Origin of biochemistry
Explanation
Biochemistry is the field of science that explores the molecules and processes that occur in living things. The term biochemistry comes from adding bio-, or "life," to chemistry, which is the science that deals with the composition, structures, and properties of substances, along with the reactions and transformations they undergo in combination. Looking at the human body through the lens of biochemistry can help us understand processes like digestion and nutrition. Proteins, carbohydrates, and other nutrients are all chemicals — and it's thanks to biochemical reactions that your body's cells are able to absorb glucose and create energy to keep you going.
