of the claSS. 1. How do plants acquire the starting reactants of photosynthesis (CO, and H,O)? What do plants do with the products of photosynthesis (O, and carbohydrates)? 2. A plant may be using more energy to fuel life processes (cell respiration) than it is taking in through photosynthesis either because its cell respiratory rate is elevated or because photosynthetic rate is diminished. a. What is one potential reason why a plant may be forced to elevate its cell respiratory rate? b. What is one potential reason for why a plant may experience diminished photosynthetic rates? 65 1161_Ch_12_M....pptx
Put the steps for the formation and usage of ATP in photosynthesis in order. 1. Hydrogen ions will diffuse out of the thylakoid; the concentration of H+ ions inside the thylakoid is higher than outside. 2. ATP synthase adds a phosphate group to ADP to form ATP. 3. Potential energy is stored, so hydrogen ions can now diffuse out through protein channels in the thylakoid membranes.
Can someone help me understand this. Which of the following is NOT a product of the light reaction? carbon dioxide oxygen NADPH ATP energy intermediates Also, can you include information as to what are the reactants and products of photosynthesis?
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…
The primary role of the Calvin cycle in photosynthesis is to: - split H2O and release oxygen - establish a proton gradient across the thylakoid membrane - use the energy in ATP and NADPH to fix carbon and build sugars - produce ATP and NADPH 2. The enzyme used to catalyze the initial fixation of CO2 in C3 photosynthesis is: Rubisco NADP+ reductase ATP synthase PEP carboxylase 3. The primary role of the light reactions in photosynthesis is to: - bring CO2 into the chloroplast use the energy in ATP and NADPH to fix carbon and build sugars establish a proton gradient across the thylakoid membrane produce ATP and NADPH *I do not need an explanation so please don't provide, I just need an answer choice picked for each*
The figure shows the absorption spectrum for chlorophyll a and the action spectrum for photosynthesis. Why are they different? 400 500 600 700 Wavelength of light (nm) O Green and yellow wavelengths inhibit the absorption of red and blue wavelengths. O Oxygen given off during photosynthesis interferes with the absorption of light. O Other pigments absorb light in addition to chlorophyll a. Absorbance of chlorophyll a Violet Blue Green Yellow Orange Red - Rate of photosynthesis
The reactants of photosynthesis are... carbon dioxide + water + light (energy) O oxygen + carbon dioxide O oxygen +glucose O light (energy) + glucose + water
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

Light Reactions Dark Reactions Sugar Chloroplast Light ATP NADPH Calvin cycle NADP ADP Granum co. Figure 7.3. Processes of photosynthesis. The light reactions directly require light energy from the sun. The "dark reactions" are driven by the high energy electrons produced by the light reactions. The synthesis reactions happen in the daytime, but are sometimes called "dark" reactions because light energy is not directly required. What kind of energy is required to run the synthesis reactions? Where does that energy come from?
2. Sugar is made in the chloroplast through CO2 assimilation by the Calvin cycle. This cycle involves 11 enzymes and produces carbohydrates from atmospheric CO2 using NADPH and ATP supplied by the light reactions. Chloroplast phosphoglycerate kinase (cpPGK) catalyzes the conversion of 3-phosphoglycerate to 1,3-bisphosphoglycerate using ATP (step #2).
