Quiz Answer Key and Fun Facts

1. The classification of cells as eukaryotic or prokaryotic is based on cell nuclei.

Answer: true

Prokaryotic cells have no nucleus but eukaryotic cells do. Eukaryotic cells have organelles where as prokaryotic cells do not.

2. Which of these is not a phase in the cell cycle?

Answer: Meiosis

The cell cycle is the division of a cell. Children have more cell divisions than adults do.

3. Exocytosis is the process of what?

Answer: Molecules being removed from the cell

Endocytosis is the process of molecules being taken into the cell in intracellular vesicles.

4. What is apoptosis?

Answer: Programmed Cell Death

This is the controlled form of cell death. The uncontrolled form of cell death is called necrosis.

5. What organelle is the site of most of the protein synthesis that occurs in the cell?

Answer: Rough endoplasmic reticulum

The rough endoplasmic reticulum is covered with ribosomes and it is this that synthesizes proteins.

6. How many hydrogen bonds does thymine form in DNA?

Answer: 2

Thymine and adenine two form hydrogen bonds and guanine and cytosine form three hydrogen bonds.

7. The phospholipid bilayer in the membrane is made up of which two molecules?

Answer: Hydrophobic tail and hydrophilic head

Other molecules found in the membrane are cholesterol, proteins and glycolipids.

8. The equation for an enzyme catalysed reaction is E+S-ES-E+P

Answer: True

E stands for enzyme, S stands for substrate and P stands for product. ES stands for enzyme-substrate complex.

9. What is the process that makes the most ATP called?

Answer: Oxidative Phosphorylation

The process of chemiosmosis occurs across the cell membrane.

10. Where does glycolysis occur?

Answer: Cytoplasm

Glycolysis breaks down one molecule of glucose into two molecules of pyruvate.
