BIOT 101 Lecture Handout 7 Aerobic Respiration and Photosynthesis Please refer to Biology , Solomon, Berg and Martin (your General Biology book) and your notes from BIOL 121 for the particulars of aerobic respiration and photosynthesis. You will be responsible for the information in these notes for the quiz and for the exam. Below is a brief discussion of the relationships between these two processes. I. Biochemically, aerobic respiration and photosynthesis are mirror images of each other. C 6 H 12 O 6 + 6 0 2 6 CO 2 + 6 H 2 O + Energy Aerobic respiration converts the energy stored in the bonds of glucose into high-energy ATP molecules while photosynthesis uses the energy of sunlight to create glucose molecules. Though aerobic respiration and photosynthesis appear to be doing exactly opposing reactions at the heard of these two pathways are two common processes: electron transport and chemiosmosis. These processes use the energy stored in high-energy electrons to synthesis ATP.

Unformatted text preview: In the case of aerobic respiration, it is the ATP that was the goal and the pathway stops there. In the case of photosynthesis, a set of reactions known as the “dark reactions” uses the energy of ATP to make glucose. A. In the eukaryotic cell, the mitochondrion is the site of aerobic respiration while the chloroplast is the site of photosynthesis. These organelles are similar in size and both have circular DNA that shows evidence of evolutionary relationship to bacterial DNA. B. In these two organelles the cytochromes that are responsible for electron transport and ATP synthase are embedded in membranes within the organelle. In the mitochondrion the cytochromes and ATP synthase are embedded in the inner membrane while in the chloroplasts, these components are found in the membrane of the thylakoids.
