Fill in the Blank

Fill in the blank: The enzyme responsible for generating ATP during electron transport is called ___ synthase.

Multiple Choice

Which of the following is the correct chemical equation for cellular respiration?

• C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP

• 6CO2 + 6H2O → C6H12O6 + 6O2 + ATP

• C6H12O6 + 6CO2 → 6O2 + 6H2O + ATP

• 6O2 + ATP → C6H12O6 + 6CO2 + 6H2O

Fill in the Blank
