Describe the changes you would expect to see to this graph if the population of cyanobacteria increased dramatically in the ocean water surrounding Hawaii in 2003. Explain your predictions. -If the population of cyanobacteria were to dramatically increase in that certain area, the amount of carbon dioxide would decrease and the amount of oxygen would increase. That means there will no longer be an issue for respiratory breathers. If the cyanobacteria kept taking away carbon dioxide, it would
I will do this by counting the number of bubbles that are released, as they are a product of the process of photosynthesis. Hypothesis: I believe that too little light wont be enough for photosynthesis and too much might cause the plant to overheat or some for of “shutting down”. IV: The light intensities, done by putting the light source at different distances to the elodea plant (12.5 cm, 25 cm, 37.5 cm, 50 cm, 62.5 cm, 70 cm) DV: The DV is the number of bubbles that rise to the top of the test tube. Control: The first trial, where the elodea plant is under the lights in the room with no
Describe how you carried out your investigation? 1) Add 10cm³ of hydrogen carbonate indicator to each of the 5 boiling tubes 2) Select 5 pond weed shoots of the same length 3) Put pond weed shots in the boiling tube and cover with bong 4) Set boiling tubes up at 20,40,60,80 cm away from your light source 5) Look at the colour of the indicator at 30 minutes 6) convert the colour to PH using a PH spectrum 7) As Co2 is more acidic the more Co2 is used the higher the PH will rise In other words the more photosynthesis the higher the PH. What did you change in your experiment? The light intensity by changing the distance from the lamp What did you keep the same? Why?
Name: Alexis Savastano How Does pH Affect an Enzyme? Catalase is an enzyme that helps decompose the toxic hydrogen peroxide that is produced during normal cell activities. The products of this reaction are water and oxygen gas. The pressure of the oxygen gas in a closed container increases as oxygen is produced. Any increase in the rate of reaction will cause an increase in the pressure of the oxygen.
This would lead to wells drying up. Another factor affecting water supply is climate change. As climate warms up weather patterns are shifting. Some places experience a decrease in rainfall and others see an increase. A decrease in rainfall means there is less water in aquifers and the water table.
When you have relaxed hemoglobin, you’ll usually have a higher Ph, along with a lower CO2. This state favors the oxygen attaching to the hemoglobin. Once the oxygen attached, the hemoglobin will become tense, and the entire structure will undergo a sligh change in shape. The color of the hemog;obin will also become a ruby or brilliant red. When Hemoglobin releases oxygen As the hemoglobin travels, it will encounter places when the Ph is lower, and the CO2 is higher.
The Action Spectrum and the Absorption Spectrum Introduction: The purpose of this experiment is to learn the rates of photosynthesis under different lights, and the absorbance of photosynthetic pigments in spinach extract. “There would be no biology without photosynthesis. Plant biomass is the food and fuel for all animals. Plants are the primary producers. These amazing organisms are capable of capturing the energy of sunlight and fixing it in the form of potential chemical energy in organic compounds.” (Measuring the rate of photosynthesis) “Light is one of the main factors that affects the rate of photosynthesis, which literally means using light to create something new.” (What Are Three Factors That Affect the Rate Which Photosynthesis Occurs?)
Conclusion Throughout this lab, my partners and myself were searching to prove how much the different increments would affect the oxygen production. In my hypothesis, I explained that more oxygen would be produced with more hydrogen peroxide, because the catalase enzyme would have more hydrogen and oxygen liquid, for the catalyst to create water and oxygen. Once the catalase doesn’t have anything to break down, it takes for time, and eventually stops, because there are no more reactants. In our results, we had three concentrations that produced 100 cm3 of O2 and the two others, reached the time limit of 6 minutes, 360 seconds, and weren’t measured regarding time. I noticed that all the numbers were in a very close range during all five trials, and none of them had outliers.
New York,, NY: Chelsea House Publishers. In the example of photochemistry, which is the branch of chemistry concerned with the chemistry effects on lights, photosynthesis works the same way. With the progression of pigmentation needing light, without this molecule, the principle of photochemistry would not be able to absorb any wavelengths. Photosynthesis works the same way. Absorption through light, the development of chlorophyll sets in motion the process of a rapid (photon) pigmentation state, allocating energy to an electron from the chlorophyll molecules .Compatible energy from the photon transfers itself from the atom within the head of the
Gabriella Armstrong An Experiment Investigating the Rate of Photosynthesis in a Water Plant Introduction Photosynthesis is the process in which carbon dioxide and water are converted into glucose and oxygen. The reaction requires light energy, which is absorbed by chlorophyll. This process can be represented using an equation: Carbon dioxide + Water (+ light energy) → Glucose + Oxygen Research Question The objective of the experiment was to find out if light intensity affects the rate of photosynthesis in aquatic plants that are naturally found in water. This would be observed by the amount of oxygen bubbles released in water during photosynthesis. By shining a light at different distances to the Elodea plant a trend may be observed between light and the rate of photosynthesis.
