Enzyme
Enzymes
-
the combination and other properties dictate the environment of the activate site, and hence there are specific enzymes for each substrate (think of jigsaw puzzle pieces)
Substrates
-
could be multiple substrates in a reaction, or also one substrate could break down into multiple products
basically, structure of enzymes determines which substrates can bind to it
-
when combine, form enzyme-substrate complex, which lowers activation energy and increases rate of reaction
-
ATP
functions
-
-
molecule as the cells' primary energy currency in much the same way that money is the currency that people exchange for things they need.
-
within some of its bonds, it contains the potential for a quick burst of energy that can be harnessed to perform cellular work.
Structure
The three phosphate groups, in order of closest to furthest from the ribose sugar, are alpha, beta, and gamma.
Adenosine is a nucleoside consisting of the nitrogenous base adenine and a five-carbon sugar, ribose.
-
Both bonds that link the phosphates are equally high-energy bonds (phosphoanhydride bonds) that, when broken, release sufficient energy to power a variety of cellular reactions and processes.
These high-energy bonds are the bonds between the second and third (or beta and gamma) phosphate groups and between the first and second phosphate groups.
These bonds are “high-energy” because the products of such bond breaking—adenosine diphosphate (ADP) and one inorganic phosphate group (Pi)—have considerably lower free energy than the reactants: ATP and a water molecule
ATP is a highly unstable molecule. Unless quickly used to perform work, ATP spontaneously dissociates into ADP + Pi, and the free energy released during this process is lost as heat.
Catalyst
a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change
A substance that helps a chemical reaction to occur is a catalyst, and the special molecules that catalyze biochemical reactions are enzymes.
