Weekly Recap Quiz 8
Please place the following steps of aerobic cellular respiration in order. (Click and drag into the correct position from first (on top) to last (on bottom))
1.:Glucose is present in the cytoplasm 2.Glycolysis 3:Krebs Cycle 4:Electron Transport Cycle
The process by which cells get a small amount of energy without using oxygen is called anaerobic cellular respiration.
True
A cell in the leaf of a green plant performs both photosynthesis and cellular respiration, often at the same time. Which statement best describes how these processes are related to each other?
a. Products of one process are used as some of the reactants for the other process.
Both the wine industry and the bread industry use the process of alcoholic fermentation. In what way does their use of alcoholic fermentation differ?
a. The wine industry uses the alcohol to make the wine; the bread industry uses the carbon dioxide to make the bread dough rise.
A scientist observed that during the course of a chemical reaction in a tissue culture of animal muscle cells, the number of ATP molecules produced was greatly reduced. What did the scientist most likely hypothesize from the observation?
a. oxygen availability became limited
Which are the products of aerobic cellular respiration?
b. water and carbon dioxide and ATP
Cells store short term cell energy when:
c. a third phosphate group is bonded to an ADP molecule
If you run as fast as you can, your muscles may begin to feel weak and have a burning sensation. Explain what is occuring in your muscle cells that accounts for this muscle fatigue.
c. inadequate supply of oxygen to muscle cells leads to lactic acid fermentation
In cellular respiration, the steps following glycolysis depend on whether oxygen is present. Select the BEST explanation:
d. If oxygen is present, production of acetyl-CoA, the citric acid cycle, and electron transport chain follow in order. If no oxygen is present, either lactic acid fermentation or alcoholic fermentation follows.
Aerobic cellular respiration takes place in the ___ of eukaryotic cells.
