The effects of different wavelengths of 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

The effect on rate of an enzyme catalysed reaction by different objectives which include effect of substrate‚ temperature‚ ph and effect of a competitive inhibitor phosphate ions. This is determined by the reaction of hydrolysis by p-nitrophenylphosphate (PNP) as a substrate by the enzyme phosphatase. Abstract The hydrolysis of p-nitrophenyl phosphate has been studied in human red blood cells. To see if hydrolysis was related to the functioning of the sodium pump. Acid phosphatase catalysis’s

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 fermentation has been used

Tyler Cowan Professor Foltz Biology 181 April 8th 2015 Lab Report: Respiration Abstract: The objective of this lab was to figure out which has a higher cell respiration rate between crayfish and elodea. In order to figure this out we first set up three beakers to represent our control‚ elodea and crayfish and filled them with 75mL of culture solution which were dechlorinated making the solution acidic. We then had to place both the elodea and the crayfish in separate beakers filled with 25mL of

normally recognised as a drug to most. Caffeine has an effect on your heart rate‚ (this is how fact your hear beats) Caffeine is able to change the way your body and mind works Chocolate is known to have traces of caffeine in it also The aim What is the point this experiment;- My aim in this experiment is to see what effects caffeine is prone to on the heart rate‚ Also to compare someone’s heart rate who has consumed caffeine to someone’s who hasn’t. This should give us a developed

Abstract The effect of nature of substrates on the rate of cellular respiration in yeast was determined by using the Smith fermentation tube method. Mixtures of 15ml distilled H2O‚ 10% yeast suspension and 15ml of the following solutions (all at 10% concentration):1- starch‚ 2 – lactose‚ 3 – sucrose‚ 4 – glucose‚ 5 – fructose‚ 6 – distilled water ‚ were poured in six smith fermentation tubes. Cotton balls were plugged in the openings of the tubes and the tubes were kept upright and observed for

Pulse rate is the number of times in a minute an artery pulsates or the rhythmic expansion and contraction‚ which indicates that a heartbeat has occurred. There are many factors which affect the pulse rate which includes: gender‚ age‚ body temperature‚ pain‚ emotion‚ exercise‚ blood pressure‚ consumption of stimulants‚ dehydration‚ body mass index (weight)‚ fitness level‚ lifestyle and many more. In my investigation‚ I would be examining the affect of gender in the change in the pulse rates‚ while

Factors that affect exchange rates. Like any price‚ the exchange rate deviates from the cost basis - the purchasing power of currencies – under the influence of supply and demand of currency. The ratio of the supply and demand depends on several factors. It reflects connections with other economic categories - cost‚ price‚ money‚ interest‚ balance of payments‚ etc. There is a complex of interweaving and nomination of decisive factors. Among them are the following. • 1.The rate of inflation. The
