Quiz Answer Key and Fun Facts
1. How do enzymes catalyse reactions?

Answer: They change the activation energy.

Enzymes decrease the activation energy (the energy which is needed to start off the reaction), and also increase the speed of the reaction.
2. Why does water provide a relatively stable external environment for aquatic organisms?

Answer: Its temperature varies much less than air temperature

The other three points are true of water but they do not take a part in providing a stable environment for aquatic animals.
3. CH3CH2COOH is an example of which of these molecules?

Answer: An alkanoic (fatty) acid

Tricarboxylic acids and amino acids share the same carboxyl group but have different functional groups joined to them. An example of a monosaccharide is glucose (C6H12O6).
4. The DNA of a particular cell is damaged so that the cell continues to divide uncontrollably. What is the possible result?

Answer: Tumour Formation

5. Which of these structures is the smallest?

Answer: A virus

6. What are enzymes in plant cells made from?

Answer: Protein

Enzymes in plant and animal cells are made from proteins.
7. Compared to a diploid cell, how much genetic material would the nucleus of a haploid cell of the same organism contain?

Answer: Half

An example of a haploid cell is an egg cell (gamete) which only contains half the genetic material of the mother's cells. A diploid cell is just a regular cell.
8. Which of these characteristics are shown by the gene controlling ABO blood groups?

Answer: Codominance

If a person has an Ai gene and a Bi gene, their blood type will be AB. This shows codominance. Codominance is where two differeent alleles both show themselves in the phenotype of a person. Another example would be in the gene for type of hair. There are two alleles: one for curly hair, and one for straight hair. Someone who is heterozygous for these alleles would have wavy hair.
9. Which function is carried out by the Golgi apparatus?

Answer: Modification of proteins for secretion

10. A woman is heterozygous for a recessive X-linked allele that causes haemophilia. Which statement is correct?

Answer: She is a carrier of Haemophilia

She is a carrier because haemophilia is a recessive trait and she only has one of the recessive alleles. However, in the case of males, one of the recessive alleles would make them a sufferer because it is carried on the X chromosome and males only have one X chromosome.
Did you know that there is a line of Haemophilia in the British Royal family?
