A. Row 1
B. Row 2
C. Row 3
D. Row 4
Base your answers to questions 2 & 3 on the diagrams below and your knowledge of
biology. The arrow below each lettered process indicates where the process takes
place.
2. Process A is known as

B. fermentation
C. dehydration synthesis
D. aerobic respiration
3. Glucose is a product of
A. process A, only
B. process B, only
C. process B and process C
D. process A and process C
4. Which statement best compares the energy transformations of photosynthesis and
cellular respiration?
A. Only photosynthesis uses oxygen to create energy.
B. Only photosynthesis causes an increase in kinetic energy.
C. Photosynthesis and cellular respiration both store energy in chemical bonds.
D. Photosynthesis and cellular respiration both require chemical energy to make food.
5. A student prepared a test tube containing yeast, glucose, and water. After 24 hours, the
test tube was analyzed for the presence of several substances.
What substance would the student expect to find if respiration occurred in the test
tube?
A. a hormone
C. nitrogen
B. starch
D. carbon dioxide
6. One type of anaerobic respiration results in the production of
A. water and oxygen
C. nitrogen gas and ammonia
B. pyruvic acid and glycerol
D. alcohol and carbon dioxide
7. Which of the following diagrams accurately represents the use of gases in both cellular
respiration and photosynthesis A
8. Photosynthesis and cellular respiration are two major processes of carbon cycling in
living organisms. Which statement correctly describes one similarity between
photosynthesis and cellular respiration?
A. Both occur in animal and plant cells.
B. Both include reactions that transform energy.
C. Both convert light energy into chemical energy.
D. Both synthesize organic molecules as end products.
9. The diagram below represents a cell found in some complex organisms. The enlarged
section represents an organelle, labeled X, found in this cell.
Describe the function of organelle X and explain how it is important to the survival of
the cell. In your answer, be sure to:
 Identify organelle X
 State the process that this organelle performs
 Identify the two raw materials that are needed for this process to occur
 Identify one molecule produced by this organelle and explain why it is
important to the organism
