Chapter 1: Polynomials

Definition: A polynomial is an algebraic expression that is a sum of terms, where each term contains only variables with whole number exponents and integer coefficients Example: The following expressions are all considered polynomials:             X When we write a polynomial we follow the convention that says we write the terms […]

Chapitre 2 : Bioenergetique

                                Introduction à la bioénergétique La respiration cellulaire est composée de trois composantes: 1. Les réactions d’oxydoréduction (oxydo-réduction) 2. La chaîne respiratoire 3. La glycolyse En fait les cellules vivantes ont besoin d’énergie provenant de sources externes. Certains animaux obtiennent […]

Chapter 7 : Photosynthesis

                                 Photosynthesis Photosynthesis is the process that converts solar energy to chemical energy. Directly or indirectly, photosynthesis nourishes almost the entire living worlds -Autotrophs sustain themselves without eating anything derived from other organisms -Autotrophs are the producers of the biosphere, producing […]

Chapter 6 : cellular energy production

                                        AEROBIC WAY The citric acid cycle completes the energy yielding oxidation of organic molecules. In the presence of O2, pyruvate enters the mitochondrion. Before the citric acid cycle can begin, pyruvate must be converted to […]

Chapter 5 : bioenergetics

                         Introduction to bioenergetics Cellular respiration is composed of three topics: Redox reactions (oxidation-reduction) Electron transport chain Glycolysis In fact living cells require energy from outside sources. Some animals obtain energy by eating plants and some others feed on other organisms that eat plants, and […]
