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.

Photosynthesis14

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.

Are You an Energy Master?

Before we take our Energy Quiz, lets see if you have what it takes to be called a Photosynthesis or Cellular Respiration Master! Click the links below, download the attached powerpoint, open in keynote and play the presentation. As you go through, click the appropriate boxes and answers to questions. If you can successfully get through the whole thing with no wrong answers, you are ready! Take as much time and as many tries as you need! Good luck!

Once you think you’ve Mastered all there is to know about Photosynthesis, try your hand at this game: Photosynthesis Master. 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!

Photosynthesis!

I know, I know I promised you a team building day. I promise (again) we will have it, just on monday so I can be there for it. Today, we’re going to learn all about photosynthesis!

If you remember, I told you a little about earlier this week. Stuff like: it takes place in the chloroplast, there are 2 reactions, the reactants, the products, etc.. We’ll today we’re going to go into a little more detail. I’m going to have you watch the video below and take some notes (make sure you use my notes handout because it has the pictures on it to make it easier to understand). Then on Monday, after the team building exercise, we’re going to make review posters for photosynthesis. I’ll show you what I mean then.

One last thing, next Friday we’re going to take the last of our common assessments. I’ll give you more info next week, but I wanted to make you aware and offer up the study guide (which is also available on the Bio: Semester 2 page). Have a great day and remember, after these notes… there’s only one more day of notes left the entire year!

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)
