Comparing and Contrasting Photosynthesis and Aerobic Cellular

Comparing and Contrasting Photosynthesis and Aerobic Cellular Respiration

Cellular Respiration and Photosynthesis co-exist as paired metabolic processes.

Photosynthesis uses light energy to convert carbon dioxide into glucose, a simple sugar, in two steps, the light dependent and light independent reactions. Oxygen is produced as a by product during photosynthesis. This reaction stores energy in the chemical bonds of glucose.

Sugar and other carbohydrates are used as fuel sources by cells. During the process of Aerobic Cellular Respiration, glucose is broken down using oxygen. This reaction releases energy which is used to create ATP molecules, the energy carrier molecule of cells. The process also releases Carbon Dioxide as a by product.

Outline a brief summary of the major differences and similarities between these two pathways.
