How do aerobic and anaerobic respiration compare? a. both aerobic and anaerobic respiration are very efficient and produce a large amount of energy. b. neither anaerobic nor aerobic respiration is very efficient or produces a large amount of energy. c. anaerobic respiration is very efficient and produces a large amount of energy, while aerobic respiration is not very efficient and produces a small amount of energy. d. aerobic respiration is very efficient and produces a large amount of energy, while anaerobic respiration is not very efficient and produces a small amount of energy.

D

Aerobic respiration is more efficient as it causes the complete breakdown of organic molecule(Glucose) into Carbondioxide and water. This results in extraction of large amount of energy which is 38 ATP.

In the contrary anaerobic respiration which occurs during fermentation produces alcohol or lactic acid.It is very less efficient as only 2ATP molecules are produced.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
