WHAT IF? Write an equation that uses the products ofphotosynthesis as reactants and the reactants of photosynthesis as products. Add energy as another product.This new equation describes a process that occurs in yourcells. Describe this equation in words. How does thisequation relate to breathing?
Why do plant leaves look green to us?
1. Because pigments in chloroplasts absorb green light, while red and blue light is reflected
2. Because pigments absorb red and blue light, while the green light is reflected
3. Because pigments absorb red and blue light and green light is emitted from their excited states
4. Because pigments in chloroplasts absorb green light, while red and blue light passes through the leaf
Can someone help me understand how to calculate the rate of photosynthesis?

- How are the NADPH and GA3P molecules made during photosynthesis similar? They are both end products of photosynthesis They are both substrates for photosynthesis They are both produced from carbon dioxide They both store energy in chemical bonds.arrow_forwardWhich of the following components is nor used by both plants and cyanobacteria to carry out photosynthesis? chloroplasts chlorophyll carbon dioxide waterarrow_forwardFigure 8.18 Which of the following statements is true? In photosynthesis, oxygen, carbon dioxide, ATP, and NADPH are reactants. G3P and water are products. In photosynthesis, chlorophyll, water, and carbon dioxide are reactants. G3P and oxygen are products. In photosynthesis, water, carbon dioxide, ATP, and NADPH are reactants. RuBP and oxygen are products. In photosynthesis, water and carbon dioxide are reactants. G3P and oxygen are products.arrow_forward
- 1. Look at the molecular formula for plant tissue. Where does the carbon come from? 2. Where does the hydrogen in C6H12O6 come from? 3. When radioactive isotopes of oxygen atoms are put into CO2 molecules and the plant is allowed to photosynthesize, only new plant tissue (C6H12O6) is radioactive and the oxygen gas given off is not radioactive. Draw a dotted line in the photosynthesis equation to show where the oxygen atoms in CO2 go. 4. Draw a dotted line in the equation to show where the oxygen atoms in H20 go.arrow_forwardHi, I am doing a question on photosynthesis and I have a question about the answer that was provided. The question states: If four molecules of CO2 enter the Calvin cycle, how many molecules of G3P are produced, and how many molecules are exported? I know that each turn makes 2 G3P so it would make 8 molecules. When I read the book it said that 3 turns makes 6 and then 1 is exported, so why does 4 turns make 8 and 4 be exported?arrow_forwardNull hypothesis If the Hydrilla plant is placed in light conditions, then it will undergo photosynthesis and respiration. If the Hydrilla plant is placed in dark conditions, then it will undergo only respiration. The Hydrilla plant will undergo photosynthesis and respiration when placed in light conditions. The Hydrilla plant will undergo respiration only when placed in dark conditions. Determine the Independent and Dependent variablesarrow_forward
- Photosystem II uses sunlight to strip electrons (and protons) away from which of the following substrate molecules (in the chloroplasts of green plants and green algae)? C6H12O6 only C6H12O6, H2O, and CO2 only CO2 only H2O and C6H12O6 only H2O onlyarrow_forwardBased on the graph below, what can you infer? Absorption and Action Spectra 400 500 600 700 Wavelength of light (nm) photosynthesis is most active between 400- 475. That is why plants are green photosynthesis is most active between 450 -550. That is why plants are green photosynthesis is most active between 600- 700. That is why plants are green both a and c are correct There is not enough evidence in the graph to infer any of the above Absorbance / Photosynthetic Ratearrow_forwardР Question 30 With your help, the bus arrives at the starting point for photosynthesis. You look at all the activity here - there's so much going on! Something looks a bit off though. Ms. Frizzle announces to everyone: "Keep your hands inside the bus everyone! I was told this tree has been treated with a chemical that shuts down Photosystem I." That makes sense with what you're seeing, you think. What do you see happening at Photosystem I? Or more to the point, what do you NOT see happening there? D Edit View Insert Format Tools Table 12pt v Paragraph P Р Question 31 The bus donast BIUA 2 T² هی 固v v 固v く く描く To 田 I √xarrow_forward
- What two main products result from photosynthesis? oxygen and carbon dioxide chlorophyll and oxygen sugars/carbohydrates and oxygen sugars/carbohyd rates and carbon dioxidearrow_forwardCan someone help me understand this. A student set up an experiment to show the effect of light color on photosynthesis in Elodea plants. She filled two test tubes with distilled water and placed a piece of Elodea in each of the tubes. She added a drop of phenol red, which turns red in a basic solution and yellow in an acidic solution. She blew in each tube before placing the volumeters on the top of the tube. Why did she blow into the tube? to add oxygen to the tube to add carbon dioxide to the tube to add carbohydrates to the tube to add sodium bicarbonate to the tubearrow_forwardIn photosynthesis, reaction? which of the following is NOT true about the light-dependent ("light”) Light-excited electrons in chlorophyll provide the energy for ATP production None of the other four answers (All are true of the light-dependent reaction) The light-dependent reaction converts light energy to chemical energy stored in ATP The light-dependent reaction (non-cyclic) captures electrons in NADPH Glucose is synthesized from CO2 and water during the light-dependent reactionarrow_forward
