Protocol for Lab 5 – Aerobic Respiration Part 1 Isolation of Mitochondria from Cauliflower - Weigh 50g of rosettes cut from fresh cauliflower head. - Cut rosettes and place it on ice - Prepare juice extractor by placing ice and an empty 150 ml beaker into the right compartment. - Collect pulp from left compartment and record total volume of the extract. Approx. 20ml - Filter the pulp using six layered cheese cloth and collect it in a beaker sitting on ice. - Place two 50 ml test tubes

which cells divide and create living creatures. Without meiosis we cannot have the process of mitosis‚ which is the process by which cells of tissue are created for living creatures. When meiosis occurs 4 daughter cells are created‚ while only 2 are created in mitosis. With the creation of 2 daughter cells the new cells will be similar to the parent cell‚ but will have differences‚ as there more parent cells involved. When mitosis occurs the daughter cells will be identical to the parent cell‚ since

Transformation Efficiency is Dependent Upon Plasmid Grant Zarrinmakan‚ Berkley Kruschke‚ Erika Lawrence. Wed/Fri‚ D-Block‚ 12-January-2015 Introduction Transformation is the genetic alteration of a cell resulting from the direct uptake of exogenous DNA from its surroundings. By doing this lab‚ we will answer the essential question: What influences transformation efficiency? Although there are many possible influences‚ our hypothesis is that plasmid has a positive influence. To test this hypothesis

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)

Respiration is all of the physical and chemical processes in an organism by which oxygen is conveyed to tissues‚ cells and the oxidation products carbon dioxide and water given off (dictionary.com). Aerobic respiration is a cellular respiration that requires oxygen too and order to help generate energy. The two processes which are photosynthesis and respiration are

Biology 1010 is a course that introduces students to the basic biological phenomena in all living organisms. It focuses on the different molecular levels of organization‚ heredity in evolution‚ genetics and reproduction. Through this course‚ I was able to master three essential concepts such as Mendel’s Law of Segregation‚ enzymes‚ and photosynthesis. Gregor Mendel was an Augustinian monk that argued that parental traits are passed on to their offspring discrete “heritable factors”. Heritable factors

Biology Lab Scientific Paper Down syndrome is a condition in which a person has an extra chromosome. Chromosomes are small “packages” of genes in the body. They determine how a baby’s body forms during pregnancy and how the baby’s body functions as it grows in the womb and after birth. Usually‚ a baby is born with 46 chromosomes but babies with Down syndrome have an extra copy of one of these chromosomes‚ chromosome 21. A medical term for having an extra copy of a chromosome is trisomy. Down syndrome

Introduction Most organisms produce adenosine triphosphate (ATP) as a source of energy for cellular work‚ using cellular respiration. Cellular respiration is a process that involves glycolysis -breaking down glucose into two molecules of 3- carbon pyruvate‚ the Krebs cycle - oxidizing organic fuel derived from pyruvate-‚ and the electron transport chain - moving electrons through a series of protein complexes to generate ATP (Reece‚ et.al‚ 2011). The process of cellular respiration occurs
