Final answer:
Biochemical assays in biology measure components such as proteins, metabolites, and enzymes. They can detect changes in color to measure protein concentration and identify microorganisms based on their biochemical reactions.
Step-by-step explanation:
In biology, biochemical assays are used to measure various components in a sample, such as proteins, metabolites, and enzymes. For example, a biochemical assay can measure the concentration of proteins in a sample by detecting changes in color that indicate the amount of protein present. Another example is the use of biochemical assays to identify microorganisms based on their biochemical reactions and metabolic tests.
