What type of energy does the enzyme Rubisco produce?

Chemical

What is the problem with fossil fuels?

Extraction and use cause environmental damage, and depletion is likely

Generally, energy lost when transferring from one form to another is lost as:

Heat

Which end product is NOT associated with algae farming?

Human Food

Which statement is FALSE regarding Rubisco?

It directly converts ATP and NADPH to glucose

Which of these is a fossil fuel? Biodiesel natural gas algae oil firewood

Natural Gas

What statement represents the correct order of steps in photosynthesis?

1. Sunlight is absorbed 2. An electron is excited 3. ATP is made 4. carbon dioxide is used 5. glucose is made

Which fuel source is the most "green" or most environmentally friendly?

Algae Biofuel

Which fuel source replenishes in the least amount of time? -rapeseed-based biofuel -ethanol-based biofuel -algae biofuel -fossil fuels

Algae biofuel

A company has begun to grow algae, which it intends to use to produce biofuels. What should the company keep in mind as it begins the process of cultivating algae?

Algae require copious amounts of carbon dioxide; the company should be sure its algae are adequately supplied with this gas.

A young husband and wife have decided that they want to grow algae to produce biofuels. They successfully harvest oils, carbohydrates, and proteins from the algae they have grown; however, they are left with hundreds of pounds of algal cell walls. How can they use these cell walls to assure that nothing from their operation is wasted?

Algal cell walls can be burned for electricity and heat or used to organic fertilizer.

What is the difference between biofuels and alternative fuels?

Alternative fuels are any energy source other than petroleum, whereas biofuels come from living organisms.

What is a bioreactor?

An apparatus that contains appropriate nutrients for organism growth

Once extracted, the oil that microalga produce can be processed to make:

Biodiesel fuel, gasoline, & jet fuel

If someone wanted to develop a lighting apparatus (e.g., series of bulbs or tubes) that people in Alaska could use to grow vegetables indoors year-round, which wavelengths should be included in this product?

Blue and Red

What organelle(s) would an algae cell need to be able to carry out photosynthesis?

Chloroplast

What is cyanobacteria?

Photosynthetic Bacteria

Which of these organisms can produce biofuels?

Plants, algae, and microalgae

An egg balanced at the peak of a slanted roof has _____ energy

Potential

Photosynthesis would NOT occur in the absence of:

Sunlight, carbon dioxide, and water

A family has decided that they want to grow algae to produce biofuels. They successfully separate the harvested algae into its primary components so that the processed oil produces the desired biofuel. How can they use the separated carbohydrates to assure that nothing from their operation is wasted?

They can ferment the algal carbohydrates to form additional biofuels

Which statement does NOT explain the importance of photosynthesis organisms to the planet?

They produce petroleum products

Back to Study Plan Which fuel source is INCORRECTLY matched with its associated negative impact? Please choose the correct answer from the following choices, and then select the submit answer button. -fossil fuels: large land use -plant-based biofuel: fertilizer runoff risk -plant-based biofuel: large fresh water requirement -algae biofuel: production cost -fossil fuels: oil or gas environmental contamination risk

fossil fuels: large land use

which combination is not correctly matched?

gasoline; kinetic energy

Chloroplasts are found in the cells of: -all organisms -photosynthetic organisms -organisms capable of converting chemical energy into kinetic energy -heterotrophic organisms

photosynthetic organisms
