Explore Transport Mechanisms in Cells

Front

What is happening in the diagram and what is this process called?

Back

Large particles are entering the cell through endocytosis.

Answer explanation

This image shows particles being engulfed and brought IN to the cell. So it is endocytosis!

Front

Use the diagram to answer the following question. What process is occurring and what is missing from this diagram?

Back

The diagram is showing active transport because the molecules are moving from low concentration to high concentration, but energy should be included in the diagram.

Answer explanation

Active transport forces molecules to move from low concentration to high concentration and it requires the use of energy. This is going up or against the concentration gradient!

Front

Mechanism used by streptococcus pneumoniae to pump antibiotics out of their cells.

Back

active transport

Answer explanation

Whenever a cell is 'pump'ing a molecule it requires energy and will be active transport!

Front

Which of the following describes active transport correctly?

Back

Active transport uses ATP energy to move molecules against the concentration gradient (from low to high).

Answer explanation

Remember active transport is like going up a slide!

Front

D represents a semipermeable membrane. What does that mean?

Back

Some things can cross the membrane and others cannot

Front

What is the difference in the amount of a substance on either side of the cell membrane called?

Back

concentration gradient

Front

What is it called when the concentration of a substance is the same on both sides of the cell membrane?

Back

equilibrium
