Sang Kim Enzyme Catalyst Purpose/Problem: There are four parts to the Enzyme Catalyst lab - Activity A‚ B‚ C‚ and D. In activity A‚ the characteristics of enzyme actions will be observed. The main purposes are to determine the rate of an enzyme catalyzed reaction‚ to study the characteristics of an enzyme mediated reaction‚ and to observe the effect of heat on enzyme activity. The purpose of activity B is to use the Titration Protocol to determine the initial amount of H 2O2 present

order to examine its heartbeat by using the microscope. Aim In this Lab we will study the effect of different concentrations of adrenalin on the heart rate daphnia‚ the water flea. It is expected to recognize a threshold of the daphnia in its reaction the three different adrenalin concentrations‚ in terms of heart rate. Background The endocrine system works with the nervous system to regulate and coordinate body functions. While the nervous system works quickly and sends messages directly to

Biology 1010 is a course that introduces students to the basic biological phenomena in all living organisms. It focuses on the different molecular levels of organization‚ heredity in evolution‚ genetics and reproduction. Through this course‚ I was able to master three essential concepts such as Mendel’s Law of Segregation‚ enzymes‚ and photosynthesis. Gregor Mendel was an Augustinian monk that argued that parental traits are passed on to their offspring discrete “heritable factors”. Heritable factors

Nervous System and Sensory Organs • dorsal roots and ventral roots - connect Spinal nerves to the spinal cord • medulla -responsible for many involuntary functions such as heartbeat and breathing‚ primary communication pathway between the spinal cord and the rest of the brain‚ • cerebellum - receives input from multiple sensory receptor types and uses this information in coordination of complex body movements • pons- communication between lower and higher brain regions • midbrain- processes

contain chemicals‚ as well as cancer-causing substances. Tar is brown and sticky posing stains on fingernails‚ teeth‚ and lung tissue. Carbon monoxide This gas is deadly if consumed in large amount because it replaces oxygen in the red blood cell. Red blood cell contains haemoglobin that transports oxygen molecules from the lungs to other parts of the body. On the other hand‚ haemoglobin has higher affinity to carbon monoxide as compared to oxygen. This shows that less oxygen reaches the brain‚ muscles

Tomato Sweetness Jessica Pursell American InterContinental University 01/18/2015 Biology IP2 Introduction You and your neighbor have small kitchen gardens where you both grow tomatoes. His blotchy green and red tomatoes taste much sweeter than your perfectly uniform red ones. Could the sweetness of the tomatoes be effected by the green chloroplasts in the fruit? Hypothesis I personally think that the green chloroplasts do play a part in the sweetness of the tomatoes because it doesn’t

Cell Respiration Respiration is the process by which organisms burn food to produce energy. The starting material of cellular respiration is the sugar glucose‚ which has energy stored in its chemical bonds. You can think of glucose as a kind of cellular piece of coal: chock-full of energy‚ but useless when you want to power a stereo. Just as burning coal produces heat and energy in the form of electricity‚ the chemical processes of respiration convert the energy in glucose into usable form. Adenosine
