A protein called insulin is responsible for controlling how much sugar is in our blood. When insulin is present, cells take up sugar from the blood, controlling our blood-sugar levels and keeping our body in balance. Some people with diabetes don't make enough insulin. What would be a problem if cells could no longer produce the protein insulin? A - People would have too low blood sugar. B - Nothing would happen--their blood sugar would remain the same. C - They would not be able to digest sugar anymore. D - People would have too high blood sugar.
Proteins
We generally tend to think of proteins only from a dietary lens, as a component of what we eat. However, they are among the most important and abundant organic macromolecules in the human body, with diverse structures and functions. Every cell contains thousands and thousands of proteins, each with specific functions. Some help in the formation of cellular membrane or walls, some help the cell to move, others act as messages or signals and flow seamlessly from one cell to another, carrying information.
Protein Expression
The method by which living organisms synthesize proteins and further modify and regulate them is called protein expression. Protein expression plays a significant role in several types of research and is highly utilized in molecular biology, biochemistry, and protein research laboratories.
