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. Below there is a succinct explanation of Michaelis Menten equation. http://varunyilunusabowebsite.weebly.com/uploads/3/7/5/4/37541075/michaelis_menten_equation.pdf

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. http://www.chembio.uoguelph.ca/educmat/chm356/3560l9.pdf
A very useful guide for statistical analysis and graphical representation of data can be found below. http://www.radford.edu/~jkell/labs103.htm
The Kingdom Plantae represents an extremely large group of mostly terrestrial organisms that are photosynthetic. Below you will find a handout about plants. https://www.msu.edu/course/lbs/158h/manual/Plantae.pdf.
Phytochromes are important pigments for plant growth and flowering. Below you will find a concise outline of the mechanism of action and effects of phytochromes. http://faculty.caes.uga.edu/pthomas/hort4050.web/Hort4050web/Phytochrome%20lecture.ppt
An important technique used in ecology is mark recapture method. www.radford.edu/~jkell/mark_rec103.pdf
There is a number of different mating systems among animals. Some animals tend to be monogamous, others are polygamous. In the outline below you will learn the similarities and differences between mating systems. http://web.pdx.edu/~zelickr/animal-behavior/lecture-outlines/lectures2013winter/LS13-ch11-mating-systems-1.pdf
Drosophila has always been a role model in research, therefore it is useful to know the basics of its anatomy, physiology, genetics, and more. http://home.sandiego.edu/~cloer/bio376f08/376f08_lectures/Lect12-14-376F08(Drosophila).pdf

Here you will find a quick review of plants: from tracheophytes to angiosperms. http://www.eebweb.arizona.edu/faculty/huxman/Huxman_lecture6.2008.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. 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. http://biochemistry2.ucsf.edu/programs/ptf/prologue%20links/Diff%20&%20Trans%20Membranes.pdf
Plant stems are one of the major organs required for long-distance transport of water and biomolecules. In the outline below you will learn about different types and features of stems. ppongam-irsc.weebly.com/uploads/1/9/9/0/19902363/ch04_lecture.ppt
Amino acids are important biomolecules in living organisms, thus it is important to know how amino acids are recycled. https://www.tamu.edu/faculty/bmiles/lectures/amcat.pdf https://www.rose-hulman.edu/~brandt/Chem330/Amino_acid_breakdown.pdf
In a vascular plant, the stele is the central part of the root or stem containing the tissues derived from the procambium. These include vascular tissue, in some cases ground tissue (pith) and a pericycle, which, if present, defines the outermost boundary of the stele. In other words, vascular bundle or the stele consists of three tissues: the pericycle, the …
