Biology-Cellular Respiration
Consider the stage of cellular respiration that is shown in the diagram. What is the net ATP gain at this stage of cellular respiration?
2.
How many ATP are generated in the electron transport chain?
32.
What is the main difference between aerobic respiration and anaerobic respiration?
Aerobic respiration requires oxygen to proceed, but anaerobic respiration does not.
What do alcohol fermentation, acetyl CoA formation, and the Krebs cycle have in common?
All produce carbon dioxide.
Which statement about anaerobic respiration is true?
Anaerobic respiration is used commercially in the production of beer, wine, bread, yogurt, and cheese.
What do aerobic respiration and anaerobic respiration have in common?
Both start with glycolysis.
Which is required for both anaerobic respiration and aerobic respiration?
Glucose.
During glycolysis, glucose is broken down into two molecules of pyruvate. What is the main transformation that occurs during glycolysis?
Glycolysis produces pyruvate, ATP, and NADH by oxidizing glucose.
The graphic shows the citric acid cycle. During the citric acid cycle, what happens to acetyl-CoA?
It enters the citric acid cycle and associates with a 4-carbon molecule, forming citric acid, and then through redox reactions regenerates the 4-carbon molecule.
Which statement about cellular respiration is true?
It is used by every living cell.
What role does cellular respiration play in the water cycle?
It releases H20 to the atmosphere during electron transport.
Which is a commercial use for lactic acid fermentation?
Making cheese.
The venn diagram compares aerobic respiration and anaerobic respiration. Which statement should be categorized only in the aerobic section of the venn diagram?
Produces water.
The equation shows cellular respiration. During cellular respiration, glucose combines with oxygen to form carbon dioxide, water, and ATP.
The energy is transferred to ATP.
Which statement describes the reaction for cellular respiration?
The equation is glucose+oxygen > carbon dioxide+water and energy is produced in the form of ATP.
