Transport proteins: active transport or large molecules

38
Q

When a lysosomes collides with a food vacuole what happens

A

They would digest the food in the vacuole

39
Q

What packages materials for removal from the cell

What are found in every living cell

A

Cell membrane and ribosomes

47
Q

What factors increase the Rate of diffusion

A

Distance, concentration of substance, and weight of molecules

48
Q

Why is surface area to volume ratio important for cells

A

The ratio must remain small for the transport of molecules
