Saliva Lab Since the amylase enzyme is present in saliva‚ starch digestion begins in the mouth. Salivary amylase changes the polysaccharide starch into many disaccharide molecules of maltase (a simple sugar) which are further broken down into glucose units by maltase enzyme in the As stated above‚ saliva contains the amylase enzyme which begins the breakdown of starches. The efficiency of starch digestion by amylase can be measured by how much simple sugar it produces under

Lipid Digestion The process of mastication is our only conscious act in the digestion of the foods we consume. After that‚ it’s out of sight‚ out of mind; but should it be? What does it take to transform that last swallow into the energy our body needs to sustain itself? In the case of lipid digestion‚ the real magic occurs throughout the gastrointestinal tract with a synergistic collaboration from the accessory organs: the liver‚ gallbladder and pancreas. Understanding the whole process of digestion

snake meat can be sold from USD 16 to 29. Therefore‚ meat could be another product of the snake farm. Snake venom is highly modified saliva that is produced by special glands of certain species of snakes. The gland which secretes the zootoxin is a modification of the parotid salivary gland of other vertebrates‚ and is usually situated on each side of the head below and behind the eye‚ invested in a muscular sheath. It is provided with large alveoli in which the venom

In this assignment I will explain the physiology of two named body systems in relation to energy metabolism in the body. I will be explaining two body systems these are Respiratory system and Digestive system. Energy According to Wright (2007)‚ we need energy for everything we do. Energy can be found in different forms including chemical energy‚ electrical energy‚ thermal energy‚ radiant energy‚ mechanical energy and nuclear energy. We use energy all the time including when we are sleeping. We

Defn:Dengue Haemorrhagic Fever(DHF) are acute febrile diseases transmitted by mosquitoes‚ which occur in the tropics‚ can be life-threatening‚ and are caused by four closely related virus serotypes of the genus Flavivirus‚ family Flaviviridae.It was identified and named in 1779. It is also known as breakbone fever‚ since it can be extremely painful. Causative Agent: .
