All the organism's chemical processes, comprising anabolic and catabolic pathways.
1 of 10
Metabolic pathway
A sequence of enzyme-controlled reactions in which a product of one reaction is a reactant in the next.
2 of 10
Enzyme
A biological catalyst; a protein made by cells thaat alters the rate of a chemical reaction without being used up by the reaction.
3 of 10
Catalyst
A molecule which speeds up a chemical reaction, but remains unchanged at the end of the reaction.
4 of 10
Active site
The specific there-dimensional site on an enzyme molecul to which the substrate binds by weak chemical bonds.
5 of 10
Enzyme-substrate complex
Intermediate structure formed during an enzyme-catalysed reaction in which the substrate and the enzyme bind temporarily, such that the substrates are close enough to react.
6 of 10
Activation energy
The minimum energy that mcut be put into a chemical system for a reaction to occur.
7 of 10
Denatured
An enzyme's active site is permanently distorted by the irreversible breaking of hydrogen bonds, preventing substrate binding and reducing the rate of reaction.
8 of 10
Inactivation
Reversible reduction of enzyme activity at low temperature as molecules have insufficient kinetic energy to form enzyme-substrate complexes.
