Unit 03/04: Cell Transport and Energy Conversions

Active / passive transport requires energy in the form of ATP.

• Active

• Passive

Endocytosis / exocytosis is when vesicles release material from the cell.

• Endocytosis

• Exocytosis

Answer explanation

Exocytosis is when vesicles release, or removing, material OUT of the cell.

All of the following apply to the cell membrane EXCEPT -

• Allows things to enter/leave the cell

• Are present in ALL cells

• Contains the DNA in eukaryotes

• Helps to maintain balance in the cell

Answer explanation

Eukaryotic DNA is in the nucleus
