from sunlight. Plants‚ algae‚ and some bacteria use the energy captured during photosynthesis for their metabolic reactions. During photosynthesis in plants‚ chlorophyll and enzymes in leaves convert certain wavelengths of light into chemical energy. A simple equation can be used to represent photosynthesis. Enzymes and Chlorophyll light energy CO2 H2O carbohydrate O2 In this investigation you will examine the relationship between the amount of light energy available and the rate of use

This part of the experiment yielded an exothermic reaction. The purpose was to calculate the specific heat capacity and molar mass of the zinc metal. The specific heat capacity was found to be 0.197 J/g °C with a percent error of -49.5%. The molar mass was found to be 127 g/mol with a percent error of 94.2%. Possible sources of error inherent to this segment of the experiment were the fact that when the temperature of the solution was being measured

What are amylases? Amylases are enzymes that break down starch or glycogen. Amylases are produced by a variety of living organisms‚ ranging from bacteria to plants and humans. Bacteria and fungi secrete amylases to the outside of their cells to carry out extracellular digestion. When they have broken down the insoluble starch‚ the soluble end products such as (glucose or maltose) are absorbed into their cells. Amylases are classified based on how they break down starch molecules i. α-amylase

Effect of temperature of the reaction: The effect of the temperature of the reaction on the activity of the purified enzyme was carried out by make the enzymatic reaction for 10 minutes at different temperature 25‚30‚35‚40‚45‚50‚60 and 70°C using an enzyme protein 0.1mg/reaction mixture and substrate concentration of 15 mg/reaction mixture‚ using a control of previously heated enzyme solution in the reaction. The data recorded in (table 27) and (figure 29) illustrate the effect of temperature of the

on heart rate OBJECTIVE To determine the effect of caffeine on heart rate of daphnia INTRODUCTION Caffeine‚ medically known as trimethylzanthine. Its chemical formula is C8H10N4O2. When in pure form‚ caffeine is a white crystalline powder that taste very bitter. 1The most common way of acquiring pure caffeine is the process of decaffeinating coffee and tea. Caffeine is found in varying quantities in the seeds‚ leaves‚ and fruit of some plants‚ where it acts as a natural pesticide

Experiment 4 – Effect of Temperature on Enzyme Activity Aim To study the effects of temperature on the activity of amylase enzyme on starch solution. Introduction Enzymes are widely known as biological catalyst. Almost all cellular reactions are controlled and guarded by enzymes. Virtually every metabolic reaction which takes place within a living organisms are catalyzed by enzymes. Enzymes are complex three-dimensional globular proteins. Some of the enzymes are built up off proteins and

Abstract The aim of this experiment was to investigate the effect of temperature on the enzyme catalase. The original research question was exploring the effect temperature would have on a yeast catalase reacting with hydrogen peroxide (H2O2). To address the latter question a series of experiments were conducted. The various temperatures experimented with were as follows: 22 degrees Celsius (room temperature)‚ 0 degrees Celsius (freezing)‚ 100 degrees Celsius (boiling)‚ and 37 degrees Celsius.
