Testing for reducing sugars‚ non-reducing sugars‚ starch‚ lipids and proteins in unknown substances: Our aim: was to find out which substances from our five samples have reducing sugars present to determine what they may be for example; they could be monosacchrides or disaccharides. This was carried out by using Benedict’s test. To find out which substances from our five samples were non-reducing sugars‚ since some disaccharides are reducing sugars and this would be carried out by using Benedict’s

Does the PH level of acids in our stomach affect the digestion proteins? Yes‚ if the acidity in my/a stomach is high in terms of the PH balance then the proteins in our stomach will be digested faster because acids are known to breakdown and eat away at many objects. The purpose of this project was to observe how the digestion of protein varies at different pH levels. This project in my eyes helps society by finding the best types of food (i.e. ones with higher/ lower acidity and pH balance)

1. tested and measured? The purpose of this experiment was to determine whether the dark or light coleus leaf had the presence of starch. We used a dark and light leaf to test the presence of starch and how much was produced. 2. Summarize the results and how the results were obtained. Be sure to note the reason for each treatment of the leaves. As appropriate‚ compare experimental samples to controls. Both leaves were boiled in water then placed in hot ethyl alcohol. After adding the iodine

purposes. An example of which is the coconut husk fiber or cocos nucifera. Although some use this for making native products‚ this study used this for an alternative bioplastic product making it more different than the usual ones. Water hyacinth‚ which is commonly found almost in some rivers and considered as another solid waste is to be used also in this project study. Although it has the same function as the coconut husk fiber‚ this is used to lessen the number or amount of water hyacinth in our

Let’s start. • Nutrition is a study of the interactions occurring between you & food. • Nutrients – about 45 substances that provide energy‚ structure or regulation of body processes. • Essential nutrients- need them‚ but can’t make them or fast enough. • Macronutrients- need in large amounts (carbohydrates‚ fats/lipids‚ proteins – provide energy/calories) • Micronutrients – need in very small amounts (vitamins‚ minerals- no energy/calories) • Phytochemicals- another category in plant food-

CHAPTER I INTRODUCTION The appendix is a closed-ended‚ narrow tube that attaches to the cecum (the first part of the colon) like a worm. (The anatomical name for the appendix‚ vermiform appendix‚ means worm-like appendage.) The inner lining of the appendix produces a small amount of mucus that flows through the appendix and into the cecum. The wall of the appendix contains lymphatic tissue that is part of the immune system for making antibodies. Like the rest of the colon‚ the wall of the

Review for Exam 1 Bio 2234 Fall 2013 1. If you have been keeping up with the material as it is presented you know this stuff. Don’t get overwhelmed by these study points. These are simply to guide you through the large amount of information. Good luck! 2. Know how negative feedback works to maintain homeostasis. Use terms effector‚ control center stimulus‚ etc to explain. Using mean arterial pressure describe how a decrease triggers reset back to normal mean arterial pressure. 3.
