product. This is different from respiration because respiration transforms chemical energy into energy usable by cells; in this case chemical energy is the source. Photosynthesis occurs in the chloroplasts‚ using the chlorophyll inside of the chloroplasts‚ while respiration occurs in the mitochondria. Photosynthesis produces oxygen as a by-product‚ while aerobic respiration requires oxygen to even work. Photosynthesis produces NADPH2 in its workings‚ while aerobic respiration produces NADH+.

Biology Revision Notes Biochemical Tests: Proteins - add biurettes reagent to the sample. If protein is present‚ clear colour change from blue to purple. Reducing Sugars – add Benedict’s reagent to the sample. Heat in Bunsen or water bath. If reducing sugars are present‚ clear colour changes from blue -> orange red precipitate. Lipids – dissolve sample in ethanol. Slowly pour the solution into the water slowly. If lipids are present a white emulation forms on the surface. Starch – add iodine

Understanding the function of cellular respiration and fermentation is easy to learn. However it is more difficult to learn the process of glucose being converted into energy. Cellular respiration has four stages‚ of which a phase can consist of eight or ten steps. In the Krebs Cycle alone‚ there are ten steps‚ where the input of Acetyl CoA is eventually reconverted back into oxaloacetate. Fermentation is also no different. It can be difficult for students to understand what the role of NADH

Ph Lab Report Bryon Kim 123013 B(2) Biology Background information/Research PH paper (litmus paper) determines how acidic or how basic a substance is. The paper changes color accordingly to color code on the pH scale. The pH scale starts from 0 to 14. The lower the number the more acidic it is. Zero is the most acidic‚ and 14 is the most basic while 7 is the neutral number for example water. Examples of an acid is lemon juice or multi purpose cleaner. Examples of a basic substance is shampoo or liquid soap

January 31‚ 2014 Mr. Robinson IB Biology I 2ND Period The Effects of Light on Plant Growth Introduction: Photosynthesis is the process in which plants use light energy‚ water‚ and carbon dioxide to produce food. Plants use the food they make for the growth and for the carrying out other life processes. Sunlight is the natural energy source for photosynthesis. White light form the sun is a mixture of all the colors of the light spectrum: red‚ orange‚ yellow‚ green‚ blue‚ and violet. Light

and Aerobic metabolism using pea seedlings and yeast organisms [1]. Aerobically‚ sugars such as glucose are transformed into pyruvate [2] and then into Acetyl CoA. This is then put through the citric acid cycle which is a series of reactions that oxidize acetyl units into carbon dioxide [2]. Following

Effect of Exercise on Heart Rate. Aim: The aim of this experiment is to find out how different intensities of exercise effect the heart rate I will measure it in beats per minute using a polar heart rate monitor. Hypothesis: I predict that as I increase the intensity of the exercise I do‚ that my heart rate will increase. This is because as I exercise more intensely I will need more blood to my muscles to supply oxygen and take away carbon dioxide; therefore my heart is going to have to beat

To investigate how does the concentration of Hydrochloric acid affect the rate of reaction? Outline I aim to discover how different concentrations of Hydrochloric acid influence the rates of reaction. In order to carry out this investigation I have decided to use marble chips‚ which I will vary the sizes as powder‚ small chips and large chips. I will also be changing the concentration‚ the different concentrations are as follows 0.2m‚ 0.5m‚ 1m‚ 1.5‚ 2m. I have chosen these concentrations as they
