This document provides an overview of bioenergy and biofuels. It discusses key topics like photosynthesis, biomass sources for biofuels, and the conversion processes to produce ethanol, biodiesel, and other drop-in fuels. The summary concludes that biofuels can help reduce greenhouse gas emissions and reliance on petroleum for transportation fuel while supporting more sustainable energy sources.

9. This is a complex sugar compound
that is used to store future energy
needs or to build new tissues, and is
created from excess glucose from
photosynthesis. It is also the most
common carbohydrate in the human
diet.

25. Biodiesel is a renewable fuel that
can be manufactured from plant
or animal-based fats and oils. Oils
and fats are considered this class
of macromolecules.

29. Cellulase, which breaks down
cellulose molecules into simple
sugars, is an example of this class
of protein that accelerates
chemical reactions.

31. Renewable gasoline, jet fuels, and
diesel fuels are composed
primarily of molecules containing
atoms of hydrogen and carbon,
which are classified as this type of
compound.

35. Ethanol is typically mixed with
this type of transportation fuel in
blends of E10, E15, or E85
(depending on the percentage of
ethanol).
AnswerReturn to Main Board
39. E85 is an ethanol blend that can
only be used in this type of
vehicle, which is designed to
tolerate the fuel's high ethanol
content and standard gasoline,
interchangeably.
