Principles Cell Transport

Where are muscle receptors located?

• Around the mitochondria

• On the cell/plasma membrane

• On the cell wall

• In the nucleus

What is the difference between passive and active transport?

• Active transport uses vesicles, passive transport uses pumps

• Active transport is the only one that uses transport proteins

• Active transport requires energy, passive transport does not

• Passive transport is the only one that uses transport proteins

This is an example of...

• Osmosis

• Diffusion

• Exocytosis

• Endocytosis

How are ions moved AGAINST a concentration gradient?

• passive transport by diffusion

• active transport by endocytosis

• passive transport by osmosis

• active transport by proteins/pumps

Cells use ______ to take in large molecules or other cells

• active transport by endocytosis

• passive transport by diffusion

• active transport by transport proteins

• passive transport by osmosis

What is TRUE about passive transport?

• Transport proteins are sometimes used during passive transport

• Molecules move up a concentration gradient from low to high

• Endocytosis and Exocytosis

• Energy is needed

What form of passive transport uses transport proteins?

• Osmosis

• Diffusion

• Facilitated Diffusion

• Protein pumps

Which is an example of active transport?

• Diffusion

Which statement is TRUE about diffusion?

• Movement from high to low based on random motion

• Movement from high to low based on energy

• Movement from low to high based on random movement

• Movement from low to high based on energy

Diffusion stops when the system reaches ___________
