The guide was prepared for the students of the medical
faculty, who study according to the specialty “General
Medicine” in English language. The book may also be helpful
for the students of Dentistry and Pharmacy faculties.
The guide was approved and recommended for publication
by the Scientific Council of the Danylo Halytsky Lviv National
Medical University.
, FOREWORD
Biological chemistry is a fundamental medical discipline. The
understanding of the processes of proteins, carbohydrates, lipids
and water turnover as well as the role of vitamins, trace elements
and regulatory mechanisms in the organism is the background for
the interpretation of the laboratory indices in health and disease
in clinical practice.
The obtaining of the proper knowledge, based on the use of
the different methodological approaches, in particular test control,
is one of the main tutorial elements for the students of the higher
educational medical institutions worldwide.
Aimed at the improvement of the students’ knowledge and
assisting them in preparation to the practical classes, final exam
and Integrated State Qualification Exam, that contains Krok-1, the
department prepared a guide, which includes main multiple
choice questions according to the Biochemistry course programe.
The guide was elaborated according to educational and
qualification characteristics and educational-professional
programmes of the training of specialists in compliance with the
Standard of the Higher Education of Ukraine (the second masters’
level).
The multiple choice questions are distributed into 2 main
chapters according to the programme of 2 semesters, matching
the title and content of the relevant topic. Hence, the first semester
chapter includes multiple choice questions to 16 topics, devoted
to general assignments of biochemistry, enzymology,
bioenergetics, turnover of carbohydrates, lipids and amino acids.
The 2nd chapter contains 18 topics on the study of DNA and RNA
composition, processes of DNA replication, RNA transcription,
molecular mechanisms of the effect of hormones, digestion and
vitaminology as well as issues of functional biochemistry, e.g.
biochemistry of blood, liver, water and minerals turnover,
biochemical composition of muscular and connective tissues.
The authors hope that the use of this guide will improve the
level of students’ knowledge and score in exams.
