Q:
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: Download and fill out this table to compare and contrast Photosynthesis and Aerobic Cellular Respiration. You will submit the completed table for Part 1.

Role of ATP in the reaction
Part 2: After completing the table 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 are the names for the types of organisms that can use Photosynthesis to produce glucose? Provide specific examples.
2. What are the names for the types of organisms can use Aerobic Cellular Respiration to break down glucose to produce ATP? Provide 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 reactions. Briefly, explain the role of enzymes in catalyzing chemical reactions and in metabolic pathways.
Be sure to list and cite in APA, all references used to prepare both parts of this IP assignment.

Preview: ... s within which only a specific substrate can fit to form an enzyme-substrate complex. According to the induced fit hypothesis, “the binding of the substrate to the enzyme at the specific site changes the structure of the enzyme, thus speeds up the chemical reaction.” Cofactors are the nonproteins essential for enzyme activity. For instance, K+. They bind to the enzymes near the active site. For instance, NAD (nicotinamide adenine dinucleotide). Thus, the enzyme-substrate complex and cofactors work together to catalyze the chemical reactions. A metabolic pathway comprises of a series of chemical reactions occurring within a cell. Several enzymes have to work in co-ordination in a specific mode to create metabolic pathways. In case of such pathways, one enzyme considers the product of another enzyme as a substrate. The product is later on passed on to th ...
