Photosynthesis & Cellular Respiration

Photosynthesis Photosynthesis is the process by which plants store energy from sunlight as glucose Takes place in the chloroplast Chloroplasts contain chlorophyll: a molecule that captures light energy

Carbon dioxide and water are converted to glucose and oxygen Photosynthesis Carbon dioxide and water are converted to glucose and oxygen Energy from sunlight is used to power the reaction Reactants Products

Aerobic Cellular Respiration Cells that have mitochondria (including plants!) can perform aerobic cellular respiration when O2 is present glucose and oxygen are needed to produce a large amount of ATP (between 36 and 38) Carbon dioxide and water are released as waste products Reactants Products

Anaerobic Cellular Respiration Some cells are able to respire without oxygen—this is anaerobic respiration Glucose is broken down to release 2 ATP and various waste products: Lactic acid in muscle cells Alcohol and CO2 in yeast and bacterial cells NO 2 ATP Lactic acid OR Alcohol & CO2 O2 Glucose Reactant Products

Photosynthesis vs. Aerobic Respiration Glucose Occurs in plant cells Occurs in all eukaryotes! H2O 36-38 ATP (cell energy) CO2
