C6H12O6+6O2→6CO2+6H2O+energy is the balanced chemical equation for which process?

• Photosynthesis

• Glycolysis

• Cellular respiration

• Krebs cycle

In the process of photosynthesis, plants take in carbon dioxide (CO2) from the atmosphere and water (H2O) from the soil. Using the energy of sunlight, plants build molecules of glucose (C6H12O6) and oxygen (O2). How do plants on Earth affect the amount of carbon in Earth’s atmosphere?5

• Plants decrease Atmospheric CO2

• Plants increase Atmospheric CO2

Which are typically products of photosynthesis?

• oxygen and carbon dioxide

• glucose and oxygen

• carbon dioxide and water

• water and glucose

Which correctly describes the purpose of photosynthesis?

• to release energy by decomposing glucose

• to use sunlight energy to make sugars

Which statement describes cellular respiration?

• the process of decomposing chemical energy stored in bonds into energy that can be used by the cell

• the process of combining oxygen and water to produce another substance to be transported

What are the products of cellular respiration?

• oxygen and ATP

• oxygen and carbon dioxide

• ATP, carbon dioxide, and water

• oxygen, glucose, and carbon dioxide

What is the chemical equation for photosynthesis?

• 5CO+7H2O→C6H12O6+6O2

• 6CO2+6H2O→C6H12O6+6O2

• 4O2+7H2O→C6H12O5+4CO2

A process by which plants use sunlight, water, and carbon dioxide to make sugars and oxygen is called?

• photosynthesis

• reproduction

• bonding

What organisms make their own food with sunlight or chemical energy?

• producers

• consumers

• decomposers

• scavengers

Cellular respiration is the process that releases energy by breaking down food molecules in the presence of oxygen.

• True

• False
