Q: Which of the following is a mechanisms used to identify an enzyme of interest that will carry out a particular reaction or set of reactions to be used for an industrial process?
- isolate enzymes from an organism which exhibits the desired enzymatic activity
- compare mRNA sequences within a cell in an attempt to identify the presence of a particular enzyme
- create genetically modified organisms by introducing genes selected from an organism which exhibits a particular characteristic into an inactive organisms
- compare isolated enzymes to those in the proteomic database
- all of the above
A: all of the above

Q: Which of the following correctly describes how greenhouse gases impact the Earth’s atmosphere?
- It is a gas which absorbs and traps radiation within the atmosphere
- It is a gas which reduces the oxygen available for living organisms like ourselves to breathe
- It is a gas that reduces the water available for organisms like ourselves to drink
- It is a gas which inhibits the natural flow of materials like nitrogen and phosphorous through the atmosphere
- It is a gas which increases the release of heat into space
A: It is a gas which absorbs and traps radiation within the atmosphere

Q: Which of the following methods are used to convert biomass to biofuel?
- Thermal conversion
- Chemical conversion
- Biochemical conversion
- All of the above
- Thermal and chemical conversion only
A: All of the above

Q: Which of the following correctly describes a biosensor?
- natural or synthetic polymers which are very absorbent and highly biocompatible because they behave similar to biological material
- enzymes that are isolated from living organisms which will be used as chemical agents
- a device that using living organisms or their chemicals to detect a particular material, and a transducer to create a measurable signal of what was detected
- a facility which processes biomass into valuable products such as biofuels and bioreagents
- the modification of industrial processes for the production of goods
A: a device that using living organisms or their chemicals to detect a particular material, and a transducer to create a measurable signal of what was detected

Q: Which of the following is true regarding a biomass supply chains?
- It is a group of organizations, people and practices that link the production, preprocessing, conversion and consumption of products from supplier to consumer
- it is a facility which processes biomass into valuable products such as biofuels and
- it is a group of organizations, people and practices that help to carry out research and development of new products
- it is a series of steps and equipment used for continuous processing
- it is a collection of materials and equipment needed for batch processing
A: It is a group of organizations, people and practices that link the production, preprocessing, conversion and consumption of products from supplier to consumer

Q: What are some potential problems associated with the use of energy crops for the production of biofuel?
- Biofuel is less efficient than fossil fuels for powering vehicles and machinery
- Energy crops are not easily cultivated and require a long time to grow
- nergy crops can only be grown in very specific climates
- The allotment of crops for fuel may reduce the land available for food crops
- All of the above
A: The allotment of crops for fuel may reduce the land available for food crops

Q: Biomass includes materials that are collected from living or recently living things, while fossil fuels represent materials from organisms that have been dead for millions of years.
- True
- False
A: True

Q: Polystyrene is a biopolymer which is considered to be easily biodegradable.
- True
- False
A: False

Q: Batch processing is often preferred to continuous processing as it can generate large amounts of product in the least amount of time.
- True
- False
A: False

Q: Climate change refers to the increasingly hot temperatures present on Earth.
- True
- False
A: False

Q: ___________________________ are substances that are captured from living cells and used as chemical reagents

Q: ___________________________ is used to create genetically modified organisms which possess all of the genes necessary to generate the enzymes needed for a particular process.

Q: Chemical products that are derived from petroleum are known as ___________________________.

Q: ___________________________ is a field which uses biological systems and processes as a template for the design and engineering of new technology.

Q: Explain how the use of biomass in industrial practices can help to reduce greenhouse gas emissions and, thus mitigate climate change.
