP and TCA

whereas EMP which is also known as the Glycolysis is the single cycle that produces the maximum reducing power.

Answer 4) (B) TCA cycle as it is amphibolic meaning both anabolic and catabolic

(c) CO2 fixation

(D) Nitrogen fixation

Answer 5) (B) NAD

(C) ATP

while glucose provides ATPs to the body and pyruvate provides acetyl CoA that provides energy, it may or maynot ben included.

Answer6 ) (B) Substrate level phosphorylation

I have tried to answer allyour questions to the best of my ability, i hope i come of help to you !:)
