place in chloroplasts‚ which is a plastid that contains chlorophyll and involves two interlinked reactions‚ which are light dependent reactions and light independent reactions. Throughout our lab experiment‚ we focused on the affect access of light has on carbon dioxide during photosynthesis. Carbon dioxide levels decrease as oxygen levels increase and glucose is produced when light dependent reactions occur. Light energy is absorbed by photo pigments and is used to raise a electron to a higher energy

order for the biochemical reactions to occur because they act as a catalyst to convert energy from sunlight into chemical potential energy. Two consecutive steps allow the photosynthesis process to take place. These steps are light-independent reactions‚ and light dependent reactions. The occurrences of Light-independent reactions happen in the STROMA of the chloroplasts. The substances consumed during this reaction are ATP and NADPH. The occurrences of light-dependent reactions happen within the THYLAKOIDS

Enzymes are responsible for multiple reactions that take place naturally in the living organisms. The purpose of the enzymes lab was to investigate how the enzymes play a role in a reaction‚ affecting the rate of reaction (ROR). Interestingly‚ we tested how the enzymes affect the reaction rate at multiple temperatures (0‚ 23‚ 37‚ 50‚ 70‚ and 95 C). It was predicted that an increase in temperature will elevate the thermal activity of substrate which increases the chances the substrate molecules will

multiple variables were tested in specific concentrations; that test the reaction rates of the enzyme catalase over a fixed period of time. The major conclusion was that catalase reacts faster in warm temperatures that are neither freezing nor boiling‚ catalase performs well in lower concentrations than the substrate‚ and catalase prefers neutral pH levels around 7. Introduction Enzymes are proteins that catalyze metabolic reactions vital for the survival and functioning of cells [1]. Without enzymes

Taking an unknown compound and identifying it by purifying it from its impurities through the use of hot gravity filtration. Then to determine the unknown you were to take the melting point. An unknown compound was recrystallized from hot water to produce 0.99 grams (67% recovery)

NaHCO3 and NaCl and calculate a balanced equation for this reaction. Safety: • Wear safety goggles at all time • Handle all chemicals with care • Use equipment like tongs when handling warm/hot objects • If chemicals are spilt on self‚ wash off immediately • Stand at all times Hypothesis: The NaHCO3 will react successfully with the HCl and will form NaCl‚ H2O and CO2. Then be able to work out a balanced equation for the reaction and work out the moles of NaHCO3 and NaCl. Materials:

Abstract By working with physical isopods‚ ordinarily known as pill bugs‚ sow bugs or roly- polies‚ we tried whether these sowbugs favored a dark spot to a light place. Included in the lab are a few outlines and tables sketching out our aftereffects of the test. We measured recurrence

October 18‚ 2011 Biology Lab report Proteins are very important throughout the body. They have a lot of functions in cells. Antibodies are proteins that help cells rebuild the cells when they are destroyed. Transport proteins move substances from one place to another. Regulatory proteins control cellular metabolism in a way that cells throughout the body can have the right amount of glucose in the blood. A common protein is an enzyme; in cells they speed up chemical reactions. For an example‚ “amylase

Physics Lab Report Format General Remarks: Writing a lab report is the only way your TA will know what you have done during the lab and how well you have understood the process and the results. Part of your lab experience should be learning how to organize and present your work in a scientific way. There is no framework that can be used as a “one size fits all”‚ therefore this sample lab report should only be used as an example. Any lab report should have the following features:

Engineering Laboratory (Lab) Report Department of Engineering Faculty of Engineering and Science‚ University Tunku Abdul Rahman (UTAR) 1. Introduction Laboratory (Lab) reports are the most frequent document written by engineering student. These reports can contribute a significant amount of marks and yet little time or attention is devoted in understanding on how to write them well. The aim of this document is to provide a general guideline on writing a lab report. A lab report should not be
