What else can I help you with?
Are both zinc and iron transported in the blood by a fat carrier?
Zinc is primarily transported in the blood by a protein carrier called albumin, while iron is typically transported by a protein called transferrin. These carriers help maintain the proper levels of these minerals in the blood and deliver them to the cells that need them.
Through what type of proteins does active transport occur?
Active transport occurs through carrier proteins that pump molecules against their concentration gradient using energy from ATP. These carrier proteins undergo conformational changes to transport molecules across the cell membrane.
How many types of molecules can a carrier protein transport?
There are nine main types of energy. There are three main types of energy carriers; ATP, NADPH, and NADH. An energy carrier is a incredible molecule that, in itself, sends, receives, and carries.
What changes occur to a carrier protein once it binds to its target molecules?
the carrier protein changes shape to release the molecule inside of a cell
What happens in each of the three main parts of facilitated diffusion?
Binding: Molecules from the extracellular environment bind to the carrier protein on the cell membrane. Transportation: The carrier protein undergoes a conformational change, allowing the molecules to pass through the membrane. Release: Once inside the cell, the molecules are released from the carrier protein and the protein returns to its original conformation for further transport.
Glucose and no other sugar is transported into cells by protein carrier molecules in the cell surface membrane. How do carrier molecules specifically recognize glucose?
Carrier molecules have specific binding sites that are complementary to the structure of glucose molecules. This allows the carrier molecules to selectively recognize and transport glucose across the cell membrane while excluding other sugars. The specificity of recognition is determined by the shape, size, and chemical properties of both the carrier molecule and the glucose molecule.

What is a carrier protein?
A carrier protein is a type of protein that helps transport specific molecules across cell membranes. These proteins bind to molecules on one side of the membrane and release them on the other side, facilitating their movement into or out of cells. Carrier proteins play a crucial role in maintaining cellular function by regulating the transport of essential molecules.
Through what type of proteins does active transport occur?
Active transport occurs through carrier proteins that pump molecules against their concentration gradient using energy from ATP. These carrier proteins undergo conformational changes to transport molecules across the cell membrane.

Which is a factor that determies whether a mole can cross a cell membrane?
Lipid solubility determines if it will diffuse across. The presence of specific protein carrier molecules determines if it will be transported across the membrane.
What does a carrier protein do in the process of transporting molecules across a cell membrane?
A carrier protein helps transport molecules across a cell membrane by binding to specific molecules and changing shape to move them across the membrane.
What changes occur to a carrier protein once it binds to its target molecules?
the carrier protein changes shape to release the molecule inside of a cell
What are the protein molecules in a cell membrane that assist in cell transport?
Protein molecules are responsible for membrane transport. In passive transport diffusion is the phenomenon in which molecules flow naturally from areas of high concentration to lower concentrations.
Does facilitated diffusion require a carrier or channel protein for the movement of molecules across the cell membrane?
Yes, facilitated diffusion requires a carrier or channel protein for the movement of molecules across the cell membrane.
What happens in each of the three main parts of facilitated diffusion?
Binding: Molecules from the extracellular environment bind to the carrier protein on the cell membrane. Transportation: The carrier protein undergoes a conformational change, allowing the molecules to pass through the membrane. Release: Once inside the cell, the molecules are released from the carrier protein and the protein returns to its original conformation for further transport.
Can you give me an example of a protein made on the rough ER that is transported out of the cell?
