Diffusion Quiz 1 Flashcards
How oxygen gets to cells
Atmosphere to lungs to bloodstream to cells
How low temp effects diffusion rate
Particles have less kinetic energy
They move slower, slower rate of diffusion
How high temp effects diffusion rate
Particles will have more kinetic energy
They move faster and faster rate of diffusion
What is surface area
Cell membrane
What is volume
Cytoplasm
How more volume and less surface area effects diffusion rate
Less surface area for oxygen to cross and more cytoplasm for oxygen to travel
Lower diffusion rate
How less volume and more surface area effects diffusion rate
More surface for oxygen to cross and less cytoplasm for oxygen to travel
Faster rate of diffusion
How low amounts of particles on one side of membrane effect diffusion rate
Low concentration of oxygen per volume
Less diffusion
How lots of particles on one side of membrane effect diffusion rate
High concentration of oxygen per volume
More diffusion
Why do we need to breathe
To get oxygen in our bloodstream and cells
Why do we need to eat
To get glucose in our bloodstream and cells
Why do we need oxygen and glucose
They are reactants for cellular respiration
What is cellular respiration
Process that makes stored atp
What is atp used for
storing and releasing energy
What is atp
Energy for the cell
How is atp made
From adp
How atp releases
Breaking bond between 2nd and 3rd phosphates
Why o2 is best molecule to make atp
Attracts electrons, force and guide, forms stable water molecules
What is aerobic respiration
Normal cell respiration when oxygen is present
What is anaerobic respiration
Makes atp from only glucose, used when no oxyhen
Why human can only survive 4-6 minutes without o2
Brain only lasts 4 minutes
What is diffusion
Movement of particles across a space
How particles tend to move
High concentration to low concentration
What are neurons
Cells that send messages across body
