Cellular Respiration, although the inputs and outputs seem easy, the process is very convoluted 
and complicated. Lucky for you, we’re going to simplify it to a point that is appropriate for a High School Biology student.
Keep in mind that Photosynthesis & Cellular Respiration are reciprocal reactions. What that means is that the requirements of Cellular Respiration are the products of Photosynthesis! Likewise, the products of Cellular Respiration are the requirements of Photosynthesis! Its a 3 Billion year long symbiotic relationship! (And you thought your month-long high school girlfriend was a long-term commitment!)
Here is the jist of what Aerobic (meaning with Oxygen present) Respiration entails…
Glycolysis
- Uses 2 ATP to break down Glucose
- NADH & 4ATP (net gain +2 ATP) are created.
- The NADH goes to the Krebs Cycle.
Krebs Cycle
- Uses Oxygen and Acetyl-CoA
- Makes 2 ATP, NADH, & FADH2 (both of which are electron carriers)
- Carbon Dioxide is given off as a byproduct.
- The NADH goes on to the ETC
Electron Transport Chain
- Uses Oxygen and NADH
- Make 32 ATP and Water (used as an electron acceptor)
Photosynthesis may seem like an easy topic, based on what you learned in middle school. But, as we go a little deeper into the processes of how Plants chemically create glucose from a gas, a liquid, and sunlight we find that it is a whole lot more interesting and complicated.

Below is a graphic organizer to show the parts of the chloroplast, the reactants, the products, and the important molecules involved in both the Light & Dark Reactions.
