Question

1. Oxygen is a product in:

• aerobic cellular respiration
• fermentation
• photosynthesis

2. Which of the following molecules are classified as air pollutants and as emissions coming out of your car’s tailpipe?

• CO2 and H2O vapor
• NOx and CO2
• NOx and water vapor

3. Perfect gasoline combustion rxns would release:

• HC, O2, N2
• HC, H2O, CO2
• N2, H2O, CO2

4. The DNA parental strand 5’-ACCG-3’ can make a mRNA strand:

• 5’UGGU-3’
• 3’TAAC-5’
• 3’UGGC-5’

5. Cars of the future are being designed using what kind of alternative fuels?

• H2
• O3
• CO

6. The bubbles in bread (and beer!) are formed by:

• CO2
• acetylCoA
• glucose and CO2

7. The function of tRNA includes:

• bringing energy/electrons through the ETC
• releasing energy by breaking chemical bonds
• bringing the amino acid to the mRNA codon
  

8. Polar ice caps melting, more extreme weather, invasive species are consequences of an increase of which molecule?

• CO2
• O3
• NOx

9. Work is:

• converting PE to KE when moving something over a distance
• capturing KE in chemical bonds
• when chemical rxns do not occur

10. Spontaneous chemical reactions are:

• endergonic and release energy
• exergonic and their products contain more energy
• exergonic and release energy

Answer 1

• Oxygen is the product in photosynthesis.
• NOx and CO2 are pollutants from car.
• Perfect gasoline combustion releases CH, H20, CO2.
• Daughter mRNA strand is 3'-UGGC-5'
• Future cars will use H2 as fuel.
• The bubbles in bread are formed by CO2.
• Function of tRNA is to bring the amino acid to mRNA codon.
• CO2 is responsible for polar ice cap melting and other extreme weather conditions.
• Work is conversion of PE to KE when the object moves over a certain distance.
• Spontaneous reactions are exergonic and release of energy.
