Question: Answer the following question given this paragraph: Biomass is another renewable source of energy. Biomass includes wood, grains, and other plant materials or waste materials. People can burn wood directly for energy in the form of heat. Biomass can also be processed to make biofuel. Biofuel is a fairly new type of energy that is becoming more popular. Biomass is useful because it can be made liquid. This means that they can be used in cars and trucks. Some car engines can be powered by pure vegetable oil or even recycled vegetable oil. Sometimes the exhaust from these cars smells like French fries!. Q: Biomass can also be processed to make what kind of fuel? A:
OPTIONS:
- hydrogen fuel
- gasoline
- fossil
- biofuel
Answer: biofuel

input with options: Answer the following question given this paragraph: Roundworms make up the phylum Nematoda. They have a pseudocoelom and hydrostatic skeleton. Their body is covered with tough cuticle. Free-living roundworms are found mainly in freshwater habitats. Parasitic roundworms have a variety of hosts, including humans. Q: What has a pseudocoelom and hydrostatic skeleton? A:
OPTIONS:
- vertebrates
- omnivores
- gymnosperms
- roundworms
output: roundworms

Q: Answer the following question given this paragraph: The epidermis also contains melanocytes , which are cells that produce melanin. Melanin is the brownish pigment that gives skin much of its color. Everyone has about the same number of melanocytes, but the melanocytes of people with darker skin produce more melanin. The amount of melanin produced is determined by heredity and exposure to UV light, which increases melanin output. Exposure to UV light also stimulates the skin to produce vitamin D . Because melanin blocks UV light from penetrating the skin, people with darker skin may be at greater risk of vitamin D deficiency. Q: People with which skin type run a greater risk of vitamin d deficiency? A:

OPTIONS:
- lighter skin
- brighter skin
- weaker skin
- darker skin

A: darker skin

input: OPTIONS:
- vessel - substrate complex
- nucleus - substrate complex
- lock and key model
- enzyme - substrate complex Now, answer this question: Answer the following question given this paragraph: View an animation (http://openstaxcollege. org/l/hexokinase2) of induced fit. When an enzyme binds its substrate, an enzyme-substrate complex is formed. This complex lowers the activation energy of the reaction and promotes its rapid progression in one of multiple possible ways. On a basic level, enzymes promote chemical reactions that involve more than one substrate by bringing the substrates together in an optimal orientation for reaction. Another way in which enzymes promote the reaction of their substrates is by creating an optimal environment within the active site for the reaction to occur. The chemical properties that emerge from the particular arrangement of amino acid R groups within an active site create the perfect environment for an enzyme's specific substrates to react. The enzyme-substrate complex can also lower activation energy by compromising the bond structure so that it is easier to break. Finally, enzymes can also lower activation energies by taking part in the chemical reaction itself. In these cases, it is important to remember that the enzyme will always return to its original state by the completion of the reaction. One of the hallmark properties of enzymes is that they remain ultimately unchanged by the reactions they catalyze. After an enzyme has catalyzed a reaction, it releases its product(s) and can catalyze a new reaction. Q: What is formed when an enzyme binds its substrate? A:
A:
output: enzyme - substrate complex
