, Glycolysis occurs when glucose and oxygen are supplied to the cells by the
bloodstream, and it takes place in the cell's cytoplasm. Glycolysis can also occur
without oxygen, a process called anaerobic respiration, or fermentation. When
glycolysis occurs without oxygen, cells make small amounts of ATP

Is pyruvic acid, CO2 & H2O end products

of glycolysis? Yes

Does glycolysis occur during fermentation?

. Glycolysis can also occur without oxygen, a process called anaerobic respiration,
or fermentation. When glycolysis occurs without oxygen, cells make small
amounts of ATP

Does glycolysis reduce NAD?

In the process of glycolysis, NAD+ is reduced to form NADH + H+. If NAD+ is
not present, glycolysis will not be able to continue. During aerobic respiration, the
NADH formed in glycolysis will be oxidized to reform NAD+ for use in glycolysis
again
