Biochemistry Quotes

We live in a world where unfortunately the distinction between true and false appears to become increasingly blurred by manipulation of facts, by exploitation of uncritical minds, and by the pollution of the language.

~ Arne Tiselius

The conclusion of intelligent design flows naturally from the data itself—not from sacred books or sectarian beliefs. Inferring that biochemical systems were designed by an intelligent agent is a humdrum process that requires no new principles of logic or science. It comes simply from the hard work that biochemistry has done over the past forty years, combined with consideration of the way in which we reach conclusions of design every day.

~ Michael J. Behe

Molecular machines display a key signature or hallmark of design, namely, irreducible complexity. In all irreducibly complex systems in which the cause of the system is known by experience or observation, intelligent design or engineering played a role in the origin of the system... We find such systems within living organisms.

~ Scott A. Minnich

The night before a biochemistry class, I read the lecture notes from last year. I look at the pictures in the book. I read some of the book.Now, I've got the general concept. Sure...There's a couple of details to fill in and a few things to memorize. but that's no big deal. I've got the big picture and that's all I need.Bring it on professor. I'm ready.That's right.The next day, I'm a goalie sitting in the front row.Nothin gets past me...My ability to comprehend a biochemistry lecture just went up from 30% to 95%.I went on to score 780 out of a possible 800 on the medical school biochemistry boards exam (USMLE 1). Given that the 99th percentile began around 690, this was one of the highest scores in the USA, perhaps the highest.

Every day, hundreds of observations and experiments pour into the hopper of the scientific literature. Many of them don't have much to do with evolution - they're observations about the details of physiology, biochemistry, development, and so on - but many of them do. And every fact that has something to do with evolution confirms its truth. Every fossil that we find, every DNA molecule that we sequence, every organ system that we dissect, supports the idea that species evolved from common ancestors. Despite innumerable possible observations that could prove evolution untrue, we don't have a single one. We don't find mammals in Precambrian rocks, humans in the same layers as dinosaurs, or any other fossils out of evolutionary order. DNA sequencing supports the evolutionary relationships of species originally deduced from the fossil record. And, as natural selection predicts, we find no species with adaptations that only benefit a different species. We do find dead genes and vestigial organs, incomprehensible under the idea of special creation. Despite a million chances to be wrong, evolution always comes up right. That is as close as we can get to a scientific truth.

~ Jerry A. Coyne

The inhibition of an inhibitor leads to the activation of an inhibitor of an inhibitory pathway. This is the point where most people might be tempted to give up on biochemistry!

~ Chris Cooper

I would not be among you to-night (being awarded the 1964 Nobel Prize in Physiology or Medicine) but for the mentors, colleagues and students who have guided and aided me throughout my scientific life. I wish I could name them all and tell you their contributions. More, however, than anyone else it was the late Rudolf Schoenheimer, a brilliant scholar and a man of infectious enthusiasm, who introduced me to the wonders of Biochemistry. Ever since, I have been happy to have chosen science as my career, and, to borrow a phrase of Jacques Barzun, have felt that 'Science is, in the best and strictest sense, glorious entertainment'.

~ Konrad Bloch

During this time (at high school) I discovered the Public Library... It was here that I found a source of knowledge and the means to acquire it by reading, a habit of learning which I still follow to this day. I also became interested in chemistry and gradually accumulated enough test tubes and other glassware to do chemical experiments, using small quantities of chemicals purchased from a pharmacy supply house. I soon graduated to biochemistry and tried to discover what gave flowers their distinctive colours. I made the (to me) astounding discovery that the pigments I extracted changed their colours when I changed the pH of the solution.

~ Sydney Brenner

Information and complexity go hand in hand.

~ Lee Spetner

Chloroplasts bear chlorophyll; they give the green world its color, and they carry out the business of photosynthesis. Around the inside perimeter of each gigantic cell trailed a continuous loop of these bright green dots. They spun . . . they pulsed, pressed, and thronged . . . they shone, they swarmed in ever-shifting files around and around the edge of the cell; they wandered, they charged, they milled, raced . . . they flowed and trooped greenly . . . All the green in the planted world consists of these whole, rounded chloroplasts . . . If you analyze a molecule of chlorophyll itself, what you get is one hundred thirty-six atoms of hydrogen, carbon, oxygen, and nitrogen arranged in an exact and complex relationship around a central ring. At the ring’s center is a single atom of magnesium. Now: If you remove the atom of magnesium and in its place put an atom of iron, you get a molecule of hemoglobin. The iron atom combines with all the other atoms to make red blood, the streaming red dots in the goldfish’s tail.
