A biochemist studies the molecules and chemical reactions that take place in all living organisms.

Biochemists use advanced laboratory instruments like electron microscopes and lasers to study the chemical principles of biological processes. Some of the most common areas of study include heredity, metabolism, growth, cell development, nutrition and reproduction. In short, biochemists try to better understand the chemical make-up of life. 

They may look at reactions that turn food into energy, how our DNA makes us look the way we do, and how plants trap and use the energy of sunlight. This area of study has made extensive contributions to the fields of medical DNA analysis, immunology, tissue transplantation, environmental monitoring and many other diverse areas.

In order to work effectively, biochemists need to be able to work well with other people. They normally work in teams with many other biochemists, and often get to work with experts in other disciplines as well. Collaboration with chemists, computer scientists, engineers and physicists is common.
