Digestion and Enzymes – APP. Hypothesis: The enzyme‚ Amylase which is used to break down carbohydrates will work the best when heated at 40°C. Also‚ as the temperature increases the reaction rate of amylase increases too. However‚ the reaction rate of amylase will start decreasing when the temperature reaches the enzyme’s optimal temperature. Many enzymes are specific for a certain substrate. For example‚ lipase is a specific enzyme for fat substrates and protease‚ a specific enzyme for

Click Introduction to Chemical Digestion. Introduction 1. Explain the function of chemical digestion. The function is to break down food‚ using enzymes and other digestive chemicals to reduce food into particle nutrients molecules that be absorbed and move it through the digestive tract.

Introduction/Background: This week’s lab is about digestion and the circulatory system. Students will be learning about the different types of digestion and circulatory systems for different types of animals. Students will learn not only about the mechanical and chemical components of digestion‚ but also the complete and incomplete digestions. The lab will also teach the open and closed‚ single and double‚ circulation patterns. Several different models of the systems will be shown in lab. Learning these different

Define the following terms: Digestion: Digestion is the breakdown of large insoluble food substances in small and soluble one by means of mechanical and chemical actions. Peristalsis: It is a series of alternate contraction and relaxation of the circular and longitudinal muscles‚ producing a wave-like motion to move food down the oesophagus‚ from the mouth to the stomach. Emulsification: It is the hydrolysis of a few large fat globules into many small and soluble fat molecules. Transpiration:

this project. I am grateful to Prof. Dharmendra Sharma‚ The HOD ‚ Department of chemistry for providing us the lab facilities and chemical required for carrying out this investigation. I also express my gratitude to our lab assistants Sri Niranjan Deka‚ Sri Pranjal Borah‚ Sri Pratim Saikia and Sri Ratul Borah for their willingness in providing us with necessary lab equipments and constant support without which its effort would have been worthless. I am grateful to my parents

the science lab. In science‚ we would participate in a lab. One of my favorite labs was the owl pellet dissection. Owl pellets are owl throw up. In owl pellets you can find the bones of animals the owl consumed. In this lab we were to take out the bones we found in the pellet and construct the animal we found inside. Most people‚ like me‚ had a sort of rodent‚ but some people found birds in their pellet. Another one of my favorite things we did in science was the Sharpie tie dye lab in fifth grade
