Transcript of 02.06 Introduction to Photosynthesis Light-Dependent Reaction : The energy releasing, light-dependent reactions of photosynthesis turn light energy into chemical energy. Which transfers this energy to ATP and NADPH, this then happens in the stacks of thylakoids of chloroplasts. ATP and NADPH are needed for the energy that is used in the light-dependent reaction.
a. Water boils to produce steam at 100 C (212 F) b. Water produces gas with sodium metal c. Water and oil separate when combined d. Water dissolves sugar 22. In the experiment, students put brine shrimp in water with different concentration of salt and counted the number. Which of the following changes to the experiment will increase confidence in the validity of the result? a. Count the number of dead brine shrimp instead of living brine shrimp b. Add more brine shrimp to the water with the highest salt concentration c.
A. Were the seeds in the “N” tube undergoing both photosynthesis and respiration, only photosynthesis, or only respiration? Use your results in Data Table 2 to support your answer. The seeds in test tube "N" underwent respiration. Respiration is always happening.
Then we observed them on different days describing them with qualitative and quantitative observations. Before the lab I expected the duckweed to show some sort of effect to the salt water because it is an indicator species.
Carly Crabtree Period 4 Accelerated Biology 11/20/15 Photosynthesis in Greenhouses Farmers use their knowledge about photosynthesis to increase crop growth every year. Greenhouse conditions are more easily controlled, rather than the air outside. Changing certain variables in the process of photosynthesis can change the outcome of the crops. One variable that farmers change is the temperature.
The process of photosynthesis is vital for the survival of most life on Earth. Without photosynthesis plant life would be unable to create its own food and sustain themselves causing them to die. Earth would lack the oxygen and energy that plant life provides. Producers are the main source of energy for living organisms because they can directly absorb light energy and turn it into chemical energy. Animals then eat the plants which give them a portion of that energy.
We accept our hypothesis of the germinated seeds in the dark and the dormant seeds in the dark having a higher rate of cellular respiration then germinated seeds in the light and the dormant seeds in the light. The germinated seeds in the dark had 0mL of change in oxygen levels while the germinated seeds in the light had -.05mL of change in their oxygen levels. The germinated seeds in the dark had a .05mL more for their change in oxygen then the germinated seeds in the light, therefore the germinated seeds in the dark had a higher rate of cellular respiration then the germinated seeds in the light. The dormant seeds in the dark had 0mL of change in their oxygen levels and the dormant seeds in the light had -.16mL of change in their oxygen levels. The dormant seeds in the dark had a .16mL greater change in their
photosynthesis and cellular respiration are extremely important in the cycle of energy to sustain life simply because nutrients would not metabolize in a productive manner. Both have numerous stages in which the process of energy occurs, and relationships with organelles located in the eukaryotic cell. Photosynthesis is a process by which green plant and other organism manufacture their food using sunlight to synthesize foods from carbon dioxide and water while cellular respiration is the oxidation of organic compounds that occurs within cells, producing energy for cellular processes. Photosynthesis occurs within organelles called chloroplasts. These organelles can absorb light, and are located inside of leaves.
Develop a hypothesis on the ability of your filtration technique to remove contaminants. Hypothesis = For this dirty water can be treated it will then be clean and drinkable water 2. Based on the results of your experiment, would you reject or accept the hypothesis that you produced in question 1? Explain how you determined this.
Energy is also needed to circulate blood, breath, take in oxygen, make new cells, grow, repair, and to transmit nerve impulses to react to changes in the environment. For example, moving quickly to get out of danger or recognising the best course of action to take in an emergency situation. Energy is also needed to build complex molecules such as enzymes and hormones from the simple molecules produced after we digest food and drink. A constant supply of energy is needed by the body and cells to enable all of these activities, and without this energy we would be unable to function as living beings.
Cell Respiration Lab Research Question What is the optimal temperature for germinating pea-seeds where the rate of respiration is the greatest? Background Information Cell Respiration refers to the biochemical process conducted by the cells of an organism that combines glucose and oxygen to produce energy in the form of ATP, along with two by-products, water and carbon dioxide. The equation representing this chemical reaction is shown below. C6H12O6 + 6 O2 6 CO2 + 6 H2O
My claim is photosynthesis does models the Law of Conservation of Matter and Energy because photosynthesis allows plants to store/reuse matter and energy. My first piece of evidence that supports the law of conservation of energy is when a bird eats a caterpillar then the bird gets the energy from the worm “so the bird indirectly gets the energy that began with glucose.” (Photosynthesis by ck-12 , n.d) My next piece of evidence is the sun's energy (light energy) is used to make the plants food glucose, which is the plant's energy, this shows the Law of Conservation of Matter because the light energy is transformed into something new which is the plant's food . (photosynthesis , n.d)
The Effect of Sugar Concentration on CO2 Production by Cellular Respiration in Yeast Introduction In this lab, our main focus was to find how sugar concentration affect yeast respiration rates. This was to simulate the process of cellular respiration. Cellular respiration is the process that cells use to transfer energy from the organic molecules in food to ATP (Adenosine Tri-Phosphate). Glucose, CO2, and yeast (used as a catalyst in this experiment) are a few of the many vital components that contribute to cellular respiration.
Cellular Respiration One of the main essentials of life that all organisms need in order to function in our world is, energy. We receive that energy from the food that we eat. Cellular respiration is the most efficient way for a cell to receive the energy stored in food. In cellular respiration, a catabolic pathway, which breaks down the molecules into smaller units, in order to produce adenosine triphosphate, also known as, ATP. ATP, is used by cells in the act of regular cellular operations, it is a “high energy” molecule.
Oxygen is released during the day and taken in at night through the stomata, which are small openings on the surface of the leaf. Oxygen is used to measure the rate of photosynthesis. The aim of this experiment is to observe the effect of light intensity on the rate of photosynthesis by seeing how many bubbles are
