ATP Synthase: A Marvelous Molecular Machine Designed in all Living Cells

Evolution News and Views

Excerpts:

Everything we do is driven by energy, whether it’s eating a meal, going out for a jog, fighting a cold, or even the seemingly passive task of growing out our hair. The energy currency used by our cells to perform these and many other functions is adenosine triphosphate (ATP), considered by many to be second in importance only to DNA. The majority of ATP is produced by ATP synthase, a quick, efficient, and responsive energy system that is constantly at work to provide organisms with the energy needed for life. The average human body generates over 50kg of ATP every day.

Take a moment and watch the new animation, below.

As the video vividly illustrates, ATP synthase works like a rotary engine. It has many parts we would recognize from human technology, including a rotor, a stator, a camshaft, and the basic components of a rotary engine. Powered by protons, a driveshaft rotates, creating mechanical energy. This allows spent-energy molecules of adenosine diphosphate (ADP) to enter the machine. The mechanical motion of the machine causes ADP to be joined with phosophorous, creating ATP. As the driveshaft continues to spin, the machine releases ATP into the cell, ready to power countless cellular tasks, including DNA and protein synthesis, muscle contraction, transport of nutrients, neural activity, and the generation of electricity in nerves.

After seeing how numerous parts work in coordination to perform vital cellular functions, viewers will find it difficult to believe that these molecular machines could evolve in the unplanned manner required by Darwinism.

Arguments Evolutionists Should Not Use

Arguments Evolutionists Should Not Use

We have a popular article titled, Arguments we think creationists should not use. Indeed, even many misotheistic evolutionists, including Richard Dawkins, have commended the existence of such a page. Well, as the saying goes, ‘What is good for the goose is also good for the gander.’

Here are 21 bad arguments that evolutionists should not use to help further their stance on evolution. Clearly, evolution is about keeping out God, not an open approach to the actual evidence.

The Myth of Science’s Neutrality

The Myth of Science’s Neutrality

There is no pursuit of knowledge that does not seek to affect the world. Science is made by people with interests, intentions and ambitions; and it’s funded by governments and companies with agendas. Scientific development is subject to funding rules, to expectations about outcomes, and to social forces and institutions that shape our research.

Mathematical Proof vs. Scientific Proof: Are They the Same?

Mathematical Proof vs. Scientific Proof: Are They the Same?

Absolute proof is strictly the domain of logicians. In mathematics, for example, once a theorem is proven it is proven for all time and all circumstances. Mathematical proof is absolute. Mathematics, however, is not science. This is a point about which many are confused. Mathematics is a language used by science, but is not itself a science. Mathematical proof and scientific proof are not the same thing at all.

Scientific proof is not really proof at all, in the mathematical sense, but is either verification or disproof. Since scientists deal with a universe that is not of their own creation, they cannot prove their laws absolutely as can mathematicians. Although scientists use the term “scientific proof,” what they really mean is that a particular hypothesis has been verified or disproved. They don’t mean “proof” in the mathematical sense.

I Can Do All Things Through Christ: Natural vs. Supernatural

I Can Do All Things Through Christ: Natural vs. Supernatural

What is better: natural or supernatural? Is the supernatural available to us today? How can one experience the supernatural life?

More Evidence of Scientism as Religion

More Evidence of Scientism as Religion

As shown in our recent documentary C.S. Lewis and the Case Against Scientism, C.S. Lewis compared science to magic in three ways: (1) Science as Religion, (2) Science as Credulity, and (3) Science as Power. In the film, Discovery Institute’s Dr. John West explains that for many people, science (or better, scientism) serves as a quasi-religion. It gives their lives meaning. Evolution in particular provides an overarching, cosmic vision that many find satisfying: a view of something larger than their experience: the birth and ultimate fate of the universe, with mankind struggling against natural odds in its rise to dominance.

To further illustrate, here are a few recent cases from science news of evolutionary thinking serving in the role of religious faith.
