If photosynthesizing plants are grown in thepresence of 14CO2, is every carbon atom of the glucose that is produced labeled with the radioactive carbon? Why or why not?
Based on the vein density results and your knowledge of how the light treatments would impact the light reactions of photosynthesis, how can you explain the high starch concentration and low photosynthetic capacity value in symplastic loader individuals grown in low light and transferred to high light for one week prior to the measurements? Figure Legend: Figure 1. Spinach is an apoplastic phloem loader, while pumpkin is a symplastic phloem loader. An experiment was performed where spinach and pumpkin individuals were grown under three conditions LL - in low light environment (grey bars) HL- in high light environment (white bars) LL->HL in low light environment and then transferred to a high light environment for one week prior to measurements (dark stripes bars) The following measurements were performed on individuals of the two species growing in the three different treatments: vein density, starch content in leaves, and photosynthetic capacity. Statistical tests were performed…
Melvin Calvin and Andrew Benson determined the steps in the light-independent reactions of photosynthesis by exposing the green alga Chlorella to CO2 labeled with the radioisotope carbon 14. By looking at which compounds the C14 ended up in, they were able to identify all intermediates in this cyclic pathway. Why did they predict correctly that the same set of intermediates would be formed in the light reaction in land plants?
In a photosynthetic investigation, a student measured the following pH of the stroma and the inner thylakoid compartments of spinach leaf cells at the conclusion of the experiment. Source of Fluid pH (mean) Standard Error of Mean (SEM) Stroma 8.2 0.75 Inner compartment of thylakoid 5.6 0.35 Explain the reason for the differences in pH between the stroma and the thylakoid lumen.
The chemical reaction equation for the conversion of ethanol (C2H5OH) to acetic acid (CH3COOH) is: C2H5OH + O2 → CH3COOH + H2OIn a vinegar production industry, acetic acid is produced from ethanol during the growth of the bacterium Acetobacter aceti, whose cellular composition is CH1,8O0,5N0,2. The biomass yield from substrate is 0.14 g/g, while the product yield also from substrate is 0.92 g/g. Ammonia is used as a nitrogen source. Based on this information, answer: (a) What is the oxygen demand for acetic acid production in this crop?(b) What are the cooling requirements of a bioreactor containing 3000 L of ethanol (ρ = 789 kg/m³), to be completely converted into acetic acid?
would you expect an absorption spectrum graph of chlorophyll (green plant pigment involved in photosynthesis) to be the same or not of that for the red food coloring? why?
using a 14CO2 fixation assimilation method,a plant is found to be fixing carbon at a rate of 140mgh-1 .dm-2 leaf area in the sunlight. In darkness the same plant is losing 30mgh-1.dm-2 . Calculate the photosynthetic capacity of the plant and state with reasons to which photosynthetic type the plant belongs
We perform our measurements for KHP at 281 nm. Would we get the same results for pathlength at 250 nm? What about using chlorophyll at 667 nm? Why might a too high concentration of KHP give erroneous data for measuring pathlength?
Three of the same species of plant are each grown under a different colored light for the same amount of time. Plant A is grown under blue light, Plant B is grown under green light, and Plant C is grown under orange light. Assuming the plants use only chlorophyll a and chlorophyll b for photosynthesis, what would be the predicted order of the plants from most growth to least growth? a. A, C, B b. A, B, C c. C, A, B d. B, A, C
The green color of plants is explained by the wavelengths of light that are reflected, transmitted, and absorbed by the chlorophylls in the thylakoids. Which of the following statements is true? Plants appear green because chlorophylls reflect and transmit yellow and green wavelengths of light, and absorb red and violet-blue wavelengths of light. Plants appear green because chlorophylls reflect and transmit red and blue wavelengths of light, and absorb yellow and green wavelengths of light. Plants appear green because chlorophylls reflect and transmit red and blue wavelengths of light, and absorb white wavelength of light. Plants appear green because chlorophylls reflect and transmit white wavelength of light, and absorb red and violet-blue wavelengths of light.

. Based on the data in the scatter plot, estimate the percentagechange in dry mass of corn and velvetleaf plants if atmosphericCO2 concentration increased from 390 ppm (current levels)to 800 ppm. (a) What is the estimated dry mass of corn andvelvetleaf plants at 390 ppm? 800 ppm? (b) To calculate thepercentage change in mass for each plant, subtract the massat 390 ppm from the mass at 800 ppm (change in mass), divideby the mass at 390 ppm (initial mass), and multiply by 100. Whatis the estimated percentage change in dry mass for corn? Forvelvetleaf? (c) Do these results support the conclusion fromother experiments that C3 plants grow better than C4 plantsunder increased CO2 concentration? Why or why not?
