Active Cellular Transport Quiz

What is active cellular transport?

• The movement of particles from an area of high concentration to an area of low concentration

• The movement of particles from an area of low concentration to an area of high concentration

• The movement of particles without the use of energy

• The movement of particles through vesicles

Which molecule is primarily used as an energy source in active cellular transport?

• ADP

• Pi (inorganic phosphate)

• ATP

• Glucose

What are the three types of active cellular transport?

• Primary, secondary, and tertiary

• Endocytosis, exocytosis, and vesicle transport

• Molecular pumps, endocytosis, and exocytosis

• Symport, antiport, and receptor-mediated endocytosis

Which type of active transport utilizes ATP to transport molecules across a membrane against their concentration gradient?

• Primary active transport

• Secondary active transport

• Molecular pumps

• Exocytosis

What is the function of the Sodium/Potassium Pump?

• To move sodium ions out of the cell and potassium ions into the cell

• To move sodium ions into the cell and potassium ions out of the cell

• To move glucose into the cell

• To move water out of the cell

How does the Sodium/Potassium Pump utilize ATP?

• ATP binds to the pump and releases sodium ions out of the cell

• ATP binds to the pump and releases potassium ions into the cell

• ATP binds to the pump and releases glucose into the cell

• ATP binds to the pump and releases water out of the cell

What is the process called when sodium ions enter the cell and bring a glucose molecule along with them?

• Phagocytosis

• Pinocytosis

• Receptor-mediated endocytosis

• Symport

What is the difference between a symport and an antiport?

• A symport pumps molecules in the same direction, while an antiport pumps them in opposite directions

• A symport pumps molecules out of the cell, while an antiport pumps them into the cell

• A symport pumps glucose into the cell, while an antiport pumps sodium ions out of the cell

• A symport pumps sodium ions into the cell, while an antiport pumps potassium ions out of the cell

What is the process called when large molecules are captured from outside the cell by surrounding them with the cell membrane?

• Phagocytosis

• Pinocytosis

• Receptor-mediated endocytosis

• Exocytosis

Which type of endocytosis involves taking in specific molecules by binding them to receptors in a coated pit on the cell's surface?

• Phagocytosis

• Pinocytosis

• Receptor-mediated endocytosis

• Symport
