Answer:
In lactic acid fermentation: Glucose --> pyruvate--> lactic acid
Step-by-step explanation:
Some organisms produce their own chemical energy supply, or they may ingest organic substances like glucose and absorb energy. Such species may produce energy provided by producers.
Without the presence of oxygen, they break down chemical energy from glucose by lactic acid fermentation in their cytoplasm.
Within Glycolysis:
- In order to break up glucose into 2 molecules of pyruvate, 4 ATP and 2 electrons holding NADH molecules, 2 molecules of ATP are used.
- Since 2 ATPs are used, this process generates a net 2ATP.
Then...
- Pyruvate is then converted to lactic acid, forming 2 NAD+s, which are used as electron carriers.
