1) what is the primary distinguishing factor between anaerobic and aerobic respiration?
group of answer choices
anaerobic respiration uses fermentation whereas aerobic respiration uses glycolysis, the krebs cycle, and the electron transport chain
aerobic respiration gives off carbon dioxide whereas anaerobic respiration gives off oxygen
anaerobic respiration takes place without the use of oxygen whereas aerobic respiration uses oxygen at the end of the electron transport chain
anaerobic respiration only takes place in yeast and bacteria whereas aerobic respiration always takes place in higher organisms such as plants and animals.

2) explain whether this statement is true or false: in cellular respiration, reduction of complex molecules leads to energy release.
group of answer choices
false because breaking down sugars into simpler molecules requires energy
true because sugars are reduced down to release energy
true because sugars are broken down into simpler molecules
false because sugars are oxidized to release energy
