Enzyme kinetics
In biochemistry, enzymes are proteins that act as biological catalysts. Catalysis is the addition of a catalyst to a chemical reaction to speed up the pace of the reaction. Catalysis can be categorized as either homogeneous or heterogeneous, depending on whether the catalysts are distributed in the same phase as that of the reactants. Enzymes are an essential part of the cell because, without them, many organic processes would slow down and thus will affect the processes that are important for cell survival and sustenance.
Regulation of Enzymes
A substance that acts as a catalyst to regulate the reaction rate in the living organism's metabolic pathways without itself getting altered is an enzyme. Most of the biological reactions and metabolic pathways in the living systems are carried out by enzymes. They are specific for their works and work in particular conditions. It maintains the best possible rate of reaction in the most stable state. The enzymes have distinct properties as they can proceed with the reaction in any direction, their particular binding sites, pH specificity, temperature specificity required in very few amounts.

High nitrogen levels reduce HSP production
Heat shock proteins protect plants from stress
HSP 24 levels rapidly increased during the heat shock, with high N plants reaching a higher peak, and with high N plants maintaining higher levels of HSP 24 for a longer period after the heat
There was no effect of nitrogen on the production of HSP 24
The control plants in figure a provided the baselines for figure b
High nitrogen control plants (not heat shocked) had the same HSP 60 levels as controls
In the control plants, the constitutive level of HSP60 was higher (nearly double) in high nitrogen grown plants. There was greater production of HSP60 in high N grown plants than low N grown](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2d2a894b-5d23-4d74-addb-138aa024bb4a%2Fae70412a-2893-4167-a795-706971436404%2Fl1m0r0i_processed.png&w=3840&q=75)
