Chapter 9.2, Problem 3LO
Summary Introduction
To describe: What happens to an electron in a biological molecule such as chlorophyll when a photon of light energy is absorbed.
Concept introduction: Photosynthesis is a process in which the green plants and algae obtain their nutrients. This process takes place in the chloroplast where chlorophyll molecules are present. The chloroplast contains thylakoid membrane where the light reaction takes place. The end product of the light reaction is the formation of ATP and NADPH, which together helps in driving the Calvin cycle in the stroma of chloroplast.

Describe what happens to an electron in a biological molecule such as chlorophyll when a photon of light energy is absorbed.
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.
In the photosynthesis reaction: 6 CO2 + 6 H2O → C6H12O6 + 6 O2, the substance that serves as the reducing agent is

It is composed of glucose and fructose. Carbohydrates are made by plants which derive their food resources from photosynthesis.

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.arrow_forward
