Biosphere is the correct answer! I am glad to help! :)
Explanation:
This observation can be explained by the theory of endosymbiosis. From what scientists have discovered, it can be explained that the double membrane of both chloroplast and mitochondria are as a result of them been subjected to phagocytosis but they were not digested. Their DNA suggest that they were once free living prokaryotes. This agree with the endosymbiosis theory which states that eukaryotic cell organelles developed from prokaryotic cells.
Answer:
Alcoholic fermentation deals with the production of ethanol from pyruvate.
Explanation:
During fermentation the end product of glycolysis known as pyruvate undergoes reduction to generate acetaldehyde by the catalytic activity of pyruvate decarboxylase enzyme which removes one carbon atom from pyruvate thus leading to the formation of acetaldehyde. In this reaction NAD+ is regenerated by the oxidation of NADH.
The acetaldehyde that is formed from pyruvate undergo further reduction to form ethanol by the activity of alcohol dehydrogenase enzyme.NAD+ is also regenerated in this reaction.
