Sketch an arrow to represent the direction that protons flow (via diffusion) through ATP synthase. c.

How would that affect ATP production from glucose?Aerobic respiration, used by the mitochondria of eukaryotic cells, is best represented by which of the following balanced equations? 6CO2 + 12H2S g C6H12O6 + 6S2 + 6H2O C6H12O6 + 6O2 + 6H2O g 6CO2 + 12H2O C12H22O11 + H2O g C6H12O6 + C6H12O6 6CO2 + 12H2O g C6H12O6 + 6O2 + 6H2O C6H12O6 + C6H12O6 g C12H22O11 + H2OIn biochemistry, the exergonic process ofconverting glucose and oxygen to carbon dioxide and water in aerobic metabolism can be considered the reverse of photosynthesis,in which carbon dioxide and water are converted to glucose andoxygen. Do you expect both processes to be exergonic, both endergonic, or one exergonic and one endergonic? Why? Would youexpect both processes to take place in the same way? Why?
- Which of the following statements concerning the complete oxidation of FADH2 in the electron transport chain is NOT true? a. In the final step, electrons from cytochrome c to O2 reducing it to H2O in complex IV, and four protons are transported from the intermembrane space to the matrix. b. In the first step, electrons from FADH2 are transferred in complex II to ubiquinone, which does not transport any proton across the inner mitochondrion membrane. c. In the second step, complex III transfers the electrons from ubiquinone to cytochrome c, and four protons are transported from the matrix to the intermembrane space. d. The complete oxidation of FADH2 causes transfer of 6 protons and yields two ATP.In chloroplasts, a greater pH gradient across the thylakoid membrane is required to power the synthesis of ATP than is required across the mitochondrial inner membrane. Explain this difference.Consider the structures and functions of mitochondria and chloroplasts. For each of the statements below, identify which part(s) of the chloroplast or mitochondrion (identified by letters in the figure below) are described. Some answers may include more than 1 letter. In those cases, separate the letters by a single space (eg. c g) Electron transport chains are located in ------ Photosystem I and II are located in ------- Ubiquinone is located in ------- NADPH is produced in ------ Pyruvate oxidation takes place in ------ ATP is produced in ------ NAD+ is produced in ----- High H+ concentration is produced in ----- O2 is produced in ----- RuBP is produced in ------

Which of the following does not correctly identify similarities and differences in the ETCs of these processes? a) Electrons delivered to the ETC are used to generate a proton gradient across the membrane b) In photosynthesis, the facilitated diffusion of protons across the membrane generates ATP and glucose molecules; in cellular respiration, this process generates ATP c) In photosynthesis, electrons are delivered to the ETC by NADPH; in cellular respiration, electrons are delivered to the ETC by NADH and FADH2 d) In prokaryotes, active transport moves protons across the cell’s plasma membrane during photosynthesis and cellular respirationPhotosynthesis is defined as the chemical process, wherein carbon dioxide in the presence of water and radiant energy gets converted to glucose (chemical energy), giving out oxygen as byproducts. In the equation, the combining reactants and resulting products are expressed along with their respective numbers of molecules. Putting this in a simplified formula, the following equation represents this process. CO2 + H2O + Light energy → C6H12O6 + O2 Considering this equation, how plant lovers (plantitos and plantitas) able to cultivate their plants?
