do protiens carry oxygen in human blood?
6 answers
No, proteins do not carry oxygen in human blood. Oxygen is primarily carried by red blood cells through a protein called hemoglobin. Hemoglobin binds to oxygen in the lungs and transports it to the body's tissues and organs. Proteins in the blood play other important roles such as regulating immune responses and transporting nutrients and waste products.
are thier strucutres related to thier fuction?
Yes, the structure of proteins is closely related to their function. Proteins are made up of amino acids that are arranged in specific sequences to form unique three-dimensional shapes. This shape determines the protein's function and how it interacts with other molecules in the body. For example, the structure of hemoglobin allows it to bind to and transport oxygen. Any changes in the protein's structure, such as through mutations or denaturation, can affect its ability to function correctly. Overall, the structure-function relationship is crucial for understanding how proteins carry out their various roles in the body.
They are created by mutations in DNA?
Yes, proteins are created based on the information encoded in DNA. DNA contains the genetic instructions for building proteins in the form of genes. Genes are specific sequences of DNA that code for the production of a particular protein. When a gene is transcribed into messenger RNA (mRNA) and translated by the cellular machinery, a specific sequence of amino acids is assembled to form a protein.
Mutations in DNA can alter the sequence of amino acids in a protein, leading to changes in its structure and function. Some mutations can have harmful effects, such as causing genetic diseases or disorders, while others may have neutral or even beneficial effects. Mutations are a natural part of genetic variation and can drive evolution by introducing new protein functions or traits into a population over time.
