Cells of all organisms are capable in acquiring the energy necessary to fuel chemical reactions for growth‚ repair‚ survival‚ and reproduction. Photosynthesis & cellular respiration are the main pathways of energy flow in living things. Photosynthesis is a process by which plants and some other organisms convert‚ light energy from the sun‚ CO2 from the air & H2O from the earth‚ into chemical energy stored in molecules like glucose. Cellular respiration is a process in which O2 is delivered to cells

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

spectrophotometer is an instrument that measures the quantitative amounts of light of different wavelengths absorbed and transmitted by a pigment solution (Mitchell‚ Reece). The spectrophotometer includes a light bulb‚ a reflector‚ and a detector. When a sample is in place and the chamber lid is closed‚ light from the light bulb passes through it. The detector measures the amount of light transmitted. The white light from the bulb is separated into different wavelengths by reflecting the beam

into one topic with the question of is it needed when disciplining children? When analyzing this topic it is found to have key issues and controversies surrounding whether corporal punishment have negative or positive effects on children when they are exposed to it‚ there are also multiple perspectives to be looked at about using corporal punishment when it comes to disciplining children. The analysis and summary of corporal punishment and whether it is needed to discipline children include additional

because blue light has a higher absorbance by plant photosynthetic pigments and has a higher energy wavelength than red light‚ we predicted that juniper needles placed in blue light would photosynthesize faster than juniper needles placed in red light. We measured the rate of change in CO2 concentration due to juniper needles. For each sample‚ we placed the needles into a chamber connected to the CO2 monitor and measured the rate of change of CO2 concentration for 10 minutes under red light and then

Jolly Nguyen 11C Conditions needed for effective enzyme action Aim: To investigate the activity of enzymes and how might the activity be effected in different conditions. Hypothesis: Temperature rises and change of substrate concentration may cause denaturation of the protein of enzymes. So as the temperature rises the amount of active enzyme progressively decreases‚ and the rate is slowed. Exposure to heat causes atoms to vibrate violently and this disrupts bonds within globular proteins
