The panel that converts light energy into electrical energy is called a Photovoltaic panel. Light energy is not only used industrially and privately, but some of our vehicles run on part solar electric or entirely on solar electric. The light energy is collected through a panel on the vehicle, which is transferred to electrical energy that hits the motor; the motor then converts the electrical energy into mechanical energy, which turns the drive shaft that turns the wheels (kinetic energy). Not all energy transfer is perfect, there will always be a loss of energy in any system. The loss of energy will come from the electrons passing through any wires, released as heat energy.
The role of the of the electron transport system is to turn the electrons given off from the other two processes and turn them into ATP. This process makes the most ATP in relation to the previous processes. This all happens within the mitochondria. Photosynthesis: • What is the overall goal of photosynthesis? To turn light into energy.
Nanotechnology In my interview with Kevin Hennessey from the California Nanoscience Institute here at UCSB, he explained about the research of compound semi-conductors. His work is engrossed in Nanoelectronics which involves the exploitation of quantum behavior in nano-scale systems. Compound semi-conductors differ from the traditional silicone based devices and offer superiority. (Hennessey Interview) Development of compound semi-conductors requires the use of technologies on nano-level, one billionth of a meter. "Scientists and companies are envisioning dramatic advancements in the functionality and properties of materials, including improved strength and durability.
The chloroplasts are protected and contained by a membrane, but they are close to the surface of the cell to catch the maximum amount of light. Their broad length also allows larger wavelengths of light to be absorbed. The energy absorbed is transferred to electrons and excites them to a higher energy level. This leads to the photolysis of water which results in the formation of hydrogen ions, electrons and oxygen gas. The electrons formed during photolysis then replace those excited by the light.
Purpose To demonstrate that CO2 is used during photosynthesis. To demonstrate that CO2 is produced during cellular respiration. III. Hypothesis 1. If we put elodea, bromthymol blue, seltzer water, and regular water in a vial in the sunlight then we can demonstrate that carbon dioxide is used during photosynthesis because the indicator will turn blue.
A slower process than MIG, it produces a more precise weld and can be used at lower amperages for thinner metal and can be used on exotic metals. TIG does require quite a bit more time than MIG to learn. It is similar in technique to gas welding. TIG can be used with pure helium or argon as an inert shielding gas to protect the weld pool from the atmosphere. (Nitrogen, hydrogen, oxygen, carbon dioxide, and other elements cause weld defects if introduced to the weld pool.)
The reaction center contains chlorophyll a. The role of pigments is to catch the wavelengths of light. In Exercise 4B, the function of DPIP will be reduced when light strikes the chloroplasts and the electrons will be boosted to higher energy. In this experiment NADPH is replaced by DPIP. The source of electrons that will reduce the DPIP is light.
Question 1: How does solar energy compare with fossil fuel energy in satisfying basic energy needs? What are the three fundamental problems in harnessing solar energy? Solar energy basically does the same as fossil fuel in providing for and satisfying basic energy needs. Example, flat plate collectors are used in warm climates to collect the suns heat and store it to be used to warm up water, solar energy can also be used and converted to provide electricity. Solar energy is more cost efficient and cleaner than the use of fossil fuels.
Through a process called photosynthesis, energy obtained from light is converted into chemical energy to be used by the plant as a source of sustenance. Along with carbon dioxide and water, plants use the sun energy to make sugar. There are two types of photosynthesis, oxygenic photosynthesis and anoxygenic photosynthesis. In order to understand photosynthesis you have to understand the site where it occurs. Chloroplast is where the process occurs.
An example of energy would be that plants only grow because the use the sun, which is light and then the plants use photosynthesis which is used by heat. The plants can then grow and store energy in the form of chemical energy. This also uses carbohydrates. The Krebs cycle is basically when energy is released from the carbon molecules during the Krebs cycle. This helps to reform ATP and then NADH is formed, this is originally a glucose molecule.
