  1. 1What are the correct base pairings in DNA?
    1. AA - C, G - T
    2. BC - G, A - T
    3. CT - C, G - A
  2. 2Tick all that apply about DNA.
    1. AIt is a polymer.
    2. BIt has 6 different possible base pairing combinations.
    3. CIt is made of nucleotides.
    4. DIt has a triple helix structure.
    5. EDNA is inside the chromsomes which are in the gene.
    6. FDNA is inside the genes which are in the chromosomes.
  3. 3Each base in [blank_start]DNA[blank_end] forms [blank_start]cross[blank_end] links with their [blank_start]complementary[blank_end] pairs on the other strand, keeping the strands [blank_start]tightly[blank_end] wound together.

    Complementary pairing also allows and helps [blank_start]protein[blank_end] synthesis.
    1. ADNA
    2. Bcross
    3. Ccomplementary
    4. Dtightly
    5. Eprotein
  4. 4Protein synthesis takes place in the [blank_start]cytoplasm[blank_end] and is aided by the [blank_start]ribosomes[blank_end].

    The order of bases in a gene code for a different order of amino acids in a protein. Each amino acid is coded for by a sequence of [blank_start]three[blank_end] bases called a [blank_start]triplet[blank_end] code.

    A [blank_start]shorter[blank_end], single strand of DNA (called mRNA) goes through the unzipped DNA and matches each base with their [blank_start]complementary[blank_end] pair. This is called [blank_start]transcription[blank_end].

    The mRNA leaves the nucleus and enters the cytoplasm, where the [blank_start]ribosomes[blank_end] read the [blank_start]triplet[blank_end] codes and form the correct sequence of amino acids, joining them together to make a [blank_start]protein[blank_end].
    1. Acytoplasm
    2. Bnucleus
    3. Cmitochondria

    17. Qtranslation
    18. Rtranscription
    19. Sribosomes
    20. Tmitochondra

    23. Wquadruplet
    24. Xprotein
    25. Yring
  5. 5Enzymes are [blank_start]biological[blank_end] catalysts. They help to speed up reactions without [blank_start]damaging[blank_end] themselves or getting 'used up'.

    Enzymes are [blank_start]proteins[blank_end] and are [blank_start]very[blank_end] specific.

    The [blank_start]lock[blank_end] and key method means the substrate can only enter the active site of the enzyme that has been built to break down that substrate.

    Carbohydrase (example: [blank_start]amylase[blank_end]) break down carbohydrates into [blank_start]starch[blank_end] and simple sugars.
    Protease (example: [blank_start]pepsin[blank_end]) break down proteins into amino acids.
    Lipase (example: [blank_start]lipids[blank_end]) break down [blank_start]fats[blank_end] and oils into fatty acids and [blank_start]glycerol[blank_end].
    1. Abiological
    2. Benvironmental
    3. Cpretty cool
    4. Ddamaging
    5. Eexploding
    6. Fproteins
    7. Gsingle amino acids
    8. Hvery
    9. Inot very
    10. Jlock
    11. Kdoor
    12. Lamylase
    13. Mstarch
    14. Npepsin
    15. Olipids
    16. Pfats
    17. Qglycerol
    18. Rsugar
  6. 6Enzymes all have optimum pHs, temperatures and [blank_start]concentrations[blank_end].

    The optimum means the enzyme is working at its [blank_start]highest[blank_end] possible efficiency.
    Too high or too low of a pH effects the [blank_start]bonds[blank_end] between enzymes and substrates, slowing the rate of reaction.

    If an enzyme concentration is increased, eventually the rate of reaction will remain the [blank_start]same[blank_end] as all the [blank_start]substrates[blank_end] have been broken down.

    If the substrate concentration is increased, eventually the rate of reaction will remain the [blank_start]same[blank_end] as all the active sites are [blank_start]full[blank_end].

    1. Aconcentrations
    2. Bhighest
    3. Cbonds
    4. Dsame
    5. Esubstrates
    6. Fsame
    7. Gfull
  7. 7Match the chemical with what they test for and how it is shown.

    Ethanol tests for [blank_start]fats[blank_end]. It has a [blank_start]creamy precipitate[blank_end] if it is present and clear if it is not.
    Iodine tests for [blank_start]starch[blank_end]. It is [blank_start]black / purple[blank_end] when it is present and [blank_start]yellow[blank_end] if it is not.
    Benedict's solution tests for [blank_start]reducing sugars[blank_end]. It is [blank_start]red[blank_end] if it is present and [blank_start]blue[blank_end] if it is not.
    Buiret solution tests for [blank_start]protein[blank_end]. It is [blank_start]pink[blank_end] if it is present and blue if it is not.
    1. Afats
    2. Bstarch
    3. Ccreamy precipitate
    4. Dblack / purple
    5. Eyellow
    6. Freducing sugars
    7. Gred
    8. Hblue
    9. Iprotein
    10. Jpink
  8. 8Respiration is the process of [blank_start]transferring[blank_end] energy from the break down of sugar.
    The energy transferred [blank_start]can't[blank_end] be used directly by the cells, so it is used to make [blank_start]ATP[blank_end].

    [blank_start]Aerobic[blank_end] respiration happens when there is plenty of oxygen available.

    Glucose + oxygen -----> carbon dioxide + [blank_start]water[blank_end] + energy

    [blank_start]Anaerobic[blank_end] respiration produces less [blank_start]energy[blank_end]. Glucose is broken down to make [blank_start]lactic[blank_end] acid (in animals) or [blank_start]ethanol[blank_end], carbon dioxide and energy (in [blank_start]yeast[blank_end] and fungi).
