Check for Understanding the Krebs Cycle (and intermediate step)

The Krebs cycle is a biochemical pathway, this is the reactant to this process or the beginning compound to start it:

• ATP

• acetyl-CoA

• Carbon dioxide

• all

This process requires oxygen, a aerobic process:

• Krebs cycle

• Glycolysis

• True

• False
