First of all the cheese sandwich is chewed by the teeth and is ingested. The enzyme amylase in the saliva which breaks down substances like starch into glucose. This makes it easier to swallow. Then it passes through the gullet‚ also called the oesophagus which is like a long tube located in the throat. The walls of the gullet contract

Most abundant organic molecule in nature a) 3 major classes: Monosaccharides – simple sugar – polyhydroxy aldehyde or ketone; represent individual sugar Oligosaccharides – consist of short chains of monosaccharide units joined together by covalent bonds; 2-10 strings of sugar Polysaccharides – long chains having hundreds or thousands of monosaccharide units b) Functions: Provide energy thru oxidation – glucose oxidized for energy Supply carbon

PROTEIN Prior to completing the lab experiment‚ it was predicted that whipping cream‚ soy milk‚ and the flour solution would all contain proteins. Looking back at the collected observations it can be concluded that the hypothesized statements were all deemed accurate. However‚ corn syrup was the only substance that did not test positive for proteins. This abnormality was researched‚ and it is now clear why only three out of the four substances tested positive for proteins. To start‚ it was hypothesized

Humor and Healing: The Mind-Body Connection "As it is not proper to cure the eyes without the head‚ nor the head without the body; so neither is it proper to cure the body without the soul." Socrates(Cousins‚ 56) The word‚ to heal‚ comes from the root word "haelen" which means to make whole. Bringing together the body‚ mind and spirit can be healing. The word humor itself is a word of many meanings. The root of the word is "umor" meaning liquid or fluid (Moyers‚ 221). In the Middle Ages‚ humor

Respiration‚ digestion and rocks Respiration Respiration is a chemical reaction that happens in all living cells. It is the way that energy is released from glucose‚ for our cells to use to keep us functioning. Remember that respiration is not the same as breathing (which is properly called ventilation). The glucose and oxygen react together in the cells to produce carbon dioxide and water. The reaction is called aerobic respiration because oxygen from the air is needed for it to work. Digestion

Principle: This test was designed to detect B. anthracis antigens in the tissues of animals being utilized in animal by-products and thereby to reveal when these products contained ingredients originating from animals that had died of anthrax. The thermostable antigens involved are common to other

The presence of blue color upon the adding of iodine indicates that starch is not hydrolyzed. C) Gelatin Hydrolysis Gelatin is the convenient

To ensure the results were accurate‚ I made sure I accurately measured out the amylase and starch solutions for each experiment. This is because‚ if I had the wrong amounts‚ I would not get a valid conclusion‚ as I will not know whether my results are affected by the concentration of starch‚ or whether the results I got were due to
