Photosynthesis is defined as the chemical process, wherein carbon dioxide in the presence of water and radiant energy gets converted to glucose (chemical energy), giving out oxygen as byproducts. In the equation, the combining reactants and resulting products are expressed along with their respective numbers of molecules. Putting this in a simplified formula, the following equation represents this process. CO2 + H2O + Light energy → C6H12O6 + O2 Considering this equation, how plant lovers (plantitos and plantitas) able to cultivate their plants?
Which of the summary statements below describes the results of the following reaction? C6H1206 + 6 O2 → 6 CO2 + 6 H2O + Energy O C6H1206 is oxidized and O2 is reduced. O 02 is oxidized and H20 is reduced. O CO2 is reduced and 02 is oxidized. O 02 is reduced and CO2 is oxidized.
The law of conservation of matter states that no matter on earth can be created or destroyed. Using the following equation: 6H2O + 6CO2 + Sunlight—> C6H12O6 + 6O2, explain how the process of photosynthesis is an example of this.

Chlorophyll All chemical reactions involve changes in the electrons of atoms. The key to photosynthesis is a special molecule called chlorophyll. This large and complex molecule has electrons that become "activated" when light shines on the molecule. This reaction is unusual because most substances only heat up when exposed to sunlight; that is, their electrons aren't "activated" by light energy. But the electrons in chlorophyll are activated by light, and this electron energy is used to make new plant tissue (C,H12O8). High Energy Electrons www Light Energy Chlorophyll 1. Sunlight contains all of the colors of light in the visible spectrum. Which color do you see reflecting from the surface of plants? 2. Which two primary colors do you not see when looking at the plant leaves? 3. Which colors of sunlight probably activate the electrons in the chlorophyll molecule? Explain.
Which statement describes the results of this reaction: 6 CO2 + 6 H20 + Energy + C6H1206 + 6 O2 ? H2O is reduced and CO2 is oxidized. C6H1206 is reduced and CO2 is oxidized. C6H1206 is oxidized and 02 is reduced. CO2 is reduced and H2O is oxidized.
Photosynthesis is an endothermic reaction because it uses solar energy to build glucose molecules. Rubisco, an enzyme found in plants, is critical to this process. How does the presence of rubisco affect the change in free energy consumed or produced by the reactants and products? The presence of rubisco increases the free energy produced by the reactants, but the free energy consumed by glucose stays constant. The presence of rubisco increases the free energy consumed by glucose, but maintains the free energy produced by the initial reactants. The presence of rubisco decreases the energy required for activation in the transition state and increases the free energy consumed by glucose. The presence of rubisco decreases the energy required for activation in the transition state, but the change in the free energy of the reactants and products remains constant.
Imagine that you are running away from a dinosaur. You are running as fast as you can and breathing hard but you just cannot get enough oxygen to your cells to allow them to keep doing aerobic respiration. Describe how your muscles continue to work and allow you to narrowly escape being eaten. Be sure to include the name and the description of the chemical reaction(s) that save your life. Explain the exact purpose of these reaction(s).
