_glycolysis_ provides the pyruvic acid molecules used in fermentation

true

fermentation allows glycolysis to continue by providing the _nadph_ needed to accept high-energy electrons

NAD+

fermentation is an _aerobic_ process

anaerobic

fermentation occurs in the _mitochondria_ of cells

cytoplasm

_alcoholic_ fermentation givs off carbon dioxide and is used in making bread

true

most organisms perform fermentation using a chemical reaction that converts pyruvic avid to _lactic acid_

true

what causes humans to become lactic acid fermenters

brief periods without oxygen

what are three main sources of ATP available for human muscle cells

ATP already in muscles
ATP made by lactic acid fermentation
ATP produced by cellular respiration

during a race how do your muscle cells produce ATP after the store of ATP in muscles is used

lactic acid fermentation

why does a sprinter have an oxygen debt to repay after the race is over

lactic acid fermentation produces lactic acid to get rid of lactic acid buildup.

a runner needs more energy for a longer race. how does the body generate the necessary ATP

first they use it in muscles, then cellular respiration, then lactic acid fermentation

why are aerobic forms of exercise so beneficial for weight control

body stores energy in the form of glycogen, providing enough energy for 15-20 minutes of activity
