There are many similarities between the process of photosynthesis and the process of cellular respiration. Which of the following is an accurate comparison of photosynthesis and cellular respiration? Only cellular respiration involves an electron transport chain that creates a proton motive force driving ATP synthesis. Only photosynthesis involves redox reactions. The intermembrane space of mitochondria serves a similar function as the thylakoid space of chloroplasts. The Calvin cycle and the citric acid cycle have the same function.

Explain the reciprocal nature of the net chemical reactions for photosynthesis and respiration.
There are some similarities and some differences between the citric acid cycle in the mitochondrion and the Calvin cycle in photosynthesis. Which of the following is NOT a true difference between the two cycles? Both involve CO2, but in the Calvin cycle CO2 is used brought into the process as a source of carbon for the sugar being built. In the Mitochondrion, CO2 is removed from the sugar and leaves the cell. In the Calvin cycle, ATP is used to carry chemical energy from the light reactions to the the Calvin cycle where the chemical energy is incorporated in the sugar molecule that is being manufactured. In the mitochondrion, ATP is produced and brought out of the mitochondrion so it can provide chemical energy to the many activities going on in the cytoplasm The first step in the Calvin cycle, the carboxylation of RuBP, produces a 12-carbon product that splits into two 6 carbon pieces. In the first step of the citric acid…
Assume a thylakoid is somehow punctured so that the interior of the thylakoid is no longer separated from the stroma but the photosystems and membrane proteins of the electron transport chain are unharmed. This damage will have the most direct effect on which of the following processes?
After electrons are raised to high energy levels in photosystem II, they travel down an electron transport chain. As they are stepped down in energy, the lost energy is used to power which process. The pumping of high energy electrons into the intermembrane space. This creates a large difference in concentration and in electric charge between the intermembrane space and the lumen of the thylakoid. When these high energy electrons rush back into the thylakoid lumen, they are forced to travel through one of the ATP synthase molecules that sits embedded in the thylakoid membrane. ATP synthase uses the flow of hydrogen ions to phosphorylate ADP, converting it to ATP. The pumping of hydrogen ions into the stroma. This creates a large difference in concentration and in electric charge between the stroma and the lumen (watery interior) of the thylakoid. When When the hydrogen ions in the stroma rush back into the thylakoid lumen, they are forced to…
Photosynthesis and Respiration are opposing processes. One is required to produce food, the other to derive energy from food. Each of these processes involves a cycle to complete its goal. For Photosynthesis it is the Calvin Cycle; for Respiration it is the Krebs Cycle. Listed below are features of both cycles. Indicate which 5 of them are associated with the Calvin Cycle. Creates glucose ATP and CO2 are used ATP and CO2 are produced O A catabolic process An anabolic process. Oxidizes glucose O Occurs in mitochondria O Occurs in chloroplasts Occurs only in green organisms Occurs in all organisms
Please compare and contrast the light dependent reactions of photosynthesis and the electron transport chain in cellular respiration. You must describe all components of each pathway, including their purpose and location. In addition, you must discuss the electrons, their energy levels at each stage, what the extracted energy is used for, and what the final electron carrier/receptor is for each pathway
Which of the four stages of aerobic cellular respiration is most similar to the light-independent reactions oxygenic photosynthesis? Explain
Which of the following correctly sequences the steps of non-cyclic electron transport? * Water is oxidized by the capture of light energy; these excited electrons are passed through the dark reactions, returning to chlorophyll during the final light reactions The ATP and NADPH generated by the reactions of photosystem Il and photosystem I are utilized by the Calvin Cycle to build high energy glucose molecules Electrons donated from water molecules pass through photosystem I then O photosystem II before returning to the chlorophyll molecules, generating ATP in the process Chlorophyll molecules absorb UV radiation exciting electrons which flow through photosystem I, returning to the chlorophyll molecules ) This is a required question
Which of the following statements about photosynthesis is NOT true? Light independent reactions are very similar to the electron transport chain of cellular respiration Light is absolutely essential for both aspects of photosynthesis In order replace electrons, water is split to form oxygen gas Light dependent reactions are very similar, but in reverse, to the Krebs cycle and glycolysis
Which statement best describes translation? 00 The process converts an mRNA sequence into a polypeptide. It uses ribosomes to make mRNA. It produces Okazaki fragments. It produces RNA from DNA molecules The process breaks bonds between amino acids.
Which of the following statements is/are TRUE for photosynthesis? The e- moves from H20 to NADP+. Some of the products from the dark reaction are required in the light reaction. It is an exergonic process that naturally by using energy from light It Involves conversion of 02 to H20 and C02 to glucose.
Which of the following statements related to the Calvin Cycle is CORRECT? Six molecules of G3P are produced for every three carbon dioxide that undergo calvin cycle Carbon dioxide is attached to 3-phosphoglycerate resulting is 2 RuBP The regeneration of RuBP is important because it is directly used for the production of starch, cellulose, and glucose. One molecule of G3P exits the calvin cycle and five is used to form glucose for the production of starch, cellulose, and sucrose.
