Cellular Respiration Exam Questions with Correct Answers 100% Verified|
Guaranteed Success
What process occurs after glycolysis if oxygen is available for cellular respiration? Krebs
Cycle
Describe what occurs during the Krebs Cycle. The products of pyruvic acid and NADH of
glycolysis are converted to carbon dioxide, 2 molecules of ATP, and electron carriers.
What is the purpose of the electron transport chain? The electron transport chain transports
high-energy electrons supplied by the Krebs Cycle to carrier molecules to convert ADP to ATP
molecules.
If 10 glucose molecules enter the Krebs Cycle, how many possible molecules of ATP can be
produced? Show your work. 10 x 36 = 360 molecules of ATP
What is the difference between aerobic respiration and anaerobic respiration? Which process
creates the most ATP? Aerobic respiration takes place in the presence of oxygen, while
anaerobic respiration takes place without oxygen present. Aerobic respiration produces the
most ATP.
Summarize the process of lactic acid fermentation. The pyruvic acid produced during
glycolysis is converted to alcohol, carbon dioxide, and NAD+. No carbon dioxide is produced.
What foods are made with lactic acid produced by prokaryotic bacteria? Yogurt, cheeses,
buttermilk, sour cream, and pickles.
Why do you feel a sore burning sensation in your muscles when you exercise strenuously?
The lactic acid byproduct of lactic acid fermentation builds up in muscle cells and causes this
sensation.
