Cell Transport Review

• Which cell transport passively allows molecules to go across a cell membrane such as between the cells of the lungs and capillaries?

• Diffusion

• Which cell transport engulfs large particles as that in the immune system (phagocytes)?

• Endocytosis

• Which cell transport moves ions in different numbers across the cells membranes set up an electrical potential?

• Sodium Potassium Pump

• What is the purpose of the protein in facilitated diffusion?

• It helps the molecules such as glucose go with the concentration gradient across the membrane.

• What is osmosis?

• The diffusion of water across the cell membrane with the concentration gradient.

• What happens to cells in isotonic, hypertonic and hypotonic solutions?

• Isotonic=Water remains at equilibrium on both sides

• Hypertonic=Water is driven out the cell.

• Hypotonic=Water is driven into the cell.

• What is the definition of active transport?

• The movement of molecules against a concentration gradient.

• What system would benefit the greatest from cell undergoing exocytosis?

• The endocrine system. They give off tremendous amounts of hormones.

• Which systems rely on osmosis?

• The urinary system.

Which system produces vitamin D when exposed to the sun?

• Integumentary

• Which system provides support and protection?

• Skeletal

• Which system produces hormones to allow for proper growth, reproduction and response?

• Endocrine system

• Which system moves waste, carbon dioxide, oxygen and food to and from all the cells?

• Circulatory system

• Which system is responsible for the secondary sex characteristics?

Reproductive system

• Which system contains nodes, vessels, the spleen, adenoids, and tonsils to help fight disease?

• The lymphatic/Immune system

• Which system breaks down food into small enough molecules for the body to absorb them?

• The digestive system

• Which system exchanges oxygen for carbon dioxide and vice versa?

• Respiratory

• Which system is capable of producing heat?

• muscular
