Dna plays a major role in heredity, composing the genes that are passed down from parent to offspring. it also plays a major role in the everyday workings of your cells. it does this by creating molecules, such as enzymes, that regulate cell functions.

these enzymes belong to a larger class of molecules known as
a) rna.
b) proteins.
c) ion pumps.
d) amino acids.

The correct answer will be option-B.

Explanation:

The DNA is the genetic material of the cell which provides instructions to the cells.  They provide instructions to the cell by forming the protein molecules through transcription and translation.

These proteins regulate the basic functions of the cell wither by acting as the structural component or the enzymes. These enzymes act as a catalyst and increase the rate of reaction by lowering down the activation energy of the reaction.

Since enzymes are the protein molecules thus, Option-B is the correct answer.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products

a researcher conducts an experiment on the secretion of a particular hormone in mice. scientists inject mice with a substance that stimulates the production of the hormone. the scientists then test the levels of hormones produced by the mice. the tool used to measure the hormones consistently detects the levels at 10 points lower than the actual hormone levels in the mice. this tool makes measurements, but the measurements aren't .
