Summary Introduction
Introduction:
The Calvin cycle during photosynthesis involves the capturing of carbon from atmospheric carbon dioxide by using the energy of sunlight harnessed during light reactions. Calvin cycle starts and ends with the same five carbon molecule, ribulose bisphosphate (RuBP). This metabolic cycle is accompanied by carbon fixation, generation of glyceraldehydes-3-phosphate, and the regeneration of RuBP that facilitates the cycle to continue. Enzymes and energy carriers actively take part in the reaction of photosynthesis.

- Cells are open systems that exchange matter and energy with their surroundings. Which of the following best explains why plant cells require sunlight to make organic compounds, according to Gibbs’s theory of free energy? The photosynthetic reaction releases free energy to the surroundings. The photosynthetic reaction’s free energy is in equilibrium. The reactants of photosynthesis have less free energy than the products. The change in free energy (∆G) of the photosynthetic system is less than zero.arrow_forwardWhich of the following is TRUE about CAM photosynthetic pathway? Compared to the C3 and C4 pathways, CAM photosynthesis results in greater transpiration and water loss. O By separating where carbon is initially fixed inside the leaf tissue, CAM plants can better control the gradient of carbon dioxide between the air and their leaves. CAM photosynthesis is more energy efficient than C3 photosynthesis. Compared to C3 and C4 photosynthetic pathways, the rate of CAM photosynthesis is limited.arrow_forwardA botanist has been examining three plants, measuring the amount of acid in their cells and examining sections of their leaves under the microscope.

Rubisco, an enzyme found in plants, is critical to this process. How does the presence of rubisco affect the change in free energy consumed or produced by the reactants and products? The presence of rubisco increases the free energy produced by the reactants, but the free energy consumed by glucose stays constant. The presence of rubisco increases the free energy consumed by glucose, but maintains the free energy produced by the initial reactants. The presence of rubisco decreases the energy required for activation in the transition state and increases the free energy consumed by glucose. The presence of rubisco decreases the energy required for activation in the transition state, but the change in the free energy of the reactants and products remains constant.arrow_forwardChloroplasts contain chlorophyll and carotenoids. Chlorophyll directly absorbs light for use in photosynthesis. Carotenoids absorb light and transfer the energy from light to chlorophyll. The efficiency of photosynthesis varies with the wavelengths of the light that illuminates the chloroplasts. In an experiment to study the relationship between the incoming light wavelengths and the chemical reactions of photosynthesis using a species of green algae, a researcher labeled the CO2 supply to the algae with 14C, and the H2O with 18O. Which of the following results is expected? More 14C is found in the algae when it is illuminated by green light than when it is illuminated by blue-violet and red light. More 18O is found in the algae when it is illuminated by green light than when it is illuminated by blue-violet and red light. More 14C is found in the algae when it is illuminated by blue-violet and red light than when it is illuminated by green light. More 18O is found in the algae when…arrow_forward
- Consider the relationship between temperature and photosynthesis. As temperatures increase,gases such as CO2 diffuse faster. As a result, plant leaves will lose CO2 at a faster rate thannormal. If the amount of light reaching the leaf and the amount of water available are adequate,predict how this loss of gas will affect photosynthesis in the leaf.arrow_forwardDiagram 3: Light Wave Absorption of Chlorophyll a and b. Chlorophyll a Chlorophyll b 400 450 500 550 600 650 700 Wavelength (nm) Plant chlorophyll chemicals will absorb, or take in, light wave energy in order to produce their own organic molecules used for cellular energy. Reflected light refers to those wavelengths of light that will "bounce off" of the chlorophyll and not be absorbed. Select the conclusion that most accurately summarizes the data in diagram 3. Red and blue light waves have equal importance during photosynthesis. The majority of light energy is attained from red light, while the blue light waves provide additional light energy to photosynthesis. The majority of light energy is attained from blue light, while the red light waves provide additional light energy to photosynthesis. Medium length light waves are important to photosynthesis Absorptionarrow_forwardMost plants store excess energy from photosynthesis. Name some times when recovery of stored energy may occur. Does energy recovery always occur in the same sites where photosynthetic capture occurred?arrow_forward
- ATP is produced when protons (H+) flow down the gradient through the H+ channel/ATP synthase in the thylakoid membrane. A researcher discovers a drug that slows down the passage of protons through the H+ channel/ATP synthase. What is expected to happen if this drug is applied to the chloroplasts? The pH in the chloroplast stroma will increase, and less ATP will be produced. The pH in the chloroplast stroma will decrease, and less ATP will be produced. The pH in the chloroplast stroma will increase, and more ATP will be produced. The pH in the chloroplast stroma will decrease, and more ATP will be produced.arrow_forwardWhich of the following statements is FALSE? Water is the ultimate electron donor. Photosystem II has chlorophylls in its reaction center that has maximum light absorption at 680 nm. Plastoquinone has a higher reduction potential than plastocyanin. Proton gradient is created in the light phase of photosynthesis wherein the pH in the stroma is higher than in the lumen.arrow_forwardA group of scientists wants to test the effect of different wavelengths of light on plant photosynthesis. They have 3 treatment groups: red light, green light, and no light. They choose red light because chlorophyll has been shown to absorb red light. They choose green light because chlorophyll has been shown to reflect green light. They choose no light as a negative control to examine the rate of photosynthesis in the absence of light. To measure photosynthetic rate, the scientists use sensors to measure oxygen production of plants exposed to the different light treatments. Choose the best scientific hypothesis: O Photosynthesis is a critical process for plants, and it is of great importance that we understand how it is impacted by different wavelengths of light. O If rate of oxygen production is higher under red light than it is under green light or no light, it proves that red light has the largest effect on photosynthesis. O Because chlorophyll absorbs red light, rate of oxygen…arrow_forward
