Learning outcomes
Basic knowledge of the role of elements in biological systems. Understanding of biological reactions and membrane transport processes.
KNOWLEDGE: after passing the course, the student knows and understands:
K_W01 – has extended knowledge of the place of chemistry in the system of exact and natural sciences and of its importance for the development of humanity.
K_W02 – knows the fundamentals of biochemistry and understands the significance of chemical phenomena in processes occurring in living nature.
K_W04 – knows the aspects of construction and operation of modern measuring and analytical apparatus supporting scientific research in chemistry.
K_W11 – has extended knowledge of occupational health and safety, in particular knows the principles of safe handling of chemicals, as well as the selection and disposal of chemical waste; knows basic legal regulations related to chemical safety and is able to responsibly apply this knowledge in professional work, including risk assessment.
SKILLS: After completing the course, the student is able to:
K_U01 – use biochemical techniques and apply simple biological processes in chemistry and technology.
K_U08 – demonstrate advanced knowledge and skills enabling the effective use of professional literature, databases and other information sources, as well as the ability to critically assess the reliability of obtained information.
K_U10 – present the results of their own research in the form of an independently prepared written study (report, thesis) containing a description and justification of the aim of the work, the adopted methodology, results, and a discussion of their significance in comparison with other similar studies.
K_U12 – present, in a way understandable also to non-specialists, the results of the most important discoveries in chemistry and related sciences.
K_U13 – independently acquire knowledge and develop professional skills using various sources (written and electronic), including foreign-language sources.
SOCIAL COMPETENCES: After completing the course, the student is ready to:
K_K01 – understand the need for continuous learning and is able to independently search for information in the literature (including foreign-language sources) and seek expert advice.
