the basic mechanisms by which enzymes increase the rates of chemical reactions can be classified into four groups. What are they?

Solutions

Expert Solution

1) Facilitation of proximity or propinquity effect - substrates are brought to close proximity at the active site of the enzyme

2) Covalent catalysis - A covalent bond is formed between the substrate and the enzyme (covalent bond is formed between the nucleophilic aminoacid side chain with the electrophilic center of the substrate) thus forming a reaction intermediate.

3) General Acid- Base catalysis - Acid- Base catalysis involves transfer of proton in the transition state

4) Strain, molecular distortion, shape change - strain in th bond of reactant and release of strain as the transition state gives rise to product

4. Chemical reactions break existing bonds and make new bonds. Enzymes are biological catalysts (proteins) that speed up biological reactions. Just of note, there are only three known biological reactions that can occur at any measurable rate without enzymes – they control everything in biology! Consider the hydrolysis of ATP: ATP + H2O <--> ADP + Pi You know that there are MANY biological reactions that use the energy of ATP hydrolysis to power other reactions. Each of these reactions...
