enzymes can be used over and over again. The substrates fit into the enzyme like a key fits into a lock (3). Enzymes have other functions as well‚ for example enzymes play a big role in your stomach and intestines. Enzymes such as protease‚ lipase‚ and amylase can break up fat‚ oil and starches from our daily food. How Does It Work? Enzymes are proteins‚ which act with a given compound (the substrate) to produce a complex‚ which then forms the products of the reaction.(1) Enzymes

Regulatory proteins control cellular metabolism in a way that cells throughout the body can have the right amount of glucose in the blood. A common protein is an enzyme; in cells they speed up chemical reactions. For an example‚ “amylase is an enzyme that speeds up the breakdown of starch in the mouth and small intestine” pg 28. All proteins are made up of amino acids. There about 20 different amino acids that is found in cells. A chain of two of more amino acids is called a peptide and the bond between the

Concentarion ENZYME LAB Introduction- Enzymes are proteins that speed up the rate of reactions in living things. In this lab‚ we will perform four experiments exploring the way enzymes work. PART A: pH SPECIFICITY Every enzyme has a specific pH at which it works best. In this section‚ you will determine which pH is best for the enzyme‚ catalase. Living tissues produce the enzyme catalase‚ which is able to break down hydrogen peroxide into oxygen gas and water. The reaction is

when we see it we begin to salivate‚ we have glands‚ three big glands that are going to produce saliva that is going to empty into our mouth. Now the saliva has water in it but it mostly has mucus and also an enzyme called amylase. And amylase breaks down starch (amylose starch) and so it’s going to break down‚ or start to break down the carbohydrate. So basically are teeth

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-

experiment aims to observe if simpler substrates makes the rate of cellular respiration faster. Using yeast‚ smith fermentation tubes and different substrates namely‚ starch‚ lactose‚ sucrose‚ glucose and fructose‚ which are from different kinds of carbohydrates‚ ranging from the simplest sugars glucose and fructose to the polysaccharide starch and water as the control‚ the hypothesis was tested. With the span of thirty minutes with five-minute intervals‚ the height of carbon dioxide trapped in the tube
