Introduction to Glycolysis
Living cells can process certain sugar molecules, rearranging their atoms and this process can supply energy to the cell to power growth and other functions. This process is called glycolysis. Glycolysis evolved billions of years ago when there was no oxygen in the earth's atmosphere and it was therefore impossible for cells to gain energy from the oxidation of sugar molecules using oxygen. Later when oxygen was produced as a byproduct of photosynthesis cells evolved to utilise oxygen to oxidise
Formation of Acetyl Co-enzyme A
This page explains the formation of Acetyl Co-enzyme A which is key to the synthesis of many organic molecules in cells. An acetyl group is a simple two-carbon-atom molecule which is sufficiently reactive to make it possible to use as a building block for larger carbon skeletons. A large number of molecules that are synthesised in cells are built from two-carbon acetyl groups. An acetyl group derives from ethanoate (acetate) and is named acetyl when it forms a group within a larger molecule. I
Medicine Games: Control of the Cell Cycle
Play a game and find out about a Nobel Prize awarded discovery or work! In this game you are to take on the job as a Cell Division Supervisor. Are you familiar with the different phases in the cell cycle? If not, maybe you should pay extra attention to the image of the cell cycle in the introduction.
Medicine Games: Incredible Megacell Game
Play a game and find out about a Nobel Prize awarded discovery or work! The compartments of the cell, the organelles, are so small that it was impossible to study their structure until the electron microscope became available in 1938. Albert Claude, Christian de Duve and George E. Palade were awarded ...
Engineering Nanomedical Systems
This course will cover the basic concepts of design of integrated nanomedical systems for diagnostics and therapeutics. Topics to be covered include: why nanomedical approaches are needed, cell targeting strategies, choice of core nanomaterials, technologies for testing composition and structure of ...
Semiconductor device technology has transformed our world by making possible supercomputers, personal computers, cell phones, ipods, and much more that we now take for granted. Moore's Law observes that the number of transistors (the basic building blocks of electronic systems) per electronic chip doubles ...
"Global Enterprise for Micro-Mechanics and Molecular Medicine (GEM4), Summer 2006"
"GEM4 VisionGEM4 has brought together researchers and professionals in major institutions across the globe with distinctly different, but complementary, expertise and facilities to address significant problems at the intersections of select topics of engineering, life sciences, technology, medicine and public health.GEM4 creates new models for interactions across scientific disciplinary boundaries whereby problems spanning the range of fundamental science to clinical studies and public health ca
Red Tide Activities
Welcome to Making Waves, a multimedia approach to learning that offers teachers and students an insider's view of current, relevant ocean science research efforts. This University of South Florida web site contains links to the article "Tiny Toxic Terrors: Harmful Algal Blooms" and four computer-based activities that teach students about various aspects of red tide. Activities include: "Where could they be?," "Is it a plant or animal cell?," "What is bioluminescence?," and "How does plankton sha
Musical Instruments: Wil Blades
Spark visits organ player Wil Blades as he jams with Dr. Lonnie Smith at San Francisco's Boom Boom Room. This Educator Guide is about jazz, the history of the Hammond B3 organ, and the science of electronic instruments.
Microscope Imaging Station
This site shows what blood is, what happens when the immune system goes awry, what are stem cells are, and more. See videos exploring cell structure and function, cell development and motility, plankton, plants, and protozoa. Learn how the sea urchin helps us understand genes, reproduction, and cancer.
Sister Chromatid Differentiation and Exchange in Chinese Hamster Ovary Cells in Culture
This laboratory exercise is designed to illustrate the semi-conservative mode of DNA duplication through the expression of sister chromatid differentiation (SCD), the single-stranded nature of the eukaryotic chromosome organization, and the mutagenic effects of certain chemical or physical agents through induced sister chromatid exchange (SCE). Through individual work and/or a group project, students will learn the basic cell culturing and cytogenetic techniques for chromosome studies, especiall
The Immune System: Red Cell Agglutination in Non-Humans
This exercise presents the concepts of immunology from biochemical, evolutionary, and adaptive standpoints. While all organisms have developed some mechanism of defense against external agents, vertebrates have the most complex immune responses capable of exquisite specificity and long duration. This affords a distinct advantage to species with a relatively long life span and low fecundity. This exercise explores the relationship between immunologic stimulation of the host with foreign antigens
The Power of Genetics: Using Classical and Molecular Genetics to Study "Real" Developmental Phenomen
The goal of this laboratory exercise is to provide a laboratory experience for undergraduates, in which they apply fundamental genetic principles to the study of a complex developmental process, specifically, root cell shape determination in the simple plant Arabidopsis thaliana. In this exercise, students identify putative root cell shape mutants, analyze an F2 segregating population, and finally use molecular techniques to determine where a specific mutation in located within the genome. This
The Study of Development Using Red Algae
This exercise can be used to demonstrate developmental processes at the cellular level, environmental control of photosynthesis, and cell enlargement by using red algae, which is well-suited for these types of experiments.
The Use of Lectins Agglutinins to Study Cell Surfaces
Using lectins, proteins which combine specifically with carbohydrate molecules or groups, this activity will introduce the students to the many important roles that the cell membrane serves in biological processes.
Water and Solute Movement Through Red Blood Cell Membranes
This resource is a detailed laboratory exercise suitable for undergraduate laboratory courses in biochemistry, physiology and cell biology. It includes detailed background information and student outlines, instructors notes, and suggested anaylses.
Orchestrating cell separation in plants: What are the risks and benefits?
In this podcast, Professor Roberts from the School of Biosciences discusses his research into the mechanism responsible for regulating cell separation in plants. In particular how plants 'shed' parts of themselves such as leaves or fruit. Professor Roberts explores the potential application of his research, through prevention or encouraging of the 'shedding' process, agricultural harvests could potentially be increased or even synchronised. Professor Roberts also discusses the resistance faced
The anatomy cookbook: A dissection guide with recipes
The Anatomy Cookbook has been written to accompany an anatomy and physiology course for bioengineers who would otherwise have missed out on the opportunity to study real organ systems at first hand. It is not an alternative to a standard anatomy text, it acts more as a laboratory supplement. The fun bit is that your kitchen takes the place of the dissection room. Each recipe provides an insight into one or more organs, and all you need to do is go to the supermarket and be prepared to think abou
