Understanding Concepts: 1, 2, 3, 4
What do plants have the unique ability to do?
Read Section 4.5, Cellular Respiration, pages 98 – 101.
Understand the following terms: cellular respiration
the total number of ATPs produced and from what steps
where in the cell this process takes place
glucose – pyruvic acid
aerobic cellular respiration
where the majority of ATP is produced – name it
anaerobic cellular respiration understand why this process occurs (i.e.: in humans)
Label the following Figure:
lactic acid
lactic acid fermentation
alcoholic fermentation
Answer Section 4.5 Review – page 101 and the questions that follow:
Understanding Concepts: 1, 2, 3, 4, 6, 7
Give the full name for ATP. What is ATP used for in the cell? What type of reactions
are these?
When glucose is broken down, what type of reactions are these?
How many ATPs are produced when glucose is converted to pyruvic acid? What is not required
in this step? Where in the cell does this step take place?
Where in the cell does the second step of cellular respiration take place? How many ATPs are
produced in this step?
How come prokaryotic cells do not use aerobic (presence of oxygen) cellular respiration?
Write out the chemical equations for lactic acid fermentation and alcoholic fermentation.
How many ATP are produced using lactic acid fermentation or alcoholic fermentation?
How do these numbers compare to the number of ATPs produced using aerobic
cellular respiration?
