INTRODUCTION Overall‚ light energy drives a flow of electrons along a system of carriers from H2O to NADP+. The carriers are bound to the membrane between reaction centres. Though their precise arrangement is not known‚ the carriers seem to be organized so that the electron flow cause H+ to move from the stroma to the space within the thylakoids. The resulting difference in H+ concentration across the membrane represents a store of energy that is though to drive he formation of ATP. According to

that physical activity and healthy eating is important for a long and healthy life. If you eat healthy‚ combined with High Intensity Interval Training‚ you are going to reach top physical condition much more efficient than doing another sport. Amy Schlinger introduces in her article‚ “HIIT Workout: What It Is And Why It Works”‚ a modern training technique called High Intensity Interval Training. The article says the main idea is to try as hard as possible in an intense quick exercise which is followed

Natural Selection Intensity among four Hindu Varna populations of Lucknow Disttict‚ Uttar Pradesh Vibha Devi Bajpai and Dr. Udai Pratap Singh Department of Anthropology‚ University of Lucknow‚ 226007‚ U.P. India Abstract The selection intensity indices were calculated based one demographic information pertaining to fertility and mortality among the four Varnas of Lucknow population.The highest value of Crow’s index is observed in Kshartiya (0.494934) where as lowest in Brahmins (0.365809).

use a process called photosynthesis to covert energy from the sun into energy they can use for their activities. The plant’s chloroplasts‚ along with water‚ carbon dioxide‚ and light are the essential elements required for photosynthesis to take place. The “photo” part of photosynthesis is in reference to the fact that the process requires light. The simplest form of the photosynthesis equation is: H2O + CO2 ----light----> (CH2O)N + O2 As shown in the equation‚ photosynthesis produces carbohydrates

The rate of photosynthesis in each of the beakers will depend what is wrapped around the beakers such as red and blue cellophane‚ as well as the control of the experiment the beaker without cellophane. The cellophane will directly impact the light getting absorbed as well as the amount of CO2 in the beakers. Which overall as result will determine the final color of the water mixed with bromothymol blue. What was being measured was the color of the water after CO2 has been blown in the beakers. The

Photosynthesis Background Do you know what is the most important process that sustains life? Photosynthesis‚ that is the correct answer! Photosynthesis‚ is known as the process to produce plant food. But‚ how does is the life exist on the planet we call our home‚ Earth? Photosynthesis is a process that we know that allows water‚ carbon dioxide‚ and some mineral salts along with the light from the sun to make glucose (sugar). During the process‚ the root sytem of the plant takes in elements

AMDG THE RATE OF PHOTOSYNTHESIS The Factor of Carbon Dioxide I. Introduction In this lab‚ the rate of photosynthesis will be measured by manipulating a variable that is needed for the process of photosynthesis. Photosynthesis is the process by which plants use light energy‚ carbon dioxide‚ and water to produce oxygen and glucose. This release of products provides the necessary nutrients for all forms of life. In water‚ leaves‚ usually float in water due to the gases such as carbon dioxide and

Osmosis is the diffusion of water molecules across a semi-permeable membrane. Diffusion is the movement of molecules from an area of high concentration‚ to an area of low concentration. So‚ Osmosis is the movement of water molecules from an area where there are lots of water molecules to an area where there are few water molecules. Our aim is to find the concentration of dissolved substances in the cells of a potato using Osmosis. I predict that the potato in the higher concentration of salt

Investigating Vitamin C Background Vitamin C is found in green vegetables‚ fruits‚ and potatoes. It is essential for a healthy diet. The chemical name for vitamin C is ascorbic acid. Ascorbic acid is a good reducing agent and therefore it is easily oxidised. Methods for the detection of vitamin C involve titrating it against a solution of an oxidising agent. Where to start There are several oxidising agents that can be used and a commonly used one is 2‚6-dichlorophenol-indophenol or DCPIP
