Learning objectives
KNOWLEDGE AND UNDERSTANDING
The course will provide students with fundamental notions regarding cells, genetics, evolution of living organisms, structure and function of plants and animals, metabolism of carbohydrates, lipids and aminoacids, energy extraction from nutrients.
APPLYING KNOWLEDGE AND UNDERSTANDING
The course aims at providing students with the tools needed to analyze the biological and biochemical processes underlying the preparation of foods from animal and plant sources and the absorption and utilization of food nutrients.
Prerequisites
To deal with the topics of the “Biology and Biochemistry” course, students should possess a basic knowledge of Chemistry and Organic Chemistry.
