Life cycle patterns

admin Theory

Hi, Let’s review some points about organisms’ life cycles. A life cycle is a series of changes in form that an organism undergoes, returning to the starting state. Transitions of form may involve growth, asexual reproduction, and/or sexual reproduction. More about life cycles can be found HERE. https://www.cabrillo.edu/~ncrane/bio1c/botPDFs/Labs/bacteria,%20cells,%20protists,%20lifecycles/Life%20Cycle%20Patterns.pdf http://waynesword.palomar.edu/lmexer8.htm http://en.wikipedia.org/wiki/Biological_life_cycle

Introduction to mycology

Hi, Only a few of us pay attention to one of the most abundant organisms on the planet – fungi. In national olympiads you quite often can find tasks about fungi, however, in the IBO you may be asked to classify them or choose right answers from multiple choice about they properties as well as reproduction mechanisms and structures. To …

Glycolysis overview

admin Theory

Hello, Let me introduce by far the most important metabolic process of all cells -glycolysis. Glycolysis is the metabolic pathway that converts glucose C6H12O6, into pyruvate, CH3COCOO− + H+. The free energy released in this process is used to form the high-energy compounds ATP and NADH.The glycolysis pathway can be separated into two phases:     The Preparatory Phase – in …

Hi there, If SDS PAGE sounds like a ridiculous combination of letters, you urgently need to decipher what these letter mean and understand the mechanism of this technique. Firstly, watch the video. Then flick through the notes. http://web.mnstate.edu/provost/BiochemistryLabI.html http://en.wikipedia.org/wiki/Polyacrylamide_gel_electrophoresis A good tutorial about gel electrophoresis can be found HERE.  

Protein Purification Tutorial

admin Developing practical skills

Hey, During the IBO practical you may be asked to perform a protein purification and then make some calculations. Thus, let’s introduce yourself to protein purification. Firstly, read the notes. http://web.mnstate.edu/provost/BiochemistryLabI.html Then watch a video to visualize how this process appears in a lab.
