Light Dependent Reactions The light dependent reaction of photosynthesis involves the transfer of sunlight energy into two things: The production of ATP Reduction of coenzyme NADP to NADPH NADP – Nicotinamide adenine dinucleotide phosphate NADPH – Reduced NADP The energy from sunlight is used to excite an electron‚ within a primary pigment‚ to a higher energy level. The excited electron is then donated to an electron acceptor leaving the chlorophyll molecule oxidised and reducing the acceptor

Identifying Dependent and Independent Variables Instructions: For each of the following research designs‚ identify the dependent and independent variables. 1. To investigate the effects of exercise on mathematical problem-solving ability‚ a researcher assigned subjects to one of two groups. One group did 50 jumping jacks and the other group did 200. After exercising‚ both groups did a set of math problems. 2. A researcher hypothesized that talking to plants enhances their growth. To test her hypothesis

Controlled Assessment ISA (PU 2.5) Light Dependent Resistors (Section 1) 1. Write down your hypothesis. Explain why you made this hypothesis. Hypothesis: When it is day there is more light hitting the LDR and so its resistance decreases and the light turns off. When it is night there is less light so the LDR has higher resistance and the light turns on. Explanation: When light shines on a Light Dependent Resistor‚ electrons are released and the current can get larger. So as the light intensity increases

Argumentative Essay In the present situation‚ people use technology to do almost everything for them. They use technology for trivial works like performing household chores to complex actions like executing complicated computer programs. According to my opinion‚ people have become extremely dependent on technology. Nowadays‚ people have laptops‚ eBooks‚ etc. and in some advanced countries like Japan‚ human teachers are being replaced with robot ones. Furthermore‚ we get the latest news from the

intelligence is through the use of too much technology. Technology today has become a part of our everyday lives and it has almost become impossible to live without it. There has been a plethora of research that leads us to believe technology has been the cause of more deficit disorders‚ addictive behavior‚ and sleep disorders than many other causes. This can be a problem when so many classrooms are moving towards the use of different technology within their classrooms. Technology can be a great resource to

Technology and advancement is great right? Sure‚ for some people. Technology and advancement can have its benefits‚ but it can also have its negative impacts as well. In fact‚ a perfect time period to see this negative impact in technological advancement is the second half of the nineteenth-century in America. American technology and industrialization changed the life of many social groups. Some positively‚ but most negatively. The urban population felt the worst impact during this period. The New

Photosynthesis Essay During the Light Dependent Reactions‚ activity occurs within the thylakoids of the chloroplast. NADP+ accepts two high energy electrons and an H+ ion and then converts into NADPH. This process ultimately traps some of the sunlight in chemical form. Then‚ NADPH is able to carry the energy it absorbs to the rest of the cell. The reaction produces O2 gas and converts ADP to ATP and NADP+ to NADPH. First‚ pigments in Photosystem II absorb light‚ which is then absorbed by electrons
