Anastasy [175]

Answer:

Biochemistry.

Explanation:

Biochemistry can be defined as the branch of science that deals with the study of the chemical processes, physio-chemical reactions and various substances that are found in living organisms such as animals, plants, and microorganisms.

Simply stated, biochemistry is a field in science that combines both the elements of biology and chemistry in order to study living organisms.

For example, all living organisms have the ability to engage in respiration in other to breathe in oxygen to stay alive. Thus, biochemistry helps us to understand respiration as a physio-chemical process that converts glucose into a form of energy (Adenosine Triphosphate-ATP) that is beneficial to all living organisms.

Hence, the chemistry of living things and living systems created a new combined field in science known as biochemistry.
