I'm studing Cellular Respiration. We did a lab. We had technical difficulties... our CO2 gas sensor wasn't working properly. So I am curious, what trends SHOULD I have seen. We compared the CO2 output of bean sprouts vs mealworms. We tested at both room temp (27 degrees C) vs cold temp (15 degrees C) for both the mealworms and bean sprouts. I need to know the trends I should have seen, ie. does an animal or plant produces more C02 and why? Also does the the cool temp make the reduction in CO2 production? Thank you.

Scenario #3: Arsenic poisoning. Ralph worked in a zinc refinery for 30 years. He never missed a day’s work until about a month ago when he began to experience frequent headaches, long periods of confusion, with attendant severe diarrhea, and drowsiness. Arsenic inhibits the breakdown of pyruvate. 1. Which cellular respiration pathway is directly affected by arsenic poisoning? a. All cellular respiration pathways are affected b. Glycolysis c. Electron transport chain d. Kreb’s cycle 2. Which of the following cellular respiration processes will NOT be affected by the arsenic? a. Reduction of NAD+ and FAD during Kreb’s cycle b. Production of pyruvic acid c. Electrons will not be delivered to the oxygen to make water d. Creating an electrochemical gradient across the mitochondrial membrane
We often describe respiration by the simple equation of 6 O2 + C6H1206 - 6 CO2 + 6 H20. However, as we've now covered, there's way more going on than what's represented by this one equation. Summarize the entire process of energy generation starting from glucose, covering the substances produced through each process involved (no need to summarize the individual steps), where these processes take place, how they interact with each. other, changes in energy and oxidation along the way, and what happens to the molecules produced in the end.
