• They facilitate the movement of molecules

• They store energy

What is the main function of transport proteins?

• To synthesize proteins

• To move substances against the concentration gradient

• To store energy

• To break down molecules

What is the primary role of ATP in cellular processes?

• To store genetic information

• To provide structural support

• To supply energy

What does the term "phagocytosis" literally mean?

• Cell division

• Cell movement

What is exocytosis?

• The release of substances into a cell by the fusion of a vesicle with the membrane

• The release of substances out of a cell by the fusion of a vesicle with the membrane

• The absorption of substances into a cell by the fusion of a vesicle with the membrane

• The absorption of substances out of a cell by the fusion of a vesicle with the membrane

The process of taking molecules into the cells by engulfing them in the cell membrane is called

• exocytosis

• endocytosis

• diffusion

• osmosis

The two main type of transport proteins are shaped like

• a tunnel and claw

• a beach ball and Gumby
