photosynthetic rate. Photosynthesis at low temperatures actually take CO2 more efficiently. The rate of photosynthesis is decreased by higher oxygen concentrations. Lower temperatures inhibit Rubisco and forces this enzyme to to work competitively. Rubisco works competitively because is actually binds itself to oxygen rather than binding to carbon dioxide because of the mere attraction. Therefore‚ in doing so‚ this activates photorespiration rather than photosynthesis. Photosynthesis in corn is different

BIO 101 Lecture Notes for Respiration‚ Fermentation‚ and Photosynthesis Respiration During aerobic respiration‚ glucose is completely oxidized (all H’s removed) leaving CO2 as an endproduct. The H’s are taken by coenzymes (NAD and FAD) to the electron transport chain. There the energy is drained from the hydrogen electrons and the energy is used to make ATP. The H’s are ultimately accepted by O2 to make H2O as an endproduct. Respiration occurs in three major stages: 1) Glycolysis

reasonably be expected to affect the outcome. For example‚ in the investigation “How does the speed of movement of chloroplasts in Elodea cells vary with light intensity?”‚ the student must state clearly that the independent variable is the light intensity and the dependent variable is the speed of movement. Relevant controlled variables would include temperature‚ preparation of Elodea cells‚ sample size and light quality

Associate Program Material Cell Energy Worksheet Answer the following questions: Cellular respiration: • What is cellular respiration and what are its three stages? Cellular respiration is the set of the metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP)‚ and then release waste products. The reactions involved in respiration are catabolic reactions that involve the redox reaction

respiration and oxygenic photosynthesis are two cellular processes that have evolved in similar ways. Cellular respiration is responsible for the process of ATP‚ meanwhile oxygenic photosynthesis is the process of turning light energy into food. It is evident that both of these processes have their own reactants‚ products‚ and biochemical pathways. Both of these processes have evolved from their primitive original state‚ but it is important to understand that oxygenic photosynthesis evolved before aerobic

red light‚ we predicted that juniper needles placed in blue light would photosynthesize faster than juniper needles placed in red light. We measured the rate of change in CO2 concentration due to juniper needles. For each sample‚ we placed the needles into a chamber connected to the CO2 monitor and measured the rate of change of CO2 concentration for 10 minutes under red light and then 10 minutes under blue light. We ran three independent trials and alternated which color of light to which the leaves

- Cellular Respiration Assignment - 1. What two molecules are formed when a phosphate is removed from ATP? There are three phosphate groups in ATP molecule (Adenosine Triphosphate)‚ when removing one phosphate molecule‚ ADP molecule is formed (Adenosine Diphosphate). 2. What is the function of ATP? Describe the molecule. The function of ATP is storing energy within a cell. ATP is adenosine triphosphate‚ C10H16N5O13P3‚ a high energy complex‚ giving the necessary power to push metabolistic

between Carbon Dioxide [CO2] breathing plants and Oxygen [O2] breathing life forms. All oxygen-breathing life forms take in Oxygen and exhale CO2. Plants take in the CO2 and use it in their photosynthesis process and in turn give off oxygen. The Carbon Dioxide-Oxygen Cycle is a continuously occurring process whereby animals inhale Oxygen and then exhale carbon dioxide‚ and plants use the CO2 and "exhale" O2. Plants and other producers use carbon dioxide in photosynthesis. They produce oxygen as a
