Additional Resources

Cellular Respiration Introduction

Cellular Respiration Overview

 

 

Key Words

 cellular respiration, aerobic, anaerobic, mitochondria, cristae, intermembrane space, matrix, glycolysis, pyruvate oxidation, Kreb’s cycle, pyruvate, acetyl-CoA, coenzyme A, oxaloacetate, citrate, carbon dioxide (CO2)

 

As we look more closely at the reactions of cellular respiration, pay close attention to three things:

1. movement of carbon

2. movement of electrons

3. use or production of ATP energy

 

For cellular respiration you should be able to:

1.  Know the 4 metabolic pathways that make up cellular respiration.

2.  Explain each of the metabolic pathways that makeup cellular respiration with regard to:

     a.  how each reactant is used

     b.  how each product is generated

     c.  the destination of each product (what happens to each product?)

3.  Follow the release of energy (ATP and electrons) from glucose through each step of cellular respiration
