Some base pairs have 2 hydrogen bonds, but others have 3. So if one ATP molecule is always consumed to break a base pair, is energy wasted when helicase uses it for a 2-bond base pair?
I think the ATP is used to power the mechanical movement of the helicase, not so much to the breaking of base pairs individually or specifically, so I'd say... No?

How in the *actual hell* did they figure out this ? It's not like they could see molecules under microscope......oh wait...isotope labelling ? Is that it or are there any other methods ? Plz help, I'm super excited about this Thank you
There are many other methods, actually. There's Electron Microscopy, Electron Crystalography, X-ray Crystalography, Neutron Diffraction, Nuclear Magnetic Resonance...

Since air carries sound, and is also made of molecules, their shaking is at too small a scale to disturb the air. But it does disturb photons, which get bounced out in the form of heat energy. In fact, that's what ATP excels at
@@prototype2889 That's a very dismissive and lazy way of answering a simple question, and a wasted opportunity to elevate somebody's curiosity. For a person who seems interested in science, this attitude is not very effective nor constructive. Are you OK?
yeah its a mind boggling/ impossible concept both ways... though it would be more easy if things didnt need to follow physics or any laws eg a cube planet or dna just magically copies itself without any chemical influence... would make the case of non abiogenesis more... with this vid, its easy to continue it and just need certain chemicals to create chain reactions and increase in complexity through adding/ bumping into other chemicals, as we are all made of chemicals just like all the other 'dead'/not alive things in the universe. its a mystery to solve.
You mean "much easier" of course. What you are viewing here is nothing but physics and chemistry at the molecular level. Once you understand it's nothing but chemicals and physics, and that the individual molecular interactions are very simple, but very reliable, and totally relentless, provided you are not denied air for three minutes, water for three days, or food for three weeks! The food you eat is used to create ATP, which powers practically all your cells' internal processes. Chemicals react according to physics. And now you have seen the incredible rate at which chemistry takes place inside every cell in your body. Helicase, for example, when it unzips a DNA strand spins the DNA at 10,000 rpm - or about as fast as a jet engine! With chamistry happening at this speed, in trillions of quadrillions of locations on Earth, over billions of years, it is easier to understand how evolutionary forces create complex life. Bad chemistry inside a cell almost immediately kills it. So, failures in reproduction which do not lead to a reproducing lifeform, is the driving force of evolution.
@@Chris.Davies I still cannot grapple with the "nothing but physics and chemistry" part. Now yes I agree that is what we see now. But to think that all this complexity and systems on top of systems of even simple molecular interactions as you put it, coming and immerging out of nothing is close to magic for me, even with a dash of eons of time added. There has to be something underlying, something we are missing

To be able to physically see the molecular machines that exist within every one of our trillions of cells is truly awe-inspiring.

I knew about ATP and DNA helicase enzymes, but I had never seen how helicase is powered by ATP. Phenomenal animation, thank you.
Every time I watch these molecular machine videos I have an existential crisis

But after that I proceed to watch some memes and everything's back to normal lol

I can watch these animations forever.
Amazing work as always! Absolutely love the audio/sound effects!
Unbelievable this process happens in everyone of our Cells....i enjoy ur wee movies 🎬 so much

The way is simple as circle - just use energy to get more energy
It is pretty incredible, the closer you look the more it looks that way 😅
Well, they're not really "impossibly* reliable". Where do you think those genetic diseases come from?
Thanks
Yeah, great animation. Great illustration. Molecules inside the body are so busy. Any slower animation? I can not even see what they do .
I think you can slow the video down using the setting control on the bottom right - looks like a gear or wheel.
