Concept explainers

Photosynthesis

Plants have a capacity that we humans can only imagine— the ability to produce food from sunlight. Sure, we can prepare some dishes that we can savor on, but it become possible because of the plants (as they serve as a producers of all the raw materials required). Photosynthesis is the method of assembling carbohydrates with the aid of sunlight.

Which of the following substances does not participate in the Calvin-Benson cycle? a. ATP c. NADPH e. PGAL b. O2 d. RuBP f. CO2
Draw a diagram of the dark phase of photosynthesis. You must represent this phase in the form of a cycle indicating the parts of carboxylation, reduction, generation of hexoses and regeneration. Ribulose, CO2, rubisco, phosphoglycerate (PGA), bisphosphoglycerate, phosphoglyceraldehyde (PGAL), ATP, ADP, NADPH, NADP, kinase, fructose, and glucose should appear.
Which of the following statements about the challenges of C3 photosynthesis under hot conditions is TRUE? O When they close stomatal cells, they save water but lose too much O2. O Rubisco has a higher affinity for CO2, making the rate of photosynthesis too rapid. When stomatal cells close, photorespiration increases and CO2 is lost. C3 plants have to spend energy to store carbon in a separate specialized cell.
Which of the following statements about the light reactions of photosynthesis are correct? 1. Absorption of light does one thing: it makes chlorophyll easier to oxidize. 2. In PSII, the rate of damage to the D1 protein can never exceeds the rate of repair. 3. Electron transport is spontaneous (exergonic) as electrons move from P680* to P700+. 4. Compared to anoxygenic photosynthesis, in oxygenic photosynthesis less light needs to be absorbed to reduce NADP+. A. 1,2 and 3 B. 1 and 3 C. 2 and 4 D. 4 only E. All of 1,2,3 and 4 are correct
Identify the correct compound to create a chemical equation that represents Photosynthesis. + Drag and drop the right reactants and products of the Light Dependent and Light Independent (aka Dark) Reactions. Chloroplast NADPH NADP+ ADP Water - H20 Calvin Cycle Glucose - C6H1206 ATP Light Reaction Thylakoids Stroma O2 Carbon Dioxide CO2 Identify the reactants and products that are used and given off by plants and animals.
What is the overall outcome of the light reactions in photosynthesis? NADPH and ATP molecules are produced during the light reactions and are used to power the light independent reactions. NADPH and ATP molecules are produced during the light reactions, which are used to power the light dependent reactions. Sugar and ATP are produced during the light reactions, which are used to power the light independent reactions. Carbon dioxide and NADPH are produced during the light reactions, which are used to power the light dependent reactions.
Cells are open systems that exchange matter and energy with their surroundings. Which of the following best explains why plant cells require sunlight to make organic compounds, according to Gibbs’s theory of free energy? The photosynthetic reaction releases free energy to the surroundings. The photosynthetic reaction’s free energy is in equilibrium. The reactants of photosynthesis have less free energy than the products. The change in free energy (∆G) of the photosynthetic system is less than zero.
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.
Plant chloroplasts are able to generate which of the following organic product molecules during oxygenic photosynthesis? carbon dioxide water diatomic oxygen glucose hydrogen sulfide
Photosynthesis is a complex process. Two main stages of photosynthesis are: H20 co 1 Light dependent reactions This step converts light energy to chemical energy. Light NADP 2 Calvin Cycle Also known as the light independent reaction. In this stage, CO2 is taken up by one of the molecules in the cycle. ATP and NADPH reduce CO2 to a carbohydrate (G3P). ADP LIGHT CALVIN REACTIONS CYCLE Thylakoid Stroma NADPH 1. Inside of the chloroplast, chlorophyll molecules absorb light and convert light energy to chemical energy. In what stage of photosynthesis is chlorophyll needed? Why? Chloroplast (CH20] (sugar) 6 CO2 + 12 H20 + light energy → CeH12O6 + 6 O2 + 6 H20 carbon dioxide + water + light energy > glucose + oxygen + water 3. What are the inputs/ reactants for Calvin cycle? 2. What are the two outputs/ products of light dependent reactions?
Carbon fixation during the light-independent reaction of photosynthesis obtains its carbon atoms: from water molecules only from carbon monoxide molecules only from H2O molecules only from carbon dioxide molecules only from CO molecules only
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
