Period 1 10/14/12 Enzyme lab Enzymes are biological catalysts that speed up the process of chemical reactions. They are also proteins‚ and most enzymes activities occur within organism. They decrease activation energy‚ energy that is needed to start a chemical reaction. Enzymes are substrate specific substrates ending in "-ase"‚ enzymes ending in "-ase". External factors‚ such as temperature‚ pH‚ and concentration of the substrate‚ affect the enzymes activity in the lab‚ pectase and cellulase will

Medicine and Disease Study Questions 1-10 1. Describe the role of the macrophage in the immune response. They are known as the vulture cells randomly engulf and destroy bacteria‚ cell debris or foreign matter. 2. State the origin and purpose of lymphocytes. The immune cells‚ or lymphocytes as well as macrophages provide the specific mechanism for the identification and removal of foreign material. Natural killer cells are lymphocytes distinct from the T and B lymphocytes. They destroy

Formal lab report: Abstarct: The Purpose of this experiment was to perform Agrobacterium-mediated transformation in Wild type Arabidopsis thaliana Columbia by using somatic plant transformation method. The whole process lasted for over a period of 11 weeks and we were successful in getting transformed plants. Agrobacterium tumefaciens strain containing pMP90 (Ti-helper) plasmid and pCAMBIA1391 (T-DNA) plasmid was used for this plant transformation. pCAMBIA1391 plasmid was constructed by cloning Brassica

depression and immune response. Depression has been implicated in causing behavioral changes in people with major depressive disorder. Some of these lifestyle changes can be profound‚ such as‚ not eating‚ drug abuse‚ or disturbed sleep patterns. Some argue that it really is these "lifestyles" which is the culprit in reduced immune functioning. Having bad nutritional habits could starve the body of necessary nutrients to maintain high levels of white blood cells. As a result‚ the immune system downgrades

The Effects of Environmental Stimuli on Animal Behavior AP Biology Emily Olsen April 26‚ 2012 I. Introduction: The purpose of this lab is to test the effect certain stimuli has on the behavior of a terrestrial isopod. These bugs are more commonly known as pill bugs and potato bugs. The objective of this experiment is to determine which kinds of habitats potato bugs favor. Potato bugs have an innate behavior called taxis which will cause the animal to move away from a stimulus that is unwanted

food molecules and oxygen. Chloroplast 2. This organelle is constructed of cellulose and supports plant cells and prevents them from blowing up. Cellulos 3. This organelle contains enzymes for intracellular hydrolysis of food molecules. Lysosom 4. This organelle takes in food molecules and oxygen and can transfer the food energy to ATP batteries‚ which will eventually collision energy for chemical reactions. Products of these events are carbon dioxide and water. Mitocondria 5. These organelles

species used to assess pollution levels in the environment? Indicator species are particular aquatic invertebrates that alert us to pollution problems in an environment. Indicator species are used to assess pollution because they change rapidly in response to changes in ecological variables‚ such as food availability‚ water temperature‚ amount of dissolved oxygen in the water‚ pH levels‚ and other factors. Suppose you are an ecologist studying the effects of acid precipitation on plant life. Describe
