for cell metabolism‚ including the maintenance and repair of cells and growth. In humans‚ digestion and absorption occur in the alimentary canal or gut. As the gut wall is continuous with the outside surface of the body‚ the food in the gut is considered to be outside of the body‚ the gut is specialised into different regions‚ each designed to carry out a different role in the overall processes of digestion and absorption. The human gut is a coiled‚ muscular tube extending from the mouth to the

Ad1 Digestion is the mechanical and chemical breaking down of food into smaller components‚ to a form that can be absorbed‚ for instance‚ into a blood stream. Digestion is a form of catabolism; a break down of macro food molecules to smaller ones. The digestive process also involves creating waste to be eliminated. The digestive track (gut) is a long twisting tube that starts in the mouth and ends at anus. It’s made up of a series of muscles that coordinate the movement of food and other cells that

The process of digestion seems deceptively simple‚ matter moves into the body and continues down a conveyer belt like chain of organs that break it down completely before it leaves the body. However‚ the maintenance of such a system is complex and relies on a balance of pH and helpful bacteria to maintain homeostasis. Both acidic and basic pH’s are required at various points in digestion to maintain balance during the process. Saliva in the mouth‚ the starting point of digestion‚ is only mildly acidic

mechanically broken down. An enzyme named salivary amylase breaks starch into chunks of glucose called dextrins and maltose(disaccharide maltose). Once the food reaches the stomach‚ the acid in the stomach inactivates all salivary amylase. Carbohydrate digestion is not conducted the stomach for this reason. Before the food approaches the small intestine‚ the pancreas secretes pancreatic amylase. The pancreatic amylase digests starch into maltose. The enzymes maltase‚ sucrose‚ and lactase mucosal cells

experiment in which you will investigate a digestive enzyme’s effect on digestion” Research Question: To determine the effect of enzyme concentration on the rate of digestion. This will be done by increasing the concentration of the enzyme diastase and investigate its effect on the rate of starch digestion. The rate will be determined by the amount of time it takes to completely digest the powdered starch‚ the complete digestion will be indicated by the color change of the solution by iodine. Hypothesis:

ABSTRACT Anaerobic digestion is a process that occurs in nature and produces biogas as a by-product. Biogas typically contains between 60 and 70 percent methane. This methane content makes biogas an excellent source of renewable energy to replace natural gas and other fossil
