Active Transport and Osmosis

What are 3 types of active transport?

• Riding a bike, Running through the mountains, walking on the beach

• Osmosis, Diffusion, Facilitated Diffusion

• Sodium/potassium Pump, Endocytosis, Exocytosis

• Throwing a ball, Playing tennis, driving a car

Cells sometimes use energy to transport materials across the cell membrane.  This is called

• photosynthesis

• osmosis

• cellular respiration

• active transport

Which is an accurate description of the diagram below?

• Na+ and Amino Acids are both transporting passively.

• Na+ and Amino Acids are both transporting actively.

• Na+ is diffusing passively, and Amino Acids are transporting actively.

• Na+ is transporting actively, and Amino Acids are diffusing passively.

Solutes move against the concentration gradient

• Passive Transport

• Active Transport

What might happen if a cell did not have any ATP/energy?

• It would not have enough energy to do active transport

• It's cell membrane would break

• The transport proteins would not be needed.

What is the difference between active and passive transport?

• Active does not need energy and passive uses ATP (energy)

• Active uses ATP (energy) and passive does not need energy

• Active stores transport proteins and passive releases 

• Active uses hormones and passive does not 

Protein pumps embedded in the cell membrane, such as the sodium potassium pump, are considered active transport because they require:

• O2

• RNA

• ATP

• ADP

Two types of cell transport

• Inner and Outer

• Animal and Plant

• Passive and Active

• Simple and Facilitated

Water can move across the cell membrane through the phospholipid bilayer, and also through protein channels called ____________________.

• porifera

• osmoporins

• aquaporins

• operculum

Endocytosis and exocytosis are examples of:

• passive transport

• active transport

• simple diffusion

• facilitated diffusion
