Coffee Maker

The newlywed Blonde went to the store to ask how to operate the new coffeemaker received as a wedding gift. The salesman carefully explained how everything worked; how to plug it in, set the timer, go to bed, and upon rising, the coffee is ready.

A few weeks later the goober was back in the store and the salesman asked her how she liked the coffee maker.

"Wonderful!" she replied, "But... it's just awfully inconvenient to have to go to bed every time I want to make a pot of coffee."

Sir Arthur Harden

Born 12 Oct 1865; died 17 Jun 1940 at age 74.English biochemist who shared (with Hans von Euler-Chelpin) the 1929 Nobel Prize for Chemistry for work on the fermentation of sugar and the enzyme action involved. Harden continued the work of Eduard Buchner who had discovered that such reactions can take place in the absence of living cells. Harden demonstrated that the activity of yeast enzymes included both large protein molecules and essential coenzymes - small nonprotein molecules. This was the first evidence for the existence of coenzymes. Harden also discovered that yeast enzymes are not broken down and lost with time, but that the gradual loss of activity with time can be reversed by the addition of phosphates, which are now known to play a vital part in biochemical reactions.
