Enzyme Lab Introduction/ Abstract An enzyme is a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. They are mainly made up of proteins and can tremendously speed up reactions. E. coli ( a bacterium) has about 1‚000 different types of enzymes floating around in its cytoplasm at any given time. Enzymes can be used to join and even break up molecules as shown in the diagram below. (1)

Misael Acosta Photosynthesis Lab Report Ms. Rocha AP Biology 4th Period II. Intro/Background 1. In order for oxygen to be present photosynthesis must occur. Photosynthesis takes in light and CO2‚ and through a series of steps produces oxygen. Photosynthesis can be measured by either the disappearance of substrate or the accumulation of product. Examples include the production of O2 or the consumption of CO2. All the oxygen within the leaf disks will be removed before being placed

AP Biology Summer Summaries There are many differences between proximate and evolutionary causes and explanations on why we are such easy targets for diseases. The proximate explanations are described by its anatomy‚ physiology‚ and biochemistry. Evolutionary explanations go into detail on what would happen if we didn’t have the genes that cause us to get sick. Proximate causes look for what genes it is made up of and how it works. Evolutionary causes are why natural selection hasn’t eliminated

AP: CHAPTER 43: IMMUNE SYSTEM 1. List the two lines of nonspecific defense mechanisms with examples of each. • External defense‚ which includes the skin and mucous membranes in the body. • Internal defense which includes phagocytic cells and antimicrobial proteins. 2. What is meant by specific defense? Defense mechanisms are said to be specific because depending on which one they focus on one specific part of the body or a specific type of pathogen. 3. Give examples of “barrier defense
