thanks guys will rate life saver asap, as always.

Glycolysis leads to the production of ____________ and twomolecules of ATP. In the absence of oxygen, fermentation leads tothe production of ______________. Glycolysis plus the citric acidcycle can convert the carbons of glucose to _________ , storing theenergy as ATP, _____________ and ___________.
A.    lactic acid, pyruvate, CO2, NADH, FADH2
B.    pyruvate, lactic acid, CO2, NADH, FADH2
C.    CO2, NADH, FADH2, lactic acid, pyruvate
D.    O2, lactic acid, pyruvate, FADH2
E.    glucose, lactic acid, CO2, NADH, FADH2


At the end of glycolysis, each molecule of glucose has yielded 2molecules of _______, 2 molecules of ________, and a net of 2molecules of _________.
A.    FAD; NAD+; ADP
B.    CO2; NAD+; ADP
C.    lactic acid; ethanol; CO2
D.    pyruvate, NADH, ATP
E.    H2O; CO2; ATP

Explanation / Answer

B. pyruvate,lactic acid, CO2, NADH, FADH2

In glycolysis, glucose with six carbonsis converted into two molecules of pyruvate, each with threecarbons.

In fermentation, pyruvate is reduced byNAD+ producing lactic acid.

In the citric acid cycle, the carbons ofglucose are converted to CO2and the H atoms used toreduce NAD+ and FAD forming NADH andFADH2

2.

D. pyruvate;NADH; ATP
