Cellular Respiration - Photosynthesis: carbon dioxide + water + solar energy = glucose + oxygen + water ATP - Adenosine triphosphate - Consists of 3 phosphate groups, a ribose sugar and an adenine molecule (nitrogen base – purine) - A form of energy that can be used by all types of cells - created through the process of cellular respiration Aerobic cellular respiration - produces large amounts of ATP (energy) glucose + oxygen carbon dioxide + water + 36 ATP molecules - The process occurs in several stages - The first stage is glycolysis and occurs within the cytosol (cytoplasm) - This process does require oxygen - Glucose splits into two pyruvic acids (pyruvates) glucose 2 pyruvates - The next stage occurs within the mitochondria 2 pyruvates + oxygen carbon dioxide + ATP - lots of folding in inner membrane to increase surface area and space for aerobic cellular respiration - cells that require more energy (ATP) have more mitochondria (example - muscle cells) Anaerobic respiration Ethanol fermentation glucose ethanol + carbon dioxide + 2ATP 🞆 occurs within the cytosol 🞆 occurs in single celled organisms such as yeast and bacteria 🞆 can be used in the production of breads, wine, beer and soy products
