This resource turns cellular respiration in consumers into a complete, ready to use review for Grade 9-12 biology, covering the same NGSS standard from three different angles.

The set includes questions like "What is the main purpose of the electron transport chain?", "Which energy-rich molecule is generated during the final stage of cellular respiration?", and "What is produced during the Krebs cycle?"

What's Inside?
