Answer: In chemical reactions enzymes lower the activation energy for a reaction. That being said they decrease energy required for a reaction to occur but they don’t necessarily increase the rate at which the reaction occurs.
So probably C but if you’re still unsure you might want a second are in this case third opinion.
The linear sequence of amino acids within a protein is considered the primary structure of the protein. Proteins are built from a set of only twenty amino acids, each of which has a unique side chain. The side chains of amino acids have different chemistries.
<span>The experimental evidence that leads </span><span>scientists to believe that only quantized electronic energy states exist in atoms </span>was the Niels Bohr experiment on Hydrogen gas. The quantized model for electron orbits in atoms that effectively explained the spectroscopic behavior of the atoms. Each line in the spectrum corresponds to one exact frequency of light emitted by the atom.
