The light reactions of photosynthesis contain two photosystems‚ two electron transport chains‚ and ATP synthase. These parts are embedded in the thylakoid membranes of a chloroplast. The photosystems contain a collection of chlorophyll molecules. Chlorophyll‚ which is the green pigment of leaves‚ absorbs light energy that excites electrons to a higher energy level. Energized electrons from photosystem I are passed down an electron transport chain and added to NADP+ to form NADPH. Electrons from photosystem

Consumer classification and consumption patterns Ankit Verma Aditya Srivastava Rohit Sharma Motilal Nehru National Institute of Technology‚ Allahabad Abstract How the consumers consume and for what purposes‚ drives the producers as to how they extract resources and create products. The consumers are classified on the basis of consumption patterns which are ascertained by observing their actual behaviour in a market in various purchase situations. These patterns are explained by multiple

Biology lab: measuring the effect of light intensity on plant growth Aim: Investigate the effect of light intensity on plant growth Hypothesis: Light intensity will have an effect on plant growth. With an increase in light intensity there will be plant growth at a faster rate in comparison to when the light intensity is low where plant growth is limited and will take place slowly. When there’s too much light intensity‚ the light intensity will no longer become a limiting factor. A limiting

Trends in Consumption Patterns The business world is very susceptible to the subtleties of consumer choices. The ability to anticipate the trends in consumer consumption patterns is vital to any company desiring to be a leader or major factor in their industry. Millions of dollars are spent each year in research and analysis to determine or to create trends in‚ not only who the company’s customers may be‚ now and in the near future‚ but also‚ what will those customers want to buy‚ and why.

respiration and photosynthesis. Photosynthesis is performed by plant organisms and some bacteria‚ and cellular respiration is performed by all living organisms. These two processes are reliant on each other. Photosynthesis creates oxygen‚ which is used in cellular respiration. Cellular respiration in turn creates carbon dioxide‚ which is an important “ingredient” in the process of photosynthesis. Let’s take a closer look at what makes these processes so important to all living things. Photosynthesis is the

Photosynthesis notes -sunlight brings energy to Earth -the energy in sunlight is packaged in photons -the photosystems in the thylakoid membrane capture photons -pigments in the photosystems have an antenna complex that actually grabs the photons -chlorophyll b captures the photons and transfers the energy to chlorophyll a (the reaction center) -when the reaction center receives the energy it donates an electron -the donated electron will move down the electron transport system (ETS) -ETS

Photosynthesis depends on an interaction between two sets of reactions: the light reactions and the Calvin cycle. Chlorophyll and the other molecules responsible for the light reactions are built into the thylakoid membranes. The enzymes that catalyze the Calvin cycle are located in the stroma. Beginning with the absorption of light by chlorophyll‚ the light reactions convert light energy into chemical energy in the form of ATP and NADPH. The ATP provides the energy‚ and the NADPH supplies the electrons

Since the start of the decade‚ there has been a 50% increase in the number of CCS projects in operation or under construction. This increase is represented by the thirteen large-scale global CCS projects that are currently in operation‚ and the additional nine that are under construction. The total carbon dioxide capture capacity of these twenty-two projects is estimated to be around 40 million tonnes per year. Additionally‚ there are fourteen large-scale CCS projects at the most advanced stage

Effects of Particle Size‚ Temperature‚ Concentration‚ and a Catalyst on Reaction Rate Introduction: Chemical reactions can be affected by a number of different factors. Particle size‚ temperature‚ concentration of a solution‚ and catalysts play a big role in the rate of reaction‚ they determine how fast a reaction will occur. According to the collision theory‚ the rate of reaction depends on the frequency of effective collisions between particles. Every reaction is different in that they all
