Unit 4 Report Distributing Metabolites through the body Food that we consume is composed of very complex molecules. During the digestive process these compounds are broken down into smaller and smaller subunits in preparation for use by the body as building blocks needed for the many components of the human body. In Module 3 we followed the food through the digestive system and considered the process that takes place in the digestive system. The pizza that was eaten by Matt and Maria contained ingredients

Bioscience 1 Assessment 2 (Part B) Student Name: Leana Maria S. Ragaza Student number: 18580538 Note: please ensure you have included in text references in the answers to show the source of all information Answer the following questions: Question 2: Normal carbohydrate digestion results in glucose being absorbed into the blood and elevating blood glucose levels. Why do body cells need glucose? Describe the homeostatic feedback system that would be activated in response to an elevated blood glucose

and islet cell antibodies when the body’s immune system attacks and destroys insulin producing beta cells (Nelson-Piercy‚ 2005). This affects the metabolism of fats‚ proteins and carbohydrates as insulin facilitates the transformation of glucose to glycogen‚ changes glucose to fat and stimulates the oxidation of glucose for ATP production (Marieb and Hoehn‚ 2008). Insulin helps to maintain the homeostasis of blood sugar levels‚ increasing when levels are high and decreasing when low. This works by the

Unit 5 task 3 (P5 M2 D2) – explain the concept of homeostasis‚ discuss the probable homeostatic response to changes in the internal environment during exercise‚ how homeostatic mechanisms control temperature‚ breathing and heart rate and evaluate the importance of homeostasis in maintaining healthy functioning of the body. Homeostasis Homeostasis is the maintenance of a constant internal environment in organisms. It involves volume of blood and tissue fluid within restricted limits‚ it also maintains

works a normal nine to five job. For instance‚ people try dieting and then will starve their body by not eating anything at all or just salads that will go nowhere fast. The human body needs heavy calories to burn off and produce healthy enzymes and glycogen. Specifically‚ this helps produce bigger muscles and thicker bone density. Eating nothing at all will still not help a person get healthier because the human brain needs carbohydrates and proteins to function properly. Naturally‚ eating too much

Zachary’s Story Unit 6 Case Study 1 AP2630 Rhonda Carter July 27‚ 2015 A. An ulcer starts by eroding the mucosa of the G.I. tract wall. What functions of digestion and/or reabsorption might be lost if this layer is no longer functional? What functions will be compromised if the ulcer eats through the submucosa and then the muscularis? Absorption would not happen correctly some of the ingested and secreted may seep out of the lumen. This also could create a pathway of entry for pathogens

Caffeine’s Effect on Learning and Memory Caffeine has a positive effect on learning and memory. Caffeine improves short term memory and increases reaction times. It also aids in helping children concentrate and improve their motor and memory attributes. Another effect is it enhances learning by increasing retention. Caffeine has a positive effect on learning and memory because it improves short term memory and increases reaction times. The caffeine travels to the hippocampus‚ which is the memory

Describe two examples of homeostatic systems in humans The phrase homeostasis originates from the Greek language. “Homeo” defined as “similar” and “stasis” meaning “stable”. Homeostasis is vital for us humans as it maintains equilibrium in the body‚ which may be caused due to extrinsic changes. Homeostasis happens to sustain the bodies activity‚ health and functioning. Homeostasis can occur to organs like skin‚ kidney or liver and it usually contains a system of feedback controls. The body has various

exoskeleton is a hard-outer shell that provides support and protection. The exoskeleton also helps to regulate water loss and limit the size of insect growth. The exoskeleton is made up of a composite called chitin. Chitin is a chemical relative of glycogen and cellulose. The exoskeleton is made up of three parts called the epidermis‚ basement membrane‚ and the cuticle. The cuticle is the part of the exoskeleton where most chitin concentrations occur. Bumblebee wings are formed of the same material
