1. Ethanol -It is advantageous as it is produced from a renewable resource (sugar from plants such as sugar cane) and could be seen as carbon neutral. It helps the economy as sugar cane can be grown in poorer, hotter climates.
- The negatives are that it is impure, and more steps are needed afterwards to purify the ethanol obtained.
2.Lactic Acid-There is a relatively large amount of glycogen stored in the body and so this system can provide more ATP than the PC system.
-The by-product – lactic acid – lowers pH in the muscle cell making it more acidic. This prevents enzymes from functioning properly and so causes muscle fatigue.
3.carbon dioxide- The carbon dioxide given off during fermentation supplements the carbon dioxide given off during the Krebs cycle and causes bread to rise.
- The carbon dioxide by-product bubbles through the liquid and dissipates into the air.
