Carotene‚ and Xanthophyll. Introduction Chlorophyll is the molecule that absorbs sunlight and uses its energy to synthesize carbohydrates from CO2 and water. This process is known as photosynthesis and is the basis for sustaining the life processes of all plants. Since animals and humans obtain their food supply by eating plants‚ photosynthesis can be said to be the source of our life also. As the chlorophyll in leaves decays in the autumn‚ the green color fades and is replaced by the oranges

light on the rate of photosynthesis Introduction This experiment was performed to investigate the effects of different wavelengths of light on the rate of photosynthesis. If a multiple colored film petri dishes are place under a 50 watt lamp‚ then the rate of photosynthesis will be greater for those with red‚ blue and clear film‚ than those with green and black film. We believed the petri dishes with the red‚ blue and clear film would produce the best results of photosynthesis as compared to the

ANAEROBIC AND AEROBIC METABOLISM Lab 5 BCEM 341 – Winter 2014 Nebojsa Kuljic 10066717 Partner: Kendra Skalyn B02 Introduction Cells of all organisms can obtain energy through the combustion of sugars‚ either in the presence of oxygen (Aerobically) or without oxygen (Anaerobically). The purpose of this experiment was to perform a quantitative investigation of the differences between Anaerobic and Aerobic metabolism using pea seedlings and yeast organisms [1].

Examining the Effects of Mass and Type Of Sugar on Yeast Fermentation Lab Purpose: To measure and analyze the effects of various types and masses of sugar in an ethanol fermentation reaction with yeast. Introduction: Ethanol fermentation is a system in which hydrogen ions from NADH + H + are broken down in order to release the trapped energy and regenerate NAD+. In the absence of a mitochondria or oxygen ethanol is formed‚ which is typically found in bacteria and some yeast. Yeast
