The pen may be mightier than the sword, but a magic wand is more powerful than either, or at least according to this year's Forbes' list of the world's richest celebrities. Harry Potter author JK Rowling earned more than any other celebrity, according to the annual Celebrity 100 list, taking home $300m (Â£150m) last year. There were other strong British performances from Keira Knightley, announced as the world's second best paid female actor, Potter actor Daniel Radcliffe and David Beckham.
A facultative anaerobe is, simply speaking, an organism which possesses the ability to survive in an environment containing oxygen while growing even more efficiently in an environment without oxygen. Facultative anaerobes can optionally function without oxygen by two main mechanisms; fermentation and alternate terminal electron acceptors. In fermentation, glycolysis is performed and pyruvate is converted to a fermentation product, reducing NAD+ back to NADH. (Note that there are likely many variations on this).
Lactic Acid Fermentation. Glycolysis is a metabolic reaction in which glucose is broken down to produce a substance called pyruvate. Pyruvate is the end product of the process of glycolysis, and it supplies energy to the muscles.Pyruvate provides energy to cells when oxygen is present by oxidizing to produce carbon dioxide. In anaerobic conditions, the pyruvate ferments to produce lactic acid.The lactic acid is used by your muscle cells to continue the process of metabolism of glucose for energy production.actic acid fermentation causes you to feel a burning sensation in your working muscles during exercise but not after. This is because of the process that your muscle cells undergo to produce energy.
