Cellular Respiration?An Overview 1 Cellular Respiration?An Overview What are the phases of cellular respiration? Why? All cells need energy all the time, and their primary source of energy is ATP. The methods cells use to make ATP vary depending on the availability of oxygen and their biological make-up. In many cases the cells are in an oxygen-rich environment. For example, as you sit and read this sentence, you are breathing in oxygen, which is then carried throughout your body by red blood cells. But, some cells grow in envi- ronments without oxygen (yeast in wine-making or the bacteria that cause botulism in canned food), and occasionally animal cells must function without sufficient oxygen (as in running sprints). In this

9.1: Catabolic pathways yield energy by oxidizing organic fuels. Redox reactions: oxidation and reduction. The stages of cellular respiration. In redox reactions the loss of e- from one substance is called oxidation. The gain to the other is known as reduction. The harvesting of energy from glucose by cellular respiration is a cumulative function of three metabolic stages: Catabolic pathways and production of ATP Organic compounds possess potential energy because of the arrangement of electrons in bonds between atoms. Compounds that participate in exergonic reactions can act as fuel. Enzymes help cells degrade complex organic molecules that are rich in potential energy. This breakdown can provide energy to

Types of chemical reactions A chemical reaction is a process that is usually characterized by a chemical change in which the starting materials (reactants) are different from the products. Chemical reactions tend to involve the motion of electrons, leading to the formation and breaking of chemical bonds. There are several different types of chemical reactions and more than one way of classifying them. Here are some common reaction types: Synthesis Reaction (Direct Combination) In a synthesis reaction two or more chemical species combine to form a more complex product. O + H2 ? H2O C + O2 CO2 Chemical Decomposition (Analysis Reaction) In a decomposition reaction a compound is broken into smaller chemical species. H2O ? H2 + O CO2 C + O2
