FDSC20020 Nutritional Energy Metabolism

Academic Year 2022/2023

The main aim of this module is to introduce students to how living cells (animal and plant) can extract energy from highly reduced organic molecules (i.e. carbohydrates, fats, proteins) and convert them to a usable form of energy suitable to the functions of the living cell. Selected metabolic pathways will be covered, as will the regulation mechanisms and interactions of the metabolic pathways operative in the cell. This module will contribute to the development of the following COMPETENCIES that are CORE to your development as a professional in Food Science:

• Understanding the structure and properties of food components, including water, carbohydrates, protein, lipids, other nutrients and food additives
• Knowledge of the chemistry of changes occurring during processing, storage and utilization
• Knowledge of the principles, methods, and techniques of qualitative and quantitative physical, chemical, and biological analyses of food and food ingredients.

Learning Outcomes:

On completion of this module students should be able to: Explain how living cells can extract, transform and utilise energy from the nutrients obtained from their environment. Predict how the mammalian organism reacts to various states of nutrition, which it may be subjected to over a period. Assess the role, mode of action and interaction of various hormones involved in nutrient metabolism.

Approaches to Teaching and Learning:
The module content is delivered via a series of lectures at the end of each lecture a series of multiple choice questions are addressed based on the content of the lecture. Two in term MCQ's (not negatively marked) are held which contribute 10% each to the final marks and a tutorial going through questions similar to those on the MCQ is held after each MCQ. Student will complete 4 labs (which may be online or in person) with experiments designed to align with and compliment the lecture material. 1 week after the lab the students hand in a worksheet which is corrected and returned after 2 weeks with a breakdown of where errors have occurred. Each worksheet contributes 5% of the final marks (20% overall). The final exam is worth 60% of the final mark and it is a MCQ (not negatively marked).

Feedback Strategy/Strategies

• Feedback individually to students, post-assessment
• Group/class feedback, post-assessment
• Online automated feedback

How will my Feedback be Delivered?

For the lab components students receive feedback in the form of a breakdown of each question on a worksheet with a commentary on where errors have occurred within 2 weeks after handing in the worksheet. For the in term MCQ's students receive their mark within 7 days and an in-class tutorial is held in which questions on the MCQ are addressed. A series of of online MCQ's quizzes are also available in which the student is told whether or not they have given the correct answer. At the end of each lecture the module co-coordinator goes through a number of MCQ questions based on the lecture topic.
