Carriers & Endo/Exocytosis

What types of protein carry out facilitated transport?

Carrier & Channel Proteins

What type of proteins carry out active transport?

Carrier proteins only

What can pass through the cell membrane using facilitated transport?

• Sugars

• Amino Acids

What can pass through the cell membrane using active transport?

• sugars

• amino acids

• ions

What type of transport uses energy and whats its associated protein

• Active Transport

• Carrier Protein

What type of transport goes with or against the concentration gradient?

• With: Carrier, Channel

• Against: Carrier

What are 5 examples of the functions of Active Transport?

• Nerve cells

• Muscle cells

• Kidney tubule cells

• Thyroid gland

• Cystic Fibrosis

What does active transport do for the thyroid gland?

• moves I⁺ from blood → thyroid

• I⁺ low in blood, high in thyroid

What do kidney tubule cells do?

Use active transport to take Na⁺ out of urine

How do nerve and muscle cells use active transport?

• release Na⁺

• Absorb K⁺

What is Cystic Fibrosis and how does it happen?

• genetic disease

• blockage of Cl^- transport channels

What is transported through endocytosis and exocytosis?

• macromolecules

• cells

• subcellular material

What are the two types of Endocytosis?

• Phagocytosis

• Pinocytosis

Phagocytosis: Size of particles involved and examples

• large particles

• white blood cells

• amoeba

Pinocytosis: Size of particles involved and examples

• small particles

• intestine cells

Give two examples of exocytosis

• waste from amoeba

• cell products from golgi apparatus

• this is excretion/secretion
