Digestive enzyme

HUMAN DIGESTIVE SYSTEM 1.0 Introduction Humans need to obtain nutrients by taking in different kinds of food. The food we eat needs to be broken down into simple, soluble forms before it can be absorbed by our body. The human digestive system has many process. It contains different stages and works in different organs. It starts at the oral cavity and ends at the anus. The digestive system involves five main processes in the digestive system; ingestion, digestion, absorption, assimilation and…

that also play a very important role into the cell as far development goes. Many of the organelles operate off of other to maintain its specific duties with the human body. One in particular are considered to be peroxisomes. Peroxisomes have digestive enzymes in relations to lysosomes, but they have special bodies that allow it to work in low level regions in which wouldn’t be supported elsewhere inside of the specific cell. Peroxisomes break down chains of long fatty acids, amino acids, etc.…

1. Which components of the digestive system are GI tract organs, and which are accessory digestive organs? The GI tract organs includes; The mouth, pharynx, esophagus, stomach, small intestine, and large intestine. The accessory digestive organs include; The tongue, teeth, salivary glands, liver, gall bladder, and the pancreas 2. Which organs of the digestive system come in contact with food, and what are some of their digestive functions? Mouth is used for ingestion of food. Saliva…

the enzyme concentration versus the reaction time of an enzymatic reaction, and the effects of the reactants and products concentration direction of the reaction. Specifically, in this lab the enzymes salivary amylase and phosphorylase were looked at the effect of the enzyme concentration versus the reaction time of an enzymatic reaction were observed by the iodine test along with the benedict’s test. Enzymes are known as biological molecules which catalyze different reactions and all enzymes…

duct cells. These cellular clusters make up the exocrine portion of the pancreas that produce and deliver digestive pro-enzymes, pancreatic fluid, and electrolytes into the gastrointestinal tract. Acinar cells synthesize and secrete zymogen granules that are released at the cell apex by exocytosis into the ductal system. Multiple defense mechanisms exist to prevent premature intra-acinar enzyme activation; a key feature of acute pancreatitis, by compartmentalization of zymogen granules from…

called glucagon. The glucagon is released into the bloodstream and sent to the liver. The glucagon binds to its receptor/target cells, it also changes the shape of the receptor and activates enzyme activity inside the cell. Chemical reactions as a result of this process lead to the production of the same enzyme that is used to convert glucose to glycogen, phosphorylase. The phosphorylase catalyses the reaction of glycogen back to glucose, this process is called Glycogenesis. As the levels of…

facilitates the absorption of calcium from the intestinal walls. 7.Receptor Located on the outer part of the cells, receptor proteins control the substances that enter and leave the cells, including water and nutrients. Some receptors activate enzymes, while others stimulate endocrine glands to secrete epinephrine and insulin to regulate blood sugar levels. 8.Contractile Also known as motor proteins, contractile proteins regulate the strength and speed of heart and muscle…

amino acid breakdown and will use the energy from deaminating amino acids. Phenylalanine becomes phenylpyruvic acid and is detected by acetic iron chloride, which turned the plate green when added. If the bacteria have the phenylalanine deaminase enzyme, the bacteria will become green and considered a positive result. Although not actually done in class, the oxidase is also an important test in microbe identification. In this test, cytochrome c oxidase is used as an electron carrier and become…

The pancreas is one of the main organs in our body that is used for digestion of food1. The exocrine function of the pancreas is responsible for secreting digestive enzymes that are then used to digest the food we eat, leading to uptake of nutrients from the food, by the body1. Exocrine Pancreatic Insufficiency is a defect in those digestive enzymes1. This defect leads to the inability to break down food and therefore, difficulty absorbing the nutrients from food1. When the body is not able to…

acid by pancreatic enzymes prior to absorption. First, the chicken is mechanically digested in the mouth when chewed and breaks it into smaller pieces. The partially digested chicken travels to the stomach and begins digesting with the action of enzymes called pepsin (Primal Pictures). Pepsin breaks the bonds that hold the protein molecule together. Once these bonds have been broken they form a chain of amino acids that are linked together called polypeptides (Primal…
