What kind of biomolecule are enzymes typically composed of? what effect do enzymes have on their substrates and the overall reaction? give at least 4 real life examples!

Enzymes are typically composed of amino acids.

Enzymes specifically binds to their substrate, and accelerate the biological or in-vitro reactions.

Four real-life examples of enzymes are: Lipase, Maltase, DNA ploymerase and Alcohol dehydrogenase.

Explanation:

All enzymes are proteins. They are composed of amino acids as monomer units linked by polypeptide bonds.

The substrate is a molecule which has specific enzyme binding sites for the highly specific enzyme called as active sites. With this binding, the  enzyme-substrate complex is formed, undergoes the chemical reaction and new product is formed. Enzymes accelerate the biological reactions by lowering the reaction's activation energy.

Four-real life examples of enzymes are:

Lipase enzyme: catalyses the hydrolysis of fats and triglycerides in the small intestine. Lipase enzyme is secreted by pancreas.

Maltase enzyme: catalyses the breakdown of maltose sugar. It is secreted by salivary glands and our mouths.

DNA Polymerase Enzyme: It catalyses the DNA replication in the cells. It is secreted by the nucleus

Alcohol dehydrogenase: It catalyses many reactions in the body as the reduction of NAD to NADH. It is secreted by the liver.
