Introduction:
The study of energy and its conversion to one form into another (transformation) is called thermodynamics. The term thermodynamics correlates between heat, work, energy, and temperature. There are three laws in thermodynamics: the first law of thermodynamics (law of conservation of energy), the second law of thermodynamics, and the third law of thermodynamics.

the question is:
Start with a photon of sunlight and a carbon atom in a molecule of carbon dioxide in the atmosphere: model/diagram their pathway from that starting point to their final destination as a glucose molecule that is used for energy in a cell in the plant root. Following your diagram/model, provide a written explanation for what your diagram/model depicts. Make sure both your model and explanation are clear, concise, and have the appropriate level of detail to clearly demonstrate you understand photosynthesis, cellular respiration, and the movement of mass and energy in plants.
my ans:A glucose particle is continuously mellowed into CO2 and water during cell breath. Some atp is created straightforwardly during the responses that change glucose. Nonetheless, undeniably more ATP is created later in a cycle known as oxidative phosphorylation. Glycerol is changed over into one of the glycolysis moderate items and hence enters the cell breath pathway. Unsaturated fats go through…

Why might that be?arrow_forwardSuppose that you are measuring CO2 exchange by a leaf. During the time period of your measurement, 1.10E+7 molecules of glyeraldehyde phosphate (PGAL) are made from CO2 in photosynthesis and 4.00E+6 molecules of glucose are used in cellular respiration.

Your flowchart should include these concepts and details: • location in the organelle the reactions occur, • the type of biochemical reactions or cellular transport, • the substrates and products for the overall process, • vocabulary and terminology that allow you to demonstrate your understanding. Ask yourself these big questions as a way to monitor and improve your work: • Is the information I have presented a complete representation of my learning? • Is the information I have presented correct? • Have I fulfilled the requirements of the task? • Are the steps I describe organized in the correct order?arrow_forward
- A team of researchers investigated the effects of phosphorous availability and light intensity on an angiosperm species. Seeds of the angiosperm were divided into four equal groups. Groups 1 and 2 were exposed to 200 µmol, and Groups 3 and 4 were exposed to 500 µmol. Groups 2 and 4 also received a phosphorous (P) solution. After 20 days, all plants were weighed, and the average dry weight of each group was calculated. The results are in the table below.

Your experiment should directly relate to the processes of cellular respiration and photosynthesis and show a clear understanding of how those two processes impact energy transfer at a global level.arrow_forwardCody is trying to explain to Sarah that one advantage enjoyed by plant cells is that they do not need to bring CO2 in from the environment for photosynthesis. He says, “They can simply grow by using the CO2 generated from cellular respiration”. How should Sarah respond? A. YES! This is a great example of thermodynamic equilibrium, or balance. B. YES! Since CO2 will move rapidly from mitochondria to the chloroplast. C. NO! To grow, the cell must fix more CO2 than it releases through respiration. D. NO! Most plant cells do not photosynthesize and respire at the same time.arrow_forward
