Textbook Question
Chapter 10, Problem 11PIAT
Can green algae replace “black gold”?
Over the past decade, there has been great interest in developing a sustainable and renewable energy source that would displace our dependence on fossil fuels. Photosynthetic organisms, like the microalgae being cultured in the image above, are currently being used to produce bioethanol, biodiesel, and bio-H2. How are photosynthetic organisms being engineered to promote the production of these biofuels?
Aquatic plants and algae carry out photosynthesis using the same light reactions and Calvin cycle as in land plants. Would you expect any of these organisms to also require the C4 pathway? Describe the problem that is solved by the C4 pathway in land plants and if this could ever be an issue in an aquatic environment.

Climate monitoring demonstrates a continued increase in carbon dioxide concentration in the atmosphere. Most scientists agree that this increased carbon dioxide will also lead to higher temperatures. a) How might future climate change affect metabolic pathways in plant populations? Explain. b) Biotechnologists are currently looking for ways to maintain food sources in climbing heat and carbon dioxide levels, particularly in developing countries. One such endeavor is to convert rice from a C3 to a C4 pathway to increase its photosynthetic efficiency. Will this actually increase its efficiency? Explain.
Atrazine is one of the world’s most used herbicides. It functions by bonding to and disabling a protein in photosystem II. Plants treated with this herbicide die via starvation. Based on this information, what is also true about atrazine-treated plants?
a) Only non-cyclic electron flow is possible.
b) There is not enough ATP created to fuel the Calvin cycle.
c) The plants can switch to C4 pathways.
d) The chloroplast is disabled.
Artificial photosynthesis is being researched to provide:
a)Plastic shrubbery
b)Synthetic fuel
c)Permanent leaves
d)Synthetic proteins

- In addition to the pigments commonly associated with photosynthesis, a certain photosynthetic species contains two additional pigment types. Which of the following best supports the claim that this species is better adapted to environmental changes than other photosynthetic species are? a) The additional pigments allow the species to outcompete other species for the wavelengths of light commonly used in photosynthesis. b) The increased pigment concentration better facilitates energy production within the cells of the species. c) The pigment combination allows the organism to absorb heat as well as light, making better use of available energy. d) The additional pigments allow the species containing them to harvest energy from wavelengths of light that the other photosynthetic species cannot use.arrow_forwardThere is a rare microalga that has a promising future as a producer of a new type of biofuel. After research in the lab, it is found that it is having a difficult time propagating outside of its native environment, and it is identified that this is an issue with its respiration pathway. Overall ATP production is around half of expected,and you find that glycolysis isn’t producing any net ATP molecules and only one molecule of NADH. Question: Assuming that the respiration pathway is similar to other prokaryotes, where would you expect to find a nonfunctional mutation in this pathway? What is the reason for this? What could a growth strategy be that can better support this rare bacterium until you can come up with a long-term solution?arrow_forward34) During photosynthesis, electron transfer follows which sequence?
