Charles Darwin was not the first scientist to explain evolution or that species change over time. However, he gets most of the credit simply because he was the first to publish a mechanism for how evolution happened. This mechanism is what he called Natural Selection. As time passed, more and more information about natural selection and its different types were discovered. With the discovery …

An ecological niche is the role and position a species has in its environment; how it meets its needs for food and shelter, how it survives, and how it reproduces. A species’ niche includes all of its interactions with the biotic and abiotic factors of its environment. Biological Niches Big thanks to http://www.montana.edu/screel/Webpages/Bio%20303/Biol%20303%20niches.pdf.
Michaelis Menten equation is used to study the kinetics of enzymatic reaction. Usually, the rate of reaction (a.k.a. velocity) is measured at several different substrate concentration values. Then, a plot of the reaction rate versus the substrate concentration can be used to demonstrate two useful kinetic parameters: Vmax and Km. Vmax is the maximum reaction rate that is observed when …
Enzymes are fundamental molecules for all living organisms that catalyzes almost all reactions. Thus enzyme biochemistry is a very important topic in biology. Below there is a lecture handout about enzymology. Big thanks to http://webmedia.unmc.edu/alliedhealth/CLS/CLS414 08/Enzymes Lecture Handout 08.pdf.
Below you will find a concise description of main principles of thermodynamics and enzyme kinetics. Big thanks to http://ocw.mit.edu/courses/biology/7-014-introductory-biology-spring-2005/readings/l5_bioche_deltag.pdf.
When studying enzyme kinetics, one very important topic is about inhibitors. There three main types of inhibitors: competitive, noncompetitive, mixed. Also you can come across uncompetitive inhibition. Below you will find some figures illustrating the differences between those inhibition patterns.

Glycogen is the most important storage form of glucose in animal body. Thus, it is of paramount importance to understand how glycogen is utilized. Below you will find a concise outline of biochemistry of glycogen which is not covered in Campbell, but you can come across some questions regarding this in olympiads. Big thanks to http://www.chembio.uoguelph.ca/educmat/chm356/3560l9.pdf.
In this tutorial you will learn more about genetic analysis, recombination frequencies and linkage. Big thanks to http://www.webpages.uidaho.edu/biosci/labs/wichman/courses/Biology%20210/2006/Macs/Exam%202mac/Lec9and10RecombMap.pdf.
In olympiads you will encounter glycolysis very often. It is useful to remember the main enzymes, substrates and unique properties of reactions involved in this process. Also do not forget that glycolysis occurs in the cytoplasm, not in mitochondrion. Big thanks to www.csun.edu/~jm77307/Glycolysis.pdf.
In order to successfully function, survive, and reproduce all cells require the ability to transport molecules in and out of the cell. There are two main transport types: active and passive transport. In the outline below you will learn unique characteristics of each.
