Description The module examines the biological role of macronutrients and their metabolism by integrating basic knowledge in physiology, biochemistry, cell and molecular biology. | |||||||||||||||||||||||||||||||||||||||
|
Learning Outcomes 1. Relate the principles of biochemistry and physiology to the science of nutrition 2. Describe the structure, function, digestion and absorption of carbohydrates, fats and proteins 3. Describe the key metabolic pathways involved in the metabolism of carbohydrates, fats, proteins and ketones in the fed and fasted state and, during exercise of different intensities and duration 4. Develop an appreciation for the complex molecular signaling pathways that regulate whole body metabolism is response to a variety of perturbations 5. Interpret nutritional research and debate controversial or evolving nutritional issues | |||||||||||||||||||||||||||||||||||||||
