Psalm 139:14
"ATP synthase is one of the most astonishing and elegant nano-machines of the cell, a proton-powered rotary engine pumping out life’s energy currency nonstop.
How it could have arisen by blind, unguided processes is rarely addressed in the origin-of-life community.
HOW ATP synthase work: Life depends on an incredible enzyme
called ATP synthase, the world’s tiniest rotary motor.
This tiny protein complex makes an energy-rich compound, ATP (adenosine triphosphate). Each of the human body’s 14 trillion cells performs this reaction about a million times per minute. Over half a body weight of ATP is made and consumed every day!
All living things need to make ATP, often called the “energy currency of life”.

ATP is a small molecule with a big job: to provide immediately usable energy for cellular machines. ATP-driven protein machines power almost everything that goes on inside living cells, including manufacturing DNA, RNA, and proteins, clean-up of debris, and transporting chemicals into, out of, and within cells.
Other fuel sources will not power these cellular protein machines for the same reasons that oil, wind, or sunlight will not power a gasoline engine.
---This protein complex contains at least 29 separately manufactured subunits that fit together into two main portions: the head and the base.

When a stream of tiny hydrogen ions (protons) flows through the base and out the side of ATP synthase, passing across Mechanism of ATP synthase.
....they force the axle and base to spin. The stiff central axle pushes
against the inside walls of the six head proteins, which become slightly deformed and reformed alternately. Each of your trillions of cells has many thousands of these machines spinning at over 9,000 rpm.
The spinning axle causes squeezing motions of the head so as to align an ADP next to a phosphate, forming ATP … in bucket loads.
This motor is incredibly high-tech design in nano-size.

Evolutionary scientists have suggested that the head portion of ATP synthase evolved from a class of proteins used to unwind DNA during DNA replication.

Q: how could ATP synthase “evolve” from something that needs ATP, manufactured by ATP synthase, to function?"
