2.3 QUIZ on Cellular Respiration

Which statement best compares aerobic and anaerobic respiration?

• Less ATP is generated during anaerobic respiration than during aerobic respiration.
• More water is generated during anaerobic respiration than during aerobic respiration.
• More oxygen is generated during anaerobic respiration than during aerobic respiration.
• Less lactic acid is generated during anaerobic respiration than during aerobic respiration.

A student prepared a test tube containing yeast, glucose, and water. After 24 hours, the test tube was analyzed for the presence of several substances. What substance would the student expect to find if respiration occurred in the test tube?

• starch
• lipids
• nitrogen
• carbon dioxide

The arrow below each lettered process indicates where the process takes place. Glucose is a PRODUCT of which process shown?

• Process A, only
• Process B, only
• Processes A and C
• Processes B and C

Two test tubes were filled with a solution of bromothymol blue. A student exhaled through a straw into each tube, and the bromothymol blue turned green. Two aquatic green plants were placed into each tube, and the tubes were corked. One tube was placed in the dark, and one was placed in direct light. The green solution in the tube in dark turned yellow, while the one in the light turned blue. Why did the solution in the tube placed in the dark turn from green to yellow?

• Oxygen was produced by photosynthesis.
• Oxygen was removed by respiration.
• Carbon dioxide was removed by photosynthesis.
• Carbon dioxide was produced by respiration.

In the diagram of a cell shown below, which number indicates the structure in which most of the enzymes involved in aerobic cellular respiration function?

• 1
• 2
• 3
• 4

Which is true regarding photosynthesis and cellular respiration?

• The reactants in photosynthesis match the products in cellular respiration.
• The useful products of both photosynthesis and cellular respiration are the same.
• Both photosynthesis and cellular respiration turn light energy into chemical energy.
• The process of photosynthesis happens in plants only, while the process of cellular respiration happens in animals and fungi only.

Which statement best distinguishes aerobic from anaerobic respiration?

• Only aerobic respiration requires oxygen.
• Only aerobic respiration involves fermentation
• Only anaerobic respiration occurs in the mitochondria.
• Only anaerobic respiration produces carbon dioxide.

The diagram below represents part of cellular respiration. Energy is released and made available for metabolic activities at

• Step 1, only
• Step 2, only
• Both Step 1 and Step 2
• Neither Step 1 nor Step 2

Which substances are produced as a result of the process of aerobic respiration?
