Front

What is the main product of the Krebs Cycle?

Back

The main products of the Krebs Cycle are NADH, FADH2, ATP, and carbon dioxide.

Front

What is the role of NADH and FADH2 in cellular respiration?

Back

NADH and FADH2 are electron carriers that transport electrons to the Electron Transport Chain.
