Understanding the functions of the body systems associated with energy metabolism Energy is used for many of the bodily functions including the ability to ventilate‚ respire‚ move‚ grow and repair. The first law of thermo dynamics states that energy can be transformed from one state to another but cannot be lost. Energy comes in many forms‚ some of these are as follows:- Light Sound Kinetic Heat Chemical In accordance with the First Law an example of how energy can transform is when the sun creates

experiment. What effect did pH level have on the enzyme? It partially allowed the enzyme to do its job because there were positive signs of both starch and its reducing sugars. What effect did boiling and freezing have on the activity of amylase? Boiling did not allow the breakdown of starch because the reduced sugars were not present and the starch was where the freezing showed a ++ for the reducing sugars and a negative result in the starch showing that it reduced the starch.

organ of the alimentary canal The alimentary canal includes the mouth‚ pharynx‚ esophagus‚ stomach‚ small intestine‚ large intestine‚ andanal canal Mouth Food enters the digestive tract through the mouth. The labia (lips) protect its anterior opening‚ the cheeks form its lateral walls‚ the hard palate forms its anterior roof‚ and the soft palate forms its posterior roof. The space between the lips and cheeks externally and the teeth and gums internally is the vestibule. The area contained by

Amylase is found in the saliva of humans and is responsible for the first step in breaking down starch. Starch is a polysaccharide composed of a large number glucose monomers joined together. Amylase breaks down starch by separating the glucose molecules into maltose‚ which is a two glucose-unit compound. (Morgan‚ 2008) During this experiment we investigated the influence of pH on the activity of the enzyme Amylase. We are able to use the fact that when I2KI

Throughout the course of human history‚ hunters-gatherers remained their existences in every stage of evolution as they are the fundamental response units when it comes to food. By the region or area different hunters-gatherers occupied‚ different food source or species of food were limited by the set boundary of each tribe. Oftentimes hunters-gatherers equipped with advanced technology at their time to lower the amount of energy needed to lay their hand on their prey. Bow for example is a piece

Metabolism refers to all the chemical reactions in the body of a cell or organism to keep it alive. Metabolism converts the nutrients from the food we eat in to vital energy which the body needs to carry out daily activities. The respiratory system‚ cardiovascular system and the digestive system are the three body systems that are involved with energy metabolism. There are two kinds of activities involved with metabolism processes‚ these are; building up of body tissues and energy stores and the

Physical Warmth‚ Interpersonal Warmth and Sympathetic Nervous System Activity La Trobe University‚ Melbourne Word Count: 2481 Abstract Convergent lines of evidence indicate that introducing a physically warm stimulus‚ such as a heat pack‚ results in individuals interpreting a target person as “warmer”. Neurobiological mechanisms responsible for thermoregulation may be shared by mechanisms responsible for interpretation of interpersonal warmth‚ and may be connected to sympathetic nervous system
