Can someone help me with this problem, it’s letter C.Thanks a lot BIOL350 CELL BIOLOGY TAKE-HOME 1 (100pts) Spring 2018 SFSU ID C. (10pts) Vesicles in Set C contain a novel transport protein that uses a Ca-electrochemical gradient to drive glucose transport against its concentration gradient. You wish to answer the question You have a method to monitor glucose movement into vesicles, and you can set the initial concentrations of glucose and Ca+-ions inside and outside the vesicles. Using these tools, design an experimental plan to answer the underlined question. Be sure to include: Initial conditions with relative concentrations of Ca2 and glucose inside and outside of the vesicles - How you would interpret results from your experiments to answer the underlined question
Explanation / Answer
A transport protein (variously referred to as a transmembrane pump, transporter, escort protein, acid transport protein, cation transport protein, or anion transport protein) is a protein that serves the function of moving other materials within an organism.
Transport proteins function in both active and passive transport to move molecules across the plasma membrane. These channel proteins are responsible for bringing in ions and other small molecules into the cell. It's important to remember that each channel protein can only bring in a specific molecule.
A symporter is an integral membrane protein that is involved in the transport of many differing types of molecules across the cell membrane. The symporter works in the plasma membrane and molecules are transported across the cell membrane at the same time, and is, therefore, a type of cotransporter.
An antiporter (also called exchanger or counter-transporter) is a cotransporter and integral membrane protein involved in secondary active transport of two or more different molecules or ions across a phospholipid membrane such as the plasma membrane in opposite directions.
Any particle moves from its region of higher concentration to lower concentration.
If concentration of Glucose is more inside vesicle, then it will start moving outside and vice versa. This transport will not require any energy in form of ATP. This will be passive movement across the membrane.
If we wish to move Glucose against the concentration gradient i.e. from a region of lower concentration to a region of higher concentration then energy will be required in form of ATP. Such movement is known as active transport of molecules.
If both calcium ion and Glucose are moving along the concentration gradient and let their concentration is more outside the vesicle , then their altogether movement inside the vesicle will known as symport.
If Glucose is moving inside and calcium ion outside or vice versa then it will be known as antiport.
