Chapter 8 Study Guide

What atoms make up glucose?

• Carbon, Hydrogen, and Oxygen

• Carbon, Nitrogen, and Oxygen

• Hydrogen, Nitrogen, and Sulfur

• Oxygen, Phosphorus, and Sulfur

Plants get carbon atoms from the source and the name of the molecule is:

• Water and Glucose

• Soil and Nitrogen

• Air and Carbon Dioxide

• Sunlight and Oxygen

How do carbon atoms get rearranged during photosynthesis?

• Carbon atoms are rearranged into glucose molecules.

• Carbon atoms are released as carbon dioxide.

• Carbon atoms are converted into oxygen.

• Carbon atoms remain unchanged.

Carbon moves from plants to animals through the process of:

• photosynthesis

• respiration

• consumption

• decomposition

What is the chemical equation for cellular respiration? Label the INPUTS and OUTPUTS in the equation.

• C6H12O6 + 6O2 -> 6CO2 + 6H2O

• C6H12O6 + 6CO2 -> 6O2 + 6H2O

• 6CO2 + 6H2O -> C6H12O6 + 6O2

• C6H12O6 + 6H2O -> 6CO2 + 6O2

Which model shows the INPUTS and OUTPUTS of a person performing cellular respiration, with the movement of carbon atoms highlighted throughout?

• Model A

• Model B

• Model C

• Model D

What is the chemical equation for cellular respiration?

• C6H12O6 + 6O2 -> 6CO2 + 6H2O + energy

• C6H12O6 + 6O2 -> 6CO2 + 6H2O

• C6H12O6 + 6O2 -> 6CO2 + 6H2O + ATP

• C6H12O6 + 6O2 -> 6CO2 + 6H2O + heat

In the process of photosynthesis, which substances are used by plants to produce glucose and oxygen?

True or False: The same atoms we started with during cellular respiration are the same atoms we ended with, they are just moving around.

• True

• False

What is required for photosynthesis to occur?

• Water and sunlight

• Oxygen and nitrogen

• Carbon dioxide and oxygen

• Glucose and nitrogen
