Enzymes Proteins- Enzymes belong to the macromolecule group of proteins and can be described as a specialized type of protein. Enzymes are considered the catalysts of life (catalysts=agents that speed up chemical reactions) - Enzymes are named by what they are acting upon and replacing the ending with ?ase? Ex= cellulose to cellulase Enzymes assist in the process of metabolism= the many chemical reactions that occur in organisms. Many chemical reactions would not occur without enzymes because the molecules in cells would simply not house enough energy/contain enough heat, to begin a reaction and carry it out quick enough. An enzymes job is to lower the activation energy needed in a chemical process and to finish by completing it.

Gavin Morgan 10/28/2015 Chapter 6 2-Point Notes Energy can take many forms: 1. Energy is defined as the capacity to do work. 2. Energy can take many forms: mechanical energy, heat, sound, electric current, light, or radioactivity. The sun provides energy for living organisms: 1. Energy flows into the biological world from the Sun. 2. Breaking the bonds between atoms requires energy. Oxidation-reduction reactions transfer electrons while bonds are made or broken: 1. During a chemical reaction, the energy stored in chemical bonds may be used to make new bonds.

Enzyme catalysis 1 ENZYME CATALYSIS By (Student?s Name) Course Instructor Institution City, State Date One of the primary tasks of a protein is to act as an enzyme. Fundamentally, Enzymes are organic catalysts that speed up the rate of virtually all biochemical reactions that occur in a cell. Ordinarily, cellular chemical reactions proceed so gradually that they would not occur under normal organism?s conditions of temperature and pressure (Enzyme Catalysis, 2015). Concisely, enzymatically catalyzed reactions involve the provision of an alternative route alongside stabilizing intermediates. In turn, this causes a reduction in the energy required to reach the highest energy transition state of the reaction as shown below (Enzyme Catalysis, 2015).

Campbell's Biology, 9e (Reece et al.) Chapter 8 An Introduction to Metabolism This chapter lays the foundations for the chapters on respiration and photosynthesis. Key concepts are as follows: The laws of thermodynamics govern energy transformations by living organisms, metabolic reactions couple energy-harvesting reactions to reactions that accomplish cellular work, and enzymes increase the rates of reaction. Understanding the properties of enzymes, how they work, and how their activities are regulated is necessary to achieve an understanding of metabolic pathways. Multiple-Choice Questions 1) Which term most precisely describes the cellular process of breaking down large molecules into smaller ones? A) catalysis B) metabolism C) anabolism D) dehydration E) catabolism
