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.
what type of glucose transport protein is found mainly in neurons and the placenta?
SGLUT-1
GLUT-2
GLUT-3
GLUT-4
GLUT-5
Glucose is very important source of energy for all body cells. But Brain cells( neurons) mainly depend on glucose for generating energy in the form of ATP for maintaining and controlling optimal functioning of the body.
Glucose requires transport proteins for its transport across the membrane. GLUT transport proteins are found embedded in the plasma membrane.
GLUT4 found in adipocytes and skeletal and cardiac muscle.
GLUT2 is a facilitative glucose transporter located found in liver, pancreatic, intestinal, kidney cells as well as in the portal and the hypothalamus areas.
GLUT5 is a fructose transporter found in the small intestine
GLUT3 transport proteins are found mainly in the brain where they are responsible for glucose uptake into neurons( brain cells).
