Question

Anaerobic respiration converts glucose into energy and byproducts like ethanol, carbon dioxide, or lactic acid. This is possible because carbon can

Answer 1

a) be burned to produce oxygen and energy for cells

b) form bonds with other carbons to create ring structures that can store energy

c) give away its electrons to other atoms so carbon can have any number of bonds

d) be replaced in molecules with other elements that have more valence electrons

I think it is A?

Answer 2

i too think it is A...coz the function of the respiration is that the carbon is completely oxidised to co2 and electron transport is the one due to which v require o2....but ur question is about anaerbic respiration...instead of o2 any other inorganic metals can be acting as terminal acceptor....ok..!! but in fermentation only ur pyruvate from glycolysis is reduced to ethanol,acetaldehyde and so on by getting the reducing equivalence from NADH... there are differences btwn anaerobic respiration and fermentation....understand the difference..then u can make out easily:)
