Name: _____________________
Per: ____
1. What is Cell Respiration?
a. The breakdown of _______________ to form ________ energy use in cells.
b. ________________ is the type of energy used by cells to drive reactions in the body.
c. The equation: **MEMORIZE THIS! 6O2 + C6H12O6 -------------------------6H2O + 6CO2 + 36 ATP
d. Write the equation in word version:
e. Describe how the cells get oxygen to each cell. Must use the terms passive diffusion, lungs, breathing, oxygen,
blood, heart, carbon dioxide (waste product), cells, and cellular respiration, ATP. 5 to 6 sentences. RSQ
f.
Describe how the cells get the necessary glucose to each cell. Must use the term digestion, polymers,
monomers, absorption, small intestines, active transport, capillaries, blood transport, delivery, cells, cellular
respiration, ATP. 5 to 6 sentences
2. Glycolysis: The first reactions is called glycolysis, which means
. The process occurs in
the _____________________of the cell. _____________________ is broken down in to 2 molecules of pyruvate.
The process uses ________ ATP molecules to start, then makes ______ ATP, so net gain= ___________
a. Many vitamins and minerals are necessary components of cellular respiration, such as vitamin C, thiamin (B1),
riboflavin (B2), Niacin (B3), cobalamin (B12), etc. What would happen to energy levels with a deficiency of B
vitamins? RSQ
b. Which phase of cellular respiration do NADH and FADH2 move to after gaining electrons and hydrogen?
3. Aerobic Respiration: Occurs when
is available. The process occurs in the organelle known as the
__________________________,which is also called the powerhouse of the cell. The two parts of aerobic
respiration include the Krebs cycle and Electron Transport chain.
Krebs Cycle or Citric Acid Cycle
Forms __________ ATP and CO2, which is a waste product.
List three types of organisms that use cellular respiration
NADH and FADH travel to
Electron Transport Chain (ETC)
Forms _________ ATP
Oxygen forms bonds with H+ ions which makes _______________.
Describe the importance of NADH and FADH2 in making ATP? (minimum of 4 to 5 sentences) RSQ and use the
terms, hydrogen, electrons, concentration gradient, mitochondria, ATP synthase, ADP, ATP
4. Name the three processes of aerobic cellular respiration. How many ATP’s does each process produce, and what
is the total ATP produced from one glucose molecule?
3 Processes of Cellular Respiration:
# ATP produced:
Total ATP =___
5. Describe ways ATP is used in the body. RSQ – list at least 3.
6. Anaerobic Respiration: Occurs when _______________ is available.
a. Equation for lactic acid fermentation-b. Equation for alcoholic fermentation-Compare lactic acid fermentation and alcoholic fermentation by describing what pyruvic acid is changed in to. Be sure to
include what type of organism each one takes place in. In the absence of oxygen pyruvate (3
sugars)
made in
move to
(anaerobic or aerobic ATP production)
What is pyruvic acid changed into?
Organism:
Alcoholic Fermentation
Lactic Acid Fermentation
7. Approximately, how many seconds worth of ATP is available for excess activity?
8. When and why does our body use lactic acid fermentation? How many seconds worth of lactic acid fermentation can
occur in our body? What type of energy production happens after excess lactic acid is built up in our bodies.
9. Why is it necessary to pace yourself during cellular respiration of glucose stores (glycogen)? RSQ
10. After glycogen is used up, what macromolecule is burned for energy?
