Abstract The following experiment details the effect of different concentrations of catalase on the production of oxygen and water through the breakdown of Hydrogen Peroxide. In this experiment paper disc where coated in varying concentrations of catalase‚ 0‚ 25‚ 50 75 and 100%. The time taken for the disc to float between two markers on the side of a glass was then recorded. This experiment demonstrates that the higher the concentration of enzyme used the greater the production of oxygen on the

BIOLOGY Coursework Photosynthesis Made By: Mike Alexander= Definition: Photosynthesis is a process by which plants make their own organic‚ complex food (glucose) from organic‚ simple‚ raw materials using sunlight energy (which is converted to chemical energy) and enzymes in the chloroplasts (mainly mesophyll cells called palisade cells). How It Works: Carbon Dioxide + Water  Glucose + Oxygen 6CO2

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

Conclusion I predicted that if the decolorization of DPIP is caused by photosynthesis and not cell respiration and spinach extract containing chloroplasts and mitochondria is incubated with DPIP‚ then the rate of DPIP decolorization should be higher if in bright light verses dark light because DPIP is reduced by photosynthesis and not by the mitochondria or any other cellular function. If DPIP was only decolorized by chloroplasts‚ then the percent transmittance of chloroplast suspensions would be

Visible light (commonly referred to simply as light) is electromagnetic radiation that is visible to the human eye‚ and is responsible for the sense of sight. Visible light is usually defined as having a wavelength in the range of 400 nanometres (nm)‚ or 400×10−9 m‚ to 700 nanometres – between the infrared‚ with longer wavelengths and the ultraviolet‚ with shorter wavelengths. These numbers do not represent the absolute limits of human vision‚ but the approximate range within which most people can

Photosynthesis Lab Report Purpose: To research the effect of different wavelengths (colors) of light on plant growth during photosynthesis. Background Information: Photosynthesis is the process by which sunlight is captured by chloroplasts within plant cells and turned into energy. This energy is used to help the plant grow roots‚ leaves‚ flowers and fruit. Energy is required by living things

Effect of light on Silver Halide Salts Aim: To investigate the effect of sunlight and UV light on silver salts and to identify an application of this reaction. Hypothesis: The compounds exposed to sunlight (which already contains UV light) will decompose. The compounds which are not exposed to light (put in a dark place) will not decompose. Theory: Equipment: * 4 x petri dishes * 1 x glass stirring rod * 0.1 mol/L silver nitrate in a dropper bottle * 0.1 mol/L Sodium chloride

think of weight training intensity does someone yelling phrases like those come to mind? Well if it does then you are partly correct‚ but what does weight training intensity actually mean? Following the thread of the last two articles ive done dealing with creating your own workout plan and defining training volume‚ today we’ll look at what training intensity is and how to apply it. WHAT IS INTENSITY IN WEIGHT TRAINING From my research ive found that training intensity meaning is actually
