Why does cyanide inhibit electron transport but not photosynthesis?O In animals cyanide binding to complex IV blocks electron transport and therefore ATP synthesis, in photosynthesis thiscomplex has other hemes that cyanide cannot bind and therefore is not inhibited.O In animals cyanide binding to complex IV blocks electron transport and therefore ATP synthesis, in photosynthesis thiscomplex is not used and therefore is not inhibited.O In animals cyanide binding to complex IV prevents hydrogen gradient formation and therefore ATP synthesis, inphotosynthesis this complex is not used and therefore is not inhibited.O In animals cyanide binding to complex IV blocks electron transport and therefore ATP synthesis, in photosynthesis usesmultiple complex IVs that cyanide cannot bind and therefore is not inhibited.

What would be a likely consequence if step 4 of the citric acid cycle no longer operated far from equilibrium, and instead occurred near equilibrium? the step would need to be coupled to ATP hydrolysis none of these possibilities are likely this step would no longer be a highly regulated step the reaction would no longer occur
How is does oxidation-reduction play an important role in electron transport chain? In what way is electron transport an example of a biological battery? Give two unique features of the ATP Synthase and explain its significance in making ATP.
The citric acid cycle occurs outside the mitochondria. Group of answer choices True False From a plant's perspective, the main purpose of photosynthesis is to Group of answer choices to produce sugars and oxygen for heterotrophs. plants are not cognitive organisms and therefore we have no idea what the "purpose" of photosynthesis is for the plant. to produce enough O2 gas for the plant to survive through the night. make sugars, such as glucose, to use for building cell walls and for energy needed by the plant. The main purpose of the light reactions in photosynthesis is Group of answer choices to take the high energy electrons out of glucose. to generate ATP and NADPH to send to the Calvin Cycle. to produce all the ATP the plant cell needs for its cellular work. to produce enough oxygen gas for humans to survive. The actual process of making sugar in photosynthesis occurs during the Calvin cycle. Group of answer choices True…

Like many fruits, apples contain not only fructose and glucose, but also sucrose, a dimerof fructose and glucose. Synthesizing sucrose is endergonic and so not spontaneous. Onerole of ATP is to facilitate reactions that would not occur spontaneously. The threephosphate groups are electron rich and tend to repel each other. Therefore, ATP is a bitlike a compressed spring, ready to kick off one phosphate group releasing energy.Consider: Fructose + glucose --> Sucrose delta G= 6.4 kcal/mol ATP --> ADP + Pi delta G= -7.3 kcal/mol a. Draw a simple energy diagram (including the relative energy of the reactants andproducts) that shows why the sucrose synthesis reaction doesn’t occur spontaneously. b. How could having these two reactions occur at the same time help with sucroseproduction? c. Draw the energy diagram that shows all the reactants and products for the combinedreactions. d. What is delta G for the combined reactions? e. Name a few of the biological processes in the body that…
