What can be said about the equations for cellular respiration and photosynthesis?

• Products of photosynthesis are the reactants of cellular respiration

• Reactants of photosynthesis are the reactants of cellular respiration

• Products of photosynthesis are not involved in cellular respiration

• Products of photosynthesis are the products of cellular respiration

Which happens during the Calvin cycle?

• release of oxygen

• formation of glucose

• absorption of solar energy

Students planned an investigation using pea plants. They compared the rate of oxygen consumption in pea plants that were watered daily to the rate of oxygen consumption in pea plants that were not watered. Which question were these students most LIKELY investigating?

• Do pea plants carry out photosynthesis?

• Does the amount of water a plant receives affect photosynthesis?

• Is the rate of cellular respiration related to the amount of water a plant receives?

• Do pea plants carry out cellular respiration?

The graph shows data gathered in an investigation of the effect of temperature on the rate of photosynthesis. What explanation is BEST supported by the data in the graph?

• For these plants, the rate of photosynthesis increases as temperature increases from 0 to 20C

• All types of corn plants photosynthesize at the fastest rate of 25 C

• The rate of photosynthesis in these plants will continue to increase as temperatures increase above 25C

• In most types of corn, the rate of photosynthesis is unaffected by temperature.

A student investigated photosynthesis. In her lab report, she wanted to add a diagram summarizing the process. Which flow chart provides the BEST summary of photosynthesis?

• (Inputs) Carbon/Oxygen/Water--(Sunlight)--(Outputs) Carbohydrates

• (Inputs) Carbon/Water--(Sunlight)--(Outputs) Carbohydrates/Oxygen

• (Inputs) Carbon Dioxide/Water--(Sunlight)--(Outputs) Carbohydrates/Oxygen

• (Inputs) Water/Oxygen--(Sunlight)--(Outputs) Carbohydrates/Carbon Dioxide

A large group of human disorders are called mitochondrial diseases. Although there are variations among these diseases, they all involve reduced function of mitochondria. Based on this information, what is the BEST explanation of how these diseases affect the cell's ability to maintain homeostasis?

• Wastes build up in cells

• DNA does not effectively store information

• Not enough energy is produced to power cell functions

• Energy cannot be stored in glucose molecules
