A covalent bond between two atoms is formed as a result of the (a) sharing of electrons. (b) transfer of electrons (c) sharing of protons (d) transfer of protons 10. Proteins are polymers made of the following monomer molecules? (a) sugars (b) fatty acids (c) nucleotides (d) amino acids Continued on the reverse side

Explanation / Answer

3. Option D is correct. The nucleus, an organelle found in eukaryotic cells, confines the chromosomes, keeping them separated from the other components of the cell.

4. Option C is correct. Mitochondria has both an outer and an inner membrane.

5. Option D is correct. Mitochondria perform cellular respiration by "burning" sugar and produce ATP.

6.Option C is correct. The scientific name of brewer's yeast, which is an excellent experimental organism used to study eukaryotic cells, is S.cerevisiae.
