Textbook Question
Chapter 10, Problem 13PIAT
One of the contributing factors to environmental pollution and climate change is the production of CO2 via the combustion of fossil fuels. What is a benefit of using biofuels, produced by living organisms, if they will release similar amounts of CO2 when used to meet our energy demand?

As the sun shines on Earth, plants use its energy to complete the process of photosynthesis. Energy is transformed during the process into chemical energy in the form of sugars, such as carbohydrates. However, the energy available at top consumers is much less than that produced by autotrophs. Why is this so?

One group of such microorganisms are lithotrophs. These are found deep beneath the Earth's surface, living on rocks under anaerobic conditions and surviving on CO2 as their sole source of carbon. Imagine that you are studying a newly discovered lithotroph and are trying to determine what it uses as a source of electrons for reducing CO2 and for producing energy. Which one of the following conditions must be met for a molecule to serve as a useful electron donor? Oxidation of the molecule occurs with a decrease in free energy. Oxidation of the molecule occurs with an increase in free energy. Reduction of the molecule occurs with a decrease in free energy. O Reduction of the molecule occurs with an increase in free energy.arrow_forward
