Unit 1 Study Guide worksheets:
Be sure to review the unit test study guide and highlight any concepts you are
having difficulty with.
The following sheets are intended to help you test your knowledge, they are a
supplement to the study guide already provided. Be sure you know all the main
points from the main study guide sheet!!
1. List the four parts of cell theory.

You have already completed a sheet like this, but it is a good review of cell membrane and
transport. Review your in-class activity as well. The pictures will be a great help for
understanding the different transport mechanism.
Cell Membrane and Cell Transport Review
Cell Membrane:
1. Sketch the cell membrane.
2. Describe the structure of phospholipids using the terms hydrophilic and hydrophobic.
3. What are the two important jobs of the membrane?
4. Why is it important for the cell membrane to be selectively permeable?
5. Describe the function of four proteins found in the cell membrane.
6. Why is turgor pressure not used in reference to animal cells?
Cell Transport:
1. Fill in the following chart:
Passive Transport
Diffusion
Osmosis
Facilitated Diffusion
Active
Transport
Requires energy
Requires special proteins in
membrane
Moves from _____ to _____
concentration
Moves water, solute or both
2. Identify each of the following as passive transport (P) or active transport (A).
a) _____ diffusion
b) _____ endocytosis
c) _____ exocytosis
d) _____ facilitated diffusion
e) _____ osmosis
f) _____ phagocytosis
g) _____ pinocytosis
3. Discuss three factors that affect diffusion rates
4. What factor determines the direction in which molecules will move during osmosis?
5. How does water move when a cell is placed in a hypotonic solution? A hypertonic solution? What happens
to the size of a cell placed in a hypotonic solution? A hypertonic solution?
6. When cells are placed in isotonic solutions, which direction does water move and what happens to the
cells?
Cellular Respiration and Photosynthesis
1. List three activities that take place in the cell that rely on ATP molecules.
2. Make a diagram of ATP and show how energy is released from this molecule.
3. What is glycolysis? Where does it occur?
4. Identify the main phases of cellular respiration. Which of these produces the most ATP?
5. How is oxygen important for the release of energy in aerobic cellular respiration?
6. Write the simple equation for cellular respiration.
7. Which molecule in question 1 has the greatest potential energy?
8. Cellular respiration transforms the chemical energy in glucose. Where does the energy go?
9. These organisms serve as ultimate sources of food for most life on earth.
10. Most food webs start with this.
11. These are discrete packets of solar radiation that travel in waves.
12. This process involves a series of chemical reactions by which light energy from the sun is
used to transform carbon dioxide and water into energy rich food molecules.
13. This is chemical formula for photosynthesis.
14. Name the first and second stages of photosynthesis and briefly describe what happens in
each stage (be sure to use the terms light dependent/ independent, talk about reactants and
products, where does each stage take place?)
15. Ultimately, all energy can be traced back to this.
16. The name for organisms who gain their energy in the form of chemical energy from the
consumption of plants or animals.
17. This high energy molecule is composed of a ribose sugar, adenine and three phosphate
groups.
18. The name for special molecules that are able to absorb specific colours of light.
19. The name for specialized cell membranes found in the chloroplasts.
20. When struck by light, chlorophyll pigments transmit or reflect this colour light.
21. The name for a protein molecule that increases the rate at which biochemical reactions
proceed.
22. The thick fluid found in between the grana.
23. The metabolic pathway found in the choloroplast where carbon enters in the form of CO2
and leaves in the form of sugar with the help from ATP.
24. Write out the balanced summary equation for photosynthesis
25. The chemical process by where carbohydrates are broken down to be a quick source of ATP.
26. Write the balanced chemical formula for cellular respiration.
27. List the three phases of cellular respiration.
28. In which phase is glucose separated into two smaller parts?
29. In this phase, additional hydrogen and carbon dioxide molecules are extracted.
30. What is the net gain of ATP from the Krebs cycle?
31. This is a series of steps where electrons move along allowing for a slow release of energy.
32. How many ATP are produced from the ETC?
33. This process occurs in the cytoplasm of the cell and doesn’t require oxygen.
34. These two processes occur in the mitochondria and require oxygen to be present.
35. How many carbon dioxide molecules are produced from the Krebs cycle?
