Introduction: Living things go through chemical reactions everyday. A chemical reaction is a process in which one or more substances are chemically changed into one or more new substances. Examples of chemical reactions are as simple as typing on a key board, watching T.V., digesting food, and breathing. Breathing is a chemical reaction because humans take in oxygen which turns the glucose (sugar) into energy which humans need to survive. Enzymes can reverse a chemical reaction. For example, A+B→C. This is a general equation for the building of large molecules. C→A+B is a general equation for the breakdown of large molecules. Enzymes are reversing this chemical reaction. An enzyme is a chemical or catalyst produced by cells to speed up one specific reaction. Enzymes are found in all living things. Enzymes are necessary to all living things on Earth. The substrate is the molecule that the enzyme acts on. Think of it as a lock and key. The enzyme is the lock and the substrate is the key, so they lock together. The part of the enzyme that the substrate bonds to is the active site. The active site is basically where the substrate fits into the enzyme. Two of the many characteristics of enzymes would include that they are not used up in a reaction. That means that the enzymes never run out. Also, enzymes can only catalyze 1 type of reaction. Catalyze means to speed up. Each enzyme has a specific shape that allows it to do its job. In order for enzymes to function properly, they
Unit 1: Cell Biology
Introduction to Cells
Outline: Cell Theory
1. All living things are made of cells which:
are surround by a membrane
contain genetic material
perform enzyme-catalyzed reactions
can harness and use energy to power activities
This was proven by biologists who, through microscopes, were able to see that all living things contained cells, albeit various types.
2. Cells are the smallest unit of life.
Viruses were thought to be living, and thus would make them the smallest unit…
division preparation courses for the major. All
courses must be taken for a letter grade. THIS MAJOR IS HIGHLY SELECTIVE; a
significant number of preparatory courses should be completed prior to transfer.
At minimum, you should complete one year of biology with laboratory, one year of
general chemistry with laboratory, one year of calculus and one semester of
organic chemistry with laboratory. Completion of a second semester of organic
chemistry or one year of calculus-based physics is strongly recommended…

Title: Identification of Two Unknown Bacteria’s Through the Use of Gram Staining
Introduction: The Gram staining of bacteria is a widely used method to identify unknown bacteria. The purpose of this method is to find out identities of unidentified bacteria. By using this tool we can group bacteria into two main groups: Gram-positive and Gram-negative. In our past two labs, we streaked an unknown bacteria using aseptic technique onto two separate petri dishes leading to an isolated community of…

INSTRUCTOR: Jimmy Wedincamp, Ph.D.
COURSE: Biology 1107 and 1108 (Principles of Biology). This course is an introduction to the science of Biology. Topics covered include the chemical and cellular basis of life, the perpetuation of life, and evolutionary biology. Because of the large volume of material covered in this course, it is important that you keep up on a daily basis.
Contemporary Molecular Biology”
Sylvia Culp and Philip Kitcher
Traditional approaches to theory structure and theory change in science do not farewell when confronted with the practice of certain fields of science. We offer an account of contemporary practice in molecular biology designed to address two questions: Is theory change in this area of science gradual or saltatory? What is the relation between molecular biology and the fields of traditional biology? Our main focus is a recent…

Biology, Genetics, and Substance Abuse and Addiction
The relationship between genetics and substance abuse or addiction is a source of some controversy in the field (Walden University, 2014). In this application, I will consider how natural dispositions and genetics may influence substance abuse and addiction and develop a position…
Biodiversity sounds like a scary word, but it is one of the most essential functions an ecosystem must always have in order for species to adapt to new environments and keep moving forward by evolving to be more successful to their environment or environments. This is the way of conservation biology.
