PAP Practice Test - Cell Transport and Energy Conversions

The diagram illustrates the activity of vesicles during a cellular process.

Which statement best explains the function of the vesicles?

• Delivering packaged materials to the Golgi apparatus for protein synthesis

• Exchanging genetic information between the Golgi apparatuses of separate cells

• Extracting portions of the Golgi apparatus to be regenerated for growth within the cell

• Transporting packaged molecules from the Golgi apparatus to be released out of the cell

When mammals get an infection, their internal body temperature often rises 2 to 3 degrees Celsius. The body gets the energy it needs to react to an infection by —

• increasing the rate of cellular division

• decreasing the rate of glucose movement into the cell

• increasing the rate of cellular respiration in mitochondria

• decreasing the rate at which carbon dioxide is removed from the cell

When a sea urchin egg is removed from the ocean and placed in freshwater, the egg swells and bursts. Which of these causes water to enter the egg?

• Coagulation

• Sodium pump

• Active transport

• Osmosis

The illustration above shows a cell model with starch solutions both inside and outside the cell. In which of the following situations will the solution rise highest in the tube?

• 
• 
• 
• 

Which statement is supported by the diagram?

• The mitochondrion uses the sun’s energy directly.

• The end products of photosynthesis do not provide energy for cellular respiration.

• The main source of energy for photosynthesis is carbohydrates.

• Carbohydrates are converted into ATP by the mitochondrion.

Which statement explains how producers are dependent upon consumers for their survival?

• Consumers supply oxygen for producers to undergo aerobic respiration.

• Consumers produce carbon dioxide for producers to use during photosynthesis.

• Consumers provide chemical energy needed by producers for cellular respiration.

• Consumers make lactic acid that producers use in photosynthesis.

Photosynthesis and cellular respiration both involve the use and release of gases. Which statement correctly identifies the role of gases in the two processes?

• Photosynthesis and cellular respiration both use carbon dioxide and release oxygen.

• Photosynthesis and cellular respiration both use oxygen and release carbon dioxide.

• Cellular respiration uses oxygen and releases carbon dioxide, while photosynthesis uses carbon dioxide and releases oxygen.

• Cellular respiration uses carbon dioxide and releases oxygen, while photosynthesis uses oxygen and releases carbon dioxide.

Diatoms are one of the most common types of phytoplankton in marine habitats. Like plants, diatoms contain chlorophyll and produce glucose from which of the following?

• O2 and ATP

• CO2 and O2

• ATP and H2O

• CO2 and H2O

Why are photosynthesis and cellular respiration often considered opposites?

• Photosynthesis produces twice as many ATP molecules as cellular respiration does.

• Water is released during photosynthesis and consumed during cellular respiration.

• Photosynthesis occurs during the day, and cellular respiration occurs at night.

• Oxygen is produced during photosynthesis and used during cellular respiration.

The diagram below illustrates how plant root cells take in mineral ions from the surround soil.

Which of the following processes is illustrated?

• active transport

• osmosis

• diffusion

• passive filtration
