What is the primary difference between regular active transport and passive transport?

1

What molecules are used to fuel the process of active transport?

1

Sort the following

  • Involves the movement of water
  • The goal is to reach dynamic equilibrium
  • Involves the use of a protein pump
  • Involves solutes moving through a protein channel without the use of energy
  • Involves the movement of solutes from areas of low concentration to areas of high concentration
  • Moves molecules against the concentration
  • Does not require energy
  • Involves the movement of solutes from areas of high concentration to areas of low concentration
  • Simple diffusion
  • Facilitated diffusion
  • Osmosis
  • "Regular" active transport
1

What is the meaning of endocytosis in the context of active membrane transport?

1

Why is ATP needed in regular active transport?

1

In what process do cells expel waste materials or secrete substances?

1

Identify the type of active transport each of the following fall under.

  • Release of many large digestive enzymes
  • Uptake of a large amount of cholesterol
  • Pumping glucose into a cell
  • Sodium-Potassium Pump
  • Exocytosis
  • Endocytosis
  • Regular Active Transport
1

Categorize these processes as either using ATP directly, vesicles, or neither for active transport.

  • Sodium-Potassium Pump
  • Release of many neurotransmitters
  • Facilitated diffusion
  • Proton pump
  • Uses ATP directly
  • Uses vesicles
  • Uses neither

What happens in endocytosis?

The final questions will refer to the image below. Note: do not address osmosis in this answer! If there is not a protein channel or pump drawn do not assume that it is present.
