Cell Transport

The movement of molecules across a membrane from high concentration to low concentration is called:

• Osmosis
• Diffusion
• Endocytosis
• Active Transport

The most modern version of the cell membrane model was developed by:

• Singer & Nicolson
• Davson & Danielli
• Watson & Crick
• Banting & Best

The relationship that governs diffusion rate across a membrane is called:

• Fick's Law
• Bernouli's Principle
• Xeno's Paradox
• The Spaghetti Conundrum

The molecule responsible for increasing the fluidity of the membrane are:

• Glycolipids
• Glycoproteins
• Cholesterols
• Aquaporins

The molecule responsible for allowing water to flow across the membrane is:

• Glycolipids
• Glycoproteins
• Aquaporins
• Cholesterol

The molecule below that will not easily enter the cell by simple diffusion is:

• CO₂
• O₂
• Water
• Methane

Active Transport typically uses ______ to transport materials across the cell membrane.

• ATP
• Glucose
• Na+
• K+
