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 byproduct.

Part 1: Fill out a table to compare and contrast Photosynthesis and Aerobic Cellular Respiration. You will submit the completed table for Part 1.

Part 2: After completing the table above you will have a basic understanding of these two complementary metabolic processes. Using what you have learned, and additional reference information, answer the following questions.

1. What is the name given to the types of organisms that can use photosynthesis to produce glucose? In addition, provide THREE specific examples..
2. What is the name given to the types of organisms that exclusively use aerobic cellular respiration to break down glucose to produce ATP for energy? In addition, provide THREE specific examples.
3. If oxygen is lacking, how might cells meet their energy needs through fermentation? Explain and give some examples of cells that can do this.
4. Both photosynthesis and aerobic cellular respiration are examples of complex metabolic pathways, consisting of many linked chemical reactions that require enzymes to function. Briefly, explain two (ONLY TWO) attributes of enzymes in catalyzing chemical reactions and in metabolic pathways.
