JNTU B.Pharmacy I Year HUMAN ANATOMY AND PHYSIOLOGY-I Previous Question Paper (January-2018 - R17)
Note: This question paper contains two parts A and B. Part A is compulsory which carries 25 marks. Answer all questions in Part A. Part B consists of 5 Units. Answer any one full question from each unit. Each question carries 10 marks.
PART A
Discuss the transport across the cell membrane.
Answer
Transport across the cell membrane occurs via passive processes (diffusion, osmosis, and facilitated diffusion), which require no energy, and active processes (active transport, endocytosis, and exocytosis), which require ATP to move substances against a concentration gradient.
What is homeostasis? Discuss in brief the homeostatic mechanism.
Answer
Homeostasis is the maintenance of a relatively stable internal environment despite external changes. The mechanism involves a receptor that detects a stimulus, a control center (such as the brain) that processes the information, and an effector that produces a response to restore balance, typically through negative feedback loops.
