  • cytochrome- c

  • cytochrome- a3

  • cytochrome- a


106.

Decarboxylation is involved in

  • electron transport system

  • glycolysis

  • Krebs' cycle

  • lactic acid fermentation


107.

The process after glycolysis in anaerobic respiration is known as

108.

Fermentation products of yeast are

  • H2O + CO2

  • Methyl alcohol + CO2

  • Methyl alcohol + water

  • Ethyl alcohol + CO2


D.

Ethyl alcohol + CO2

The yeast causes anaerobic respiration (fermentation). In the fermentation the pyruvate is broken down to form ethyl alcohol (C2H5OH), CO2 and NAD+. The ethyl alcohol is excreted.
