SBI3C – Unit 1 Review: Cellular Biology
Cells
1. What are the three statements of the cell theory?
2. Cell diagrams - Know how to identify whether it is a plant cell or an animal cell.
3. Know how to label the organelles (cell parts) of cell diagrams.
4. Be able to match the organelles and their functions. (Eg. Mitochondria produce ATP energy)
5. What organelles are found in plants vs. animals?
6. Explain the role of lysosomes in humans.
Nutrients
1. Why do we need nutrients?
2. What are the functions of carbohydrates?
3. Name the three types of carbohydrates and explain the differences between them.
4. Give an example of a monosaccharide and an example of a disaccharide.
5. Explain why glucose cannot be stored in plant and animal cells. Be specific! What must we
do to fix this?
6. Name five functions of lipids.
7. What is the difference between saturated and unsaturated fats? (The more differences you
give, the better!). Give two examples of each that we see in our daily lives.
8. What are the functions of proteins?
9. How many amino acids are there?
10. What is the difference between essential and non-essential amino acids?
11. Humans make 12 amino acids. The other 8 amino acids… how do we obtain them?
Enzymes (Definition: They are biological molecules that speed up chemical reactions without
being destroyed in a chemical reaction)
1. Review The Lock and key Hypothesis and the diagrams in notes – be able to apply this a to
particular substrate and specific enzyme
 Be able to label a diagram with the key words: Enzyme, substrate, active site,
enzyme-substrate complex, products (understand these words)
2. What is denaturation of proteins? Give real life examples of this and be able to explain it!
3. What environmental factors affect the functionality of proteins/enzymes?
Cell Transport
1. What is the major difference between passive and active transport?
2. What does a “selectively permeable membrane” mean?
3. What are the three types of passive transport?
4. Why can’t all molecules go through a cell membrane? Which types of substances can?
5. Explain the difference between isotonic, hypertonic and hypotonic solutions. Use red blood
cells to explain your answer. (Hint: you can also draw a diagram to help explain your
answer)
6. What does a concentration gradient mean?
7. What is the difference between endocytosis and exocytosis?
8. Endocytosis talks about “cell eating” & “cell drinking”, what are the correct terms for these?
9. Review the processes for the different types of passive and active transport!
Respiration
1. Define autotroph and heterotroph.
2. What is the difference between cellular respiration and photosynthesis?
3. What are the two types of cellular respiration? What is the major difference between these
types?
4. Review lactic acid fermentation.
