Cyanobacteria don't need oxygen to survive they produce oxygen. They where the first ever known organisms on the planet and they produced oxygen in the oceans which was absorbed by iron deposits and then once the iron had oxygen the ocean got the oxygen until it got into the atmosphere and Eukaryota bacteria evolved. So the answer would be: <span>They convert nitrates from the water into nitrogen gas (N2) that is released into the atmosphere.</span>
The answer is C. Enzymes lower activation energy, allowing the reaction to happen more quickly, which is why they are called catalysts.
Fermentation is the process by which a carbohydrate molecule is broken down into alcohol and carbon dioxide in the absence of oxygen. During this process, two molecules of ATP is produced. In the absence of oxygen, pyruvate formed from glycolysis will undergo fermentation process. During the process of fermentation, NADH from glycolysis will be converted back to NAD+. This is necessary in order for glycolysis to continue. Thus, fermentation regenerate more NAD+ and only a few molecule of ATP.
