FAQs on Haemoglobin & Denaturation of Proteins Video Lecture - NEET
| 1. What is haemoglobin and what is its role in the body? |  |
Ans. Haemoglobin is a protein found in red blood cells that is responsible for carrying oxygen from the lungs to the rest of the body. It binds to oxygen in the lungs and releases it in tissues where oxygen is needed for various cellular processes.
| 2. How does denaturation affect the function of proteins? | |
Ans. Denaturation refers to the process of unfolding or altering the structure of a protein, which can disrupt its normal function. When a protein is denatured, its shape changes, leading to a loss of its specific binding properties or enzymatic activity. This can render the protein non-functional or less efficient in carrying out its intended biological roles.
| 3. What are the factors that can cause denaturation of proteins? | |
Ans. Several factors can cause denaturation of proteins, including heat, extreme pH levels (acidic or alkaline conditions), high salt concentrations, and exposure to certain chemicals or detergents. These factors disrupt the weak bonds that maintain the protein's three-dimensional structure, leading to denaturation.
| 4. Can denaturation of haemoglobin affect its ability to bind oxygen? | |
Ans. Yes, denaturation of haemoglobin can affect its ability to bind oxygen. The structure of haemoglobin is crucial for its oxygen-binding capacity, and any alteration in its shape due to denaturation can impact this ability. Denatured haemoglobin may have a reduced affinity for oxygen, leading to impaired oxygen transport in the body.
| 5. How can denaturation of haemoglobin be prevented or minimized? | |
Ans. Denaturation of haemoglobin can be prevented or minimized by avoiding extreme conditions such as high temperatures, extreme pH levels, or exposure to harsh chemicals. Additionally, maintaining a healthy lifestyle, including proper nutrition and avoiding smoking or excessive alcohol consumption, can help preserve the integrity and function of haemoglobin.
