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 byproduct.

Please compare and contrast photosynthesis and aerobic cellular respiration.

What types of organisms can use Photosynthesis to produce glucose? Provide exs.

What types of organisms can use Aerobic Cellular Respiration to breakdown glucose to produce ATP? Provide exs.

If oxygen is lacking, how might cells meet their energy needs through fermentation? describe and give some exs of cells that can do this.

Both reactions are exs of complex metabolic pathways, consisting of many linked reactions. Briefly, describe the role of enzymes in chemical reactions and metabolic pathways.
