effect of substrate concentration on the rate of enzyme activity of Catalase Aim To investigate the effect of substrate concentration (manipulated by increasing concentration of hydrogen peroxide) on the rate of enzyme activity of catalase‚ produced by liver cells‚ on the decomposition of hydrogen peroxide. Introduction Enzymes are biological catalysts that increase the rates of reactions. In an enzyme-catalyzed reaction‚ the substrate binds to the active site and forms enzyme-substrate complex

and trees cover about thirty percent of the planet’s surface‚ as stated in NASA’s Earth Observatory division. They use a process called photosynthesis‚ which allows plants to take energy from the Sun and later using it as food‚ as well as producing oxygen through the process of respiration. So how does it happen? The process of photosynthesis occurs as follows. First‚ the plant uses the sunlight and the green color in their leaves to make sugar from carbon dioxide‚ or CO2‚ which is in the air. At

system to discuss the relapse rate of criminals. Recidivism is when a proportion of a specific group of offenders that have been released from prison recommit crimes within a certain period of time. Recidivism is basically to relapse. How Toni Fabelo Proposes to Measure Recidivism In order to measure recidivism‚ Fabelo stresses to have a full understanding of recidivism‚ understand how it is measured‚ and determine the implications of adopting recidivism rates as measures of performance (Maxfield‚

Biology Lab Report Investigating Alcoholic Fermentation and the Affects of Yeast on Dough Aim: The aim was simply to investigate whether or not yeast had any affect on causing dough to rise when baked and to experiment with alcoholic fermentation eg. to see if it gave off carbon dioxide. Introduction: Following a few weeks of fermentation theory‚ groups of three to four were assigned and told to conduct a series of experiments involving the affects of fermentation. My group consisted of

CELLULAR RESPIRATION -is the set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP)‚ and then release waste products. The reactions involved in respiration are catabolic reactions‚ which break large molecules into smaller ones‚ releasing energy in the process as weak so-called "high-energy" bonds are replaced by stronger bonds in the products. Respiration is one of the key ways

Cyanobacteria’s big advantage over other early life forms was their ability to perform photosynthesis. They contain a blue photo reactive pigment that can absorb the energy from the sunlight and use it to produce nutrients for the cell. During this process‚ water molecules are broken down into oxygen and hydrogen atoms which are then released in the air. In the very early days of life‚ Earth was populated only by anaerobic bacteria that didn’t need oxygen to survive. When cyanobacteria first made
