Cell membrane
What is osmosis?
The diffusion of water across a selectively permeable membrane
Cytoplasm
Where are electrons located?
The electron cloud
What is the chemical formula for water?
H2O
In simple terms, what is ATP?
Energy
Which type of transport requires energy from the cell?
Active transport
Where is the DNA stored in the cell?
Nucleus
What will an atom do if it is not stable?
It will bond with another atom
What type of bond does the hydrogen in Water have?
Hydrogen bond
How do cells make energy?
With the mitochondria (and in plant cells, chloroplast)
What are three molecules present in the cell membrane?
Proteins, carbohydrates, and enzymes
What does the mitochondria do?
Makes ATP for the cell (I’ll also accept “mitochondria is the powerhouse of the cell”)
What is the uneven sharing of electrons in a covalent bond called?
Polar covalent bond
What is it called when water sticks to itself?
Cohesion
What is the molecule called when it loses a phosphate?
ADP
What are three functions of the cell membrane?
Aloes some molecules to pass through but not others, provides structure for the cell, protects the cell from the outside world
What is the space inside of the ER called?
Lumin
What kind of bond does an atom give up/gain an electron?
Ionic bond
What is it called when water sticks to other things?
Adhesion
Why does the cell membrane form a bilayer?
The hydrophilic heads of the phospholipids face outwards and the hydrophobic tails of the phospholipids face inward towards each other, creating a bilayer.
What are the functions of the cytoskeleton?
Provide support and structure for the cell, hold organelles in place, help cells move and divide.
Name the full electron number for the first 4 shells
2, 8, 16, 32
What is the property of water that prevents it from having sudden heat changes?
High specific heat
What does ATP stand for?
Adenosine Triphosphate
