CELL ANATOMY Microbodies Brief History Microbodies were first discovered and named in 1954 by Rhodin. De Duve chose the name of Peroxisome because of its relationship with hydrogen peroxide. In 1967‚ Breidenbach and Beevers were the first to isolate microbodies from plants‚ which they named Glyoxysomes because they were found to contain enzymes of the Glyoxylate cycle.

Hello everyone! I hope you had a wonderful weekend. We are going to start class today talking about cells. Believe it or not‚ each and every one of you came in contact with cells over the weekend. The most important thing to remember is this: cells make up living things. They make up us‚ our families‚ our dogs‚ and even the trees that provide shade to your front yard. Today we are going to focus on the cells that make up our bodies. Your skin‚ brain‚ muscles‚ bones‚ and every other part of your body

Eukaryotic & Prokaryotic Cells Introduction: The Cell: The cell is a functional unit of all living organisms. Cells have evolved into two fundamentally different types‚ eukaryotic and prokaryotic‚ which can be distinguished on the basis of their structure and the complexity of their organization. The simplest organisms which consist of one cell are called prokaryotes. More complex organisms are called eukaryotes and they consist of many cells. Objectives: * Define the terms: Eukaryotes

contemporary biological issue Introduction Stem cells are undifferentiated cells able to differentiate into specialized cell types. These are used for stem cell treatment‚ which is an intervention strategy that introduces new adult stem cells into damaged tissue in order to treat disease or injury. For over 30 years‚ bone marrow and‚ more recently‚ umbilical cord blood stem cells have been used to treat cancer patients with leukaemia and lymphoma because during chemotherapy most growing cells are killed‚ but a donor’s

renewable energy sources‚ fuel cell technology has received great attention as an alternative to the conventional way of getting energy due to its high efficiency‚ clean operation and cost efficient supply of power demanded by the consumers. Proton exchange membrane (PEM) fuel cells technology plays a leading role for many applications when comparing with other competitive types of fuel cells. The world is in high demand for clean alternative fuel source and PEM fuel cells could be that change with a

Determination of an Electrochemical Series In electrochemistry‚ a voltaic cell is a specially prepared system in which an oxidation-reduction reaction occurs spontaneously. This spontaneous reaction produces an easily measured electrical potential which has a positive value. Voltaic cells have a variety of uses and you commonly refer to them as a “battery”. Half-cells are normally produced by placing a piece of metal into a solution containing a cation of the metal (e.g.‚ Cu metal in a solution

TOPIC 3.7 + 8.1: CELL RESPIRATION 3.7.1 Define cell respiration. Cell respiration is the controlled release of energy from organic compounds in cells to form ATP (adenosine triphosphates). 3.7.2 State that‚ in cell respiration‚ glucose in the cytoplasm is broken down by glycolysis into pyruvate‚ with a small yield of ATP. Glycolysis in cytoplasm: Glucose 2 pyruvates + small amount of ATP (does not use oxygen) 3.7.3 Explain that‚ during anaerobic cell respiration‚ pyruvate can be
