KEY CONCEPT The process of cellular respiration converts glucose into ATP.

Equation for Cellular Respiration: Respiration is a mirror image of photosynthesis Equation for Cellular Respiration: C6H12O6 + 6O2 6CO2 + 6H2O + _______ NOTE: IT IS IMPORTANT TO KEEP THE PURPOSE OF PHOTOSYNTHESIS AND THE PURPOSE OF CELLULAR RESPIRATION STAIGHT PHOTOSYNTHESIS CREATES GLUCOSE CELLULAR RESPIRATION CREATES ENERGY (ATP)

Overview of Cellular Respiration Glucose Process of Glycolysis If O2 present If no O2 present Aerobic Respiration Anaerobic Respiration

Steps of Aerobic Cellular Respiration (1) Glycolysis * Glucose is broken down * 2 ATP are made (2) Kreb Cycle * 2 ATP are made * CO2 is released Electron Transport Chain * O2 enters, H2O released, 34 ATP made

Step 1: Glycolysis Occurs in the cytoplasm (outside mitochondria) Glucose molecule is broken 2 ATP molecules are produced in the end Glucose

Step 2: Krebs cycle Occurs in the matrix CO2 is released 2 ATP are made H+ released

Step 3: The electron transport chain (ETC) The H+ flow through the inner membrane of the mitochondria, carrying high energy electrons O2 enters from the atmosphere O2 and H+ combine to form H2O 34 ATP are made

ATP Made: Glycolysis makes ______ ATP Kreb Cycle makes ______ ATP ETC makes ______ ATP Total ATP made: ______
