Digestion/ Absorption and Homeostasis In order to survive‚ our bodies must bring in energy and nutrients for the cells of the body through eating and digestion of food. To be carried to the cells of the body by the blood stream‚ food must be broken down to molecules. This breaking down of food into molecules‚ small enough to be absorbed into and carried through the blood stream‚ is carried out by the digestive system through the process of digestion and absorption. Digestion is the process of
Free Digestion
Defn. of Digestion: the process whereby a biological entity processes a substance‚ in order to chemically convert the substance into nutrients. It usually involves mechanical manipulation and chemical action. Mechanical Digestion What is it? This type of digestion involves the mixing‚ grinding or crushing of large pieces of food into smaller places. Why does it take place? So that the food we consume is broken down into smaller pieces before we swallow it which in turn makes process of

For each tube‚ explain why it would have exhibited that that level of digestion. Answer: |Tube with greatest amount of digestion: | |Test Tube 4

Bread contains starch. The starch content in bread is derived from the starchy endosperm of wheat. Refined breads have the bran and germ removed from the wheat in order to produce softer‚ silkier flour. there is a lot more food containing starch like: Starchy foods such as potatoes‚ bread‚ cereals‚ rice and pasta should make up about a third of the food you eat. Where you can‚ choose wholegrain varieties‚ or eat potatoes with their skins on for more fibre. Starch is the most common form of

Charlene Villanueva - Biology Charlene Villanueva - Biology Starch‚ Glycogen and Cellulose Independent Research A polysaccharide is a long chain of monosaccharide molecules‚ held by glycosidic bonds. They are usually not sweet in taste‚ insoluble in water and often do not produce crystals when water is taken out. Starch Starch is a complex solid carbohydrate‚ consisting glucose molecules held together by glycosidic bonds. It is a storage polysaccharide. They can be found in fruits‚ seeds‚ roots

The Effect and Rate of the Enzyme Amylase on Starch Abstract Assessing reaction speed of the enzyme amylase can be measured by the amount of glucose and maltose produced during given time intervals. I hypothesized that‚ if the reaction time is longer‚ then the amount of amylase will be larger. Enzymes are specific in their match of substrates they will breakdown – similar to a key and its lock. Since amylase is the only enzyme that breaks down starch‚ the procedure was effective and gave clear

Focused Question: How can one determine the presence of glucose‚ starch‚ lipid‚ and protein in various samples? Pre-lab Questions: • Glucose is a monosaccharide. What does this mean? A monosaccaride is a carbohydrate molecule with three to seven carbon atoms with the corresponding number of hydrogen and oxygen atoms. • Proteins are made of amino acids. What atom is present in an amino acid that is not present in a sugar molecule? One nitrogen atom is present per molecule in an amino acid

Biology Form Four Digestion Digestion is the process by which food is broken down from complex insoluble substances into simple soluble substances. There are two types of digestion – chemical digestion and mechanical digestion. Mechanical digestion involves breaking up large pieces of food into smaller pieces. This provides a large surface area for the action of enzymes on food. There is no change to the chemical composition of food during mechanical digestion. Mechanical digestion occurs in the
