Theory Examination (Semester- II) 2015-16 REMEDIAL BIOLOGY-II

This is a 3-hour Theory Examination for NBT-201 / EBT-201 / BT-201, carrying 100 marks. The paper is divided into three sections – A, B, and C, and students must answer questions from all sections as per instructions. The exam covers fundamental topics in microbiology, cell biology, biochemistry, metabolism, immunology, respiration, and human health.

Section – A (20 Marks)

Section A contains 10 very short-answer questions, each carrying 2 marks. Students must answer all parts.
These questions focus on basic definitions and short notes related to:

lichens

algae

structure of bacteriophage

aerobic vs anaerobic respiration

meaning of metabolism

ATP and its importance

full forms of MTP & STDs

definition of immunology

labelled diagram of a prokaryotic cell

definition of enzyme

This section tests quick recall and fundamental understanding of biological terms and structures.

Section – B (50 Marks)

Section B contains 8 descriptive questions, out of which any five must be attempted. Each question carries 10 marks.
These questions require explanations, diagrams, and short descriptions. Topics include:

lipid catabolism

size, shape, and arrangement of bacteria

ultra-structure of mitochondria

differences between glycolysis and Krebs cycle

Gram-positive vs Gram-negative bacteria

factors affecting respiration

metabolic diversity

population explosion and its harmful effects

This section checks the student’s ability to explain biological processes clearly with proper scientific understanding.

Section – C (30 Marks)

Section C contains three long-answer questions, of which any two must be attempted. Each question carries 15 marks.
These questions require detailed explanations and diagrams. Topics include:

cancer and its treatment methods

prokaryotic and eukaryotic cells

detailed description of glycolysis

oxidative phosphorylation

This section evaluates the student’s deep understanding, analytical skills, and ability to describe complex biological processes.

Overall Summary

This question paper tests knowledge of:

basic microbiology

metabolism and respiration

cell structure and function

immunology and enzymes

metabolic pathways like glycolysis and oxidative phosphorylation

human diseases and population issues

Section A checks basic definitions,
Section B checks explanation and process understanding,
Section C checks in-depth knowledge of core biological topics.
