biology Vocabulary Cellular Transport

Substance X is moving into a cell from an area of low concentration. Which of the following is responsible for transporting substance X into the cell?

• Proteins through the process of active transport
• Phospholipids through the process of active transport
• Proteins through the process of passive transport
• Phospholipids through the process of passive transport

Low density lipoproteins (LDL’s or bad cholesterol) are taken up “in-bulk” into the cytoplasm of a cell. This process is an example of 

• endocytosis. 
• exocytosis
• molecular transport
• osmosis. 

Examine the diagram below. The process illustrated by the neurotransmitter leaving the sending neuron is called

• endocytosis
• exocytosis
• passive transport
• active transport

The movement of substances through a cell membrane only by using the cell's energy

• active transport

• facilitated diffusion

• diffusion
