At present, studies on the relationship between protein dynamics and protein function are focusing on the relationship between protein dynamics and enzyme .
What you have is the collision of two molecules of nitric oxide that results in the breakage of nitrogen-oxygen bonds and the creation of new nitrogen-nitrogen and oxygen-oxygen bonds. Figure showing two molecules of nitric oxide gas colliding to form a molecule of nitrogen gas and a molecule of oxygen gas If we were to dump a whole bunch of nitric oxide molecules into a normal jar with no catalytic converterand we were able to get an extreme close-up of what was going on at the molecular level, we would see millions of N-O molecules spinning and tumbling in space, smashing into each other and ricocheting off the walls of the jar at incredible speeds.
Very, very few nitrogen or oxygen molecules would be created, whereas most ofthe nitric oxide molecules would just bounce off of each other.
Why the nitric oxide molecules bounce off each other: You also know that if you try and align one pole of a magnet with the same pole of the other, the magnets will repel.
Nitrogen and oxygen atoms are like magnets in this sense.Proteins & Enzymes (regular biology) updated
Figure showing magnets attracting and repelling and a figure a nitrogen and oxygen atom attracting and repelling. The first rule is that there is a mutual attraction between red magnets and blue magnets. This means that if you stick the north pole of a red magnet to the south pole of a blue magnet, they will stick together, just like you would expect with two magnets.
The second rule is that there is a stronger mutual attraction between magnets of the same color: What this means is that a red magnet will prefer to stick to another red magnet, and a blue magnet will prefer to stick to another blue magnet, if given the choice.
So those are the rules about how our magnets behave. If the poles of the colliding magnets are lined up in the correct way, so that the north pole of one red magnet is contacting the south pole of the other red magnet, with the same happening for the blue magnets, what would happen?
But only if the alignment is correct! Figure of nitrogen and oxygen atoms colliding then bonding. This magnet thought experiment is a good approximation of what happens with real-life molecules like nitric oxide.
But the alignment is key--nothing will happen without it. This is where catalysts come in. They help with alignment. The odds favor nothing happening. This is what happens with nitric oxide molecules in a jar, when no catalyst is present. Figure of nitric oxide molecules in a jar unable to correctly align. But now imagine that we add an extremely motivated and conscientious magic gnome to the inside of our jar, with the instructions that he is to grab a red-blue in each one of his hands, align them in the right way, and then smash them together.
Adding this helpful gnome assistant will increase the rate at which red-reds and blue-blues are made, because achieving the right alignment is no longer a matter of random chance.

A platinum screen sits inside a catalytic converter attracting nitric oxide molecules to it and aligning them in just the right way, so that when they collide, the N and O switch places, and nitrogen gas and oxygen gas are created. Catalysts make reactions fast by aligning reactants so that successful reactions are more likely!
Enzymes are biological catalysts Enzymes are the catalysts involved in biological chemical reactions. Why enzymes are so important The big reason enzymes are important to life is because cellular energy is a precious resource. This increase in the total number of collisions per second would increase, just as a matter of probability, the number of correctly aligned collisions too.
So, in the end, shaking the jar harder much harder, perhaps would result in an increase in the speed of red-red and blue-blue production too, just like adding a gnome and keeping the shaking of the jar the same. Figure of nitric oxide molecules in a shaking jar correctly and incorrectly aligning.
By just shaking the jar harder, you choose to do the work yourself and forego the services of the gnome. You get the same end-result, but it requires more energy expenditure on your part. If you use the gnome, you get to save this energy for other purposes: Or what if you have lots of energy available, but you have to do a lot of work to obtain it? Or, maybe you have extra energy, but you want to spend it on doing other important things. In any of these three cases, the added savings you get from using the gnome to do the work might make a world of difference.
Pretty cool for a few minutes effort! Consider a rabbit in a field. This rabbit has millions and millions of cells, all of which have billions and billions of chemical reactions going on, every second of every day that the rabbit is alive.

Amino acid is the basic structural and functional unit of these macromolecules. An amino acid molecule is composed of four basic groups; namely, amino group, side chain R- groupcarboxyl group, and hydrogen atom, which are bonded to a central carbon atom. Basically there are twenty naturally occurring amino acids, and they differ only by the side chain R-group. The order of amino acids determines the structure and functions of protein and enzymes.
Enzymes Enzymes are the special three-dimensional globular proteins that can act as biological molecules, to catalyze and regulate chemical reactions in organisms. In a single cell, there are thousands of different enzymes. That is because almost every reaction in a cell requires its own specific enzyme. Normally enzymes cause cellular reactions to occur million times faster than corresponding uncatalyzed reactions.
The active sites present on the surface of enzyme determine their degree of specificity. Types of enzyme specificity include absolute specificity, stereochemical specificity, group specificity, and linkage specificity.
Active sites are the cracks or hollows on an enzyme surface caused by the formation of tertiary structure. Some active sites bind only one particular compound, while others can bind group of closely related compounds.
