Cellular Respiration

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…

 

Aerobic Respiartion

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

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.

Light Reaction

  • Light & Water enter the Thylakoid (or granum)
  • Oxygen is released as a byproduct
  • In the process, NADPH and ATP are charged and carry energy to the Dark Reactions.

Dark Reactions

  • The ATP and NADPH, combined with Carbon Dioxide, create Glucose.
  • The leftover NADP+ and ADP go back to the light reaction.

Open the document in Powerpoint or Keynote, start the presentation, then click on the boxes with the correct answers to the questions. See if you can make it all the way through without a wrong answer… if you can you will be the Photosynthesis Master!
