Period : 4 Grade : 11 Enzyme Lab Report Question How heats effect the length of reaction time of an enzyme? Hypothesis I think the heat will make the length of reaction time of an enzyme become slowly. Heat is one of a way to denature the substrate. It means the heat will break down the structure of substrate in order the reaction of enzymes that we activated into it become slowly. Method for Collecting Data First I will record the length of reaction time with stopwatch when I pour

The Biological Importance of Water Water is perhaps the most important molecule for the survival and life of organisms. On the surface of the planet there is obviously much more area of water than land‚ which shows its significance. The fact that water makes up 60-95% of all living organisms shows the incredible biological importance of water. Water has many uses and roles‚ one of them it being used as a support unit in plants. The uptake of water by plant cells creates a pressure against the rigid

Label five test tubes 1-5. Place 4 mL of 1 % starch in each of the first four test tubes. Place 4 mL of amylase solution in the fifth tube. Place all of the tubes in the 37°C water bath for 5 minutes. Obtain 5 clean droppers and label them 1-5. (To avoid contamination of these solutions

Enzymes What Are Enzymes? Substances that speed up chemical reactions are called catalysts. Organic catalysts are called enzymes. Enzymes are specific for one particular reaction or group of related reactions. Many reactions cannot occur without the correct enzyme present. They are often named by adding "ase" to the name of the substrate. Example: Dehydrogenases are enzymes that remove hydrogen. Induced-fit Theory The shape of the enzyme must match the shape of the substrate

Week 7 Essay Define "biological productivity.” When a scientist says productivity is a rate‚ what does she or he mean? List several factors that influence productivity in various ocean environments (the surf zone‚ mid-ocean and the deep abyss). According to encyclopedia2 the definition of biological productivity is “The productivity of organisms and ecosystems‚ as defined by primary‚ secondary‚ and community productivities. So when a scientist says productivity is a rate‚ he or she is referring

1) Biological Approach The Biological approach studies the relationship between behavior and the brain and nervous system. Theorically all behavior can be related to changes in brain activity. Because brain is the processing centre that controls all complex behavior. One of the main assumptions of the biological approach is that all behavior is associated with changes in brain function. Therefore the psychopathology will occur due to changes in either the structure if related to changes in the

temperature‚ pH‚ enzyme concentration‚ and substrate concentration on the reaction rate of an enzyme-catalyzed reaction. Another purpose of the lab was to explain how environmental factors affect the rate of enzyme-catalyzed reactions. Hypothesis: I believe that if there is an increase in enzyme concentration‚ an increase in temperature‚ or an increase in pH‚ then the intensity of the reaction will increase‚ which will cause greater alterations in the product of the reaction. I think this

Investigating the effects of changing temperature on the activity of enzymes Background information: Renin is an enzyme that catalyses the coagulation of milk. It is found in the stomach of many animals and is used in making cheeses and junkets. It is found in the gastric juices or gastric mucosa of many mammals‚ including humans. In the human stomach‚ particularly those of infants‚ rennin works to curdle milk so that pepsin‚ another stomach enzyme‚ can further breakdown the proteins into absorbable amino
