Based on the information given in Section 14.3 of your NCERT textbook, can you identify the chemical reaction catalyzed by the enzyme alcohol dehydrogenase?
1.${\mathrm{C}}_{12}{\mathrm{H}}_{22}{\mathrm{O}}_{11}+{\mathrm{H}}_2\mathrm{O}\to 2{\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6$
2.${\mathrm{CH}}_3{\mathrm{COCOO}}^{-}+{\mathrm{H}}^{+}\to {\mathrm{CH}}_3\mathrm{CHO}+{\mathrm{CO}}_2$
3. ${\mathrm{CH}}_3\mathrm{CHO}+\mathrm{NADH}+{\mathrm{H}}^{+}\to {\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}+{\mathrm{NAD}}^{+}$
4. None of these

The maximum concentration of alcohol in beverages that are naturally fermented is about:

Pyruvate is transported into the mitochondria by:

The continued oxidation of acetyl CoA via the TCA cycle requires the continued replenishment of:

At how many points in the TCA cycle is ${\mathrm{NAD}}^{+}$ reduced to NADH + ${\mathrm{H}}^{+}$?

During the conversion of succinyl CoA to succinic acid in TCA cycle:
1. One molecule of ATP is directly synthesized
2. ${\mathrm{NAD}}^{+}$ is reduced
3. FAD is reduced
4. One molecule of GTP is synthesized

The electron transport system in mitochondria is located in the:
1. Inner mitochondrial membrane
2. Outer mitochondrial membrane
3. Inter membrane space
4. Matrix

Ubiquinone receives reducing equivalents via:

Cytochrome c is found:

The number of ATP molecules synthesized from oxidation of one molecule of NADH and one molecule of ${\mathrm{FADH}}_2$ are respectively:
