Active and Passive Transport 2021

What is the difference between active and passive transport?

• Active does not need energy and passive uses ATP (energy)
• Active uses ATP (energy) and passive does not need energy
• Active stores transport proteins and passive releases 
• Active uses hormones and passive does not 

What does semi-permeable mean?

• Only some things can move through membrane
• Nothing can move through membrane
• Only oxygen can move through membrane
• Membrane connot be moved through

What are three types of passive transport

• Transport proteins, Endocytosis, Exocytosis
• None of the ones listed
• Osmosis, Diffusion, Facilitated diffusion 
• Touchdown, interception, football

What are 3 types of active transport?

• Riding a bike, Running through the mountains, walking on the beach
• Osmosis, Diffusion, Facilitated Diffusion
• Phagocytosis, Endocytosis, Exocytosis
• Throwing a ball, Playing tennis, driving a car

What is equilibrium?

• When concentrations cannot be balanced between two substances 
• When concentrations are balanced between two substances 
• Making the energy in the top half of your body equal the the energy in the bottom half
• Concentrations do not exist 

what does the cell membrane consist of?

• Lipid Bi Layer
• Protein Bi Layer
• Lipid Tri Layer
• protein and lipids layers

Permeable means

• things can pass through
• the concentration levels are different
• it is permanent
• things are stuck

Passive transport requires no

• concentration gradients
• osmosis
• motion
• energy

What is diffusion?

• when molecules move 
• when molecules move from a high concentration to a low.
• no movement 
• molecules move everywhere

What is the definition of  Selective Permeability?

• The movement of materials across the cell membrane that requires NO ENERGY from the cell.
  
• The movement of materials through (or across) the cell membrane
  
• The ability of the cell membrane to allow some things to pass through while preventing other things from passing through.
• The movement of molecules from an area of high concentration (where the molecules are more crowded together) to a area of low concentration (where molecules are more spread apart)
