Biology Concept Map
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
