Enzymes are proteins which are manufactured by the human body during the process of protein synthesis. They are catalysts that drive every chemical reaction taking place in the human body, and they enable the human body to be built from proteins, carbohydrates, and fats. Enzymes are highly specific in their activity and form an enzyme-substrate complex speeding up processes as they lower the activation energy during a given reaction period. Through genetic engineering and by isolating specific enzymes, it has become possible to harness the power of enzymes.

Explains the scientific concepts of photosynthesis, respiration, and enzymes. Laboratory experiments demonstrate: the rate of photosynthesis in greenhouse plants; the amount of oxygen used by the body during respiration at varying speeds; and the reaction times of different enzymes.
Part of the "Visualizing Cell Processes" series. Includes the following modules: "Mitosis: Chromosome Condensation," "Mitosis: Stages," "Cytokinesis," "Meiosis," "Nucleotide Structure and Bonding," "Replication Enzymes," "Replicating the Strands," "The Twisting Problem," and "Proofreading and Repair."
Part of the "Inside the Living Cell" series. Shows how DNA replicates; how copy errors occur and are subsequently corrected by repair enzymes; and how DNA is compressed into chromosomes, making mitosis and cell division possible. Provides an overview of DNA structure, replicating DNA, mutations that change the genetic code, proofreading and repair, and the stages of mitosis.
With support from the National Science Foundation, chemist Kent Kirshenbaum and his team at New York University are engineering molecules to mimic the shapes, structures, and functions of natural proteins. The ultimate goal of this biomimetic chemistry research is to develop a reliable way to build synthetic proteins that can be put to work at the industrial scale. Part of the "Science Nation" series.
Part of the "Inside the Living Cell" series. Illustrates how genetic instructions carried on DNA are transcribed into RNA, leading to the production of specific enzymes that control the thousands of biochemical processes occurring in living cells. Provides an overview of the protein basis of life, enzymatic reactions, amino acids and DNA, how proteins are built, and gene activation.
