volume_mute

True or False: The development of the Krebs cycle increased the total number of ATPs that could be produced from glucose breakdown to 38.

True

False

Correct Answer

True

Explanation

Before the Krebs cycle evolved, organisms relied only on anaerobic glycolysis. The addition of the Krebs cycle and oxidative phosphorylation raised the potential ATP yield per glucose molecule to as many as 38.
