Many commercial herbicides act by inhibiting photosynthetic electron transport. They are investigating three herbicides for potential inhibitors of photosynthetic electron transport. a) How can you determine whether these substances have an inhibitory effect on photosynthetic electron transport? How can you quantify the effect? b) An inhibitor has produced a strong effect in "in vitro" tests, but the effect is significantly less in "in vivo" tests. What can be the reason for the reduced effect "in vivo"?

What is the action spectrum? Question 15 options: a graph plotting a pigment's light absorption vs. wavelength a profile of the relative effectiveness of different wavelengths in driving photosynthesis the wavelengths of the electromagnetic spectrum that are visible light
HIGH SCHOOL BIOLOGY QUESTION - please provide a junior/senior high school level response. Compare and contrast the electron transport chain in the mitochondrion v.s. chloroplast in terms of the electron carriers used to "drop off" electrons, the direction of H+ pumping, the creation of an electrochemical gradient, the synthesis of ATP, the final electron exceptor, etc. How are they similar? How are they different?
In this question, I'd like you to think about what would happen if we applied an herbicide that prevented plant growth by inhibiting some of the pieces in your diagram above. For example, if we applied an herbicide to our plants and it affected the ability of Photosystem II to work, it would prevent he production of oxygen. Let's say we apply an herbicide to our plants and it affects the function of ATP synthase. What product would be inhibited? Group of answer choices ATP NADPH G3P Oxygen
The light-dependent reactions include an electron transport chain system that works in a very similar fashion to the electron transport chain in respiration. In complete sentences, briefly describe how this system works and what job it performs in the light-dependent reactions. (Your answer should include a discussion about concentration gradient.)
The compound Carbonyl cyanide-p-trifluoromethoxyphenyl hydrazone (FCCP) acts as an uncoupler of electrochemical gradients (in both mitochondria and chloroplasts) by shuttling protons across membranes. Predict the effect of a high dose of FCCP on the synthesis of ATP and NADPH in photosynthesis. Rationalize your answersAnswer separately with prediction and reason please thank you so much
Which of the following statements are correct? Explain your answers.A. Many, but not all, electron-transfer reactions involve metal ions.B. The electron-transport chain generates an electrical potential across the membrane because it moves electrons from the intermembrane space into the matrix.C. The electrochemical proton gradient consists of two components: a pH difference and an electrical potential.D. Ubiquinone and cytochrome c are both diffusible electron carriers.E. Plants have chloroplasts and therefore can live without mitochondria.
A mutant form of an Arabidopsis thaliana plant has defective chlorophyll production, such that the abundance of chlorophyll molecules in chloroplasts is 5% the normal level, and the chlorophyll molecules are on average too far apart for resonance energy transfer to occur. What will be the effect on the overall efficiency of photosynthesis in the plant? Rationalize your answer
