Chapter 6-Intro to Metabolism METABOLISM= all the chemical reactions in an organism CATABOLIC PATHWAY (CATABOLISM)• release of energy by the breakdown of complex molecules to simpler compounds EX: digestive enzymes break down food ANABOLIC PATHWAY (ANABOLISM) • consumes energy to build complicated molecules from simpler ones EX: linking amino acids to form proteins ORGANISMS TRANSFORM ENERGY ENERGY- capacity to do work KINETIC ENERGY- energy of moving objects POTENTIAL ENERGY- energy

Photosynthesis is a crucial energy conversion process that occurs in the chloroplasts of eukaryotic cells. The rate of photosynthetic activity holds importance in environmental‚ horticultural and agricultural situations. (Boardman‚ N.K. 1977). Pigments in the chloroplasts thylakoid membrane absorb the electromagnetic radiation from a light source and release an electron into the electron transport chain. DCPIP’s chemical ability to favourably accept electrons‚ and undergo a colour change from

Is photosynthesis important for life? Is photosynthesis important for green plant‚ animal‚ Earth and human? I believe that photosynthesis is major on make fresh air and make the plants own food. I believe that photosynthesis is important for life because the fresh air from the chlorophyll is doing photosynthesis. Plants also make food and oxygen. Then plants is doing photosynthesis‚ it must have sunlight to make their own food and oxygen. The equation about photosynthesis basically is CO2 +

Component seeks to separate‚ identify‚ quantify and analyze the active component found in Biogesic®‚ which may be useful for public awareness despite its wide acceptance and availability in the market. Furthermore‚ this study applies thin layer chromatography (TLC) technique since it is the simplest‚ cheapest yet most effective approach in terms to the study’s objectives. The TLC method implies Rf (Rate of flow) values where it is given by the distance from origin to center of subtance spot over the

PHOTOSYNTHESIS (How do the light dependent and light independent reactions provide food for a plant?) Why? How important are plants to life on Earth? Could life as we know it continue if there were no plants? Read on the find out why plants are truly the cornerstone of life. Model 1: An Overview of Photosynthesis and Chloroplast Structure 6CO2 + 6H2O C6H12O6 + 6O2 Site of the Calvin cycle‚ or light independent reactions 6 H 2O + 6 CO2 Contains chlorophyll. This is the site of the light dependent

Photosynthesis 1. Would you illuminate your house plants with a green light bulb? Why or why not? It would not be a wise choice to put a plant under a green light bulb. The reason for this is that due to the fact that the leaves are green they reflect green light. This shining green light onto the flowers will cause photosynthesis to stop. Since the light is being reflectd‚ the cells do not get any light. With out light they cannot carry out the everyday occurrence of photosyntesis. If 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
