What is biology?
These types of bonds connect two hydrogen atoms to one oxygen atom in a single water molecule.
What are covalent bonds?
This Macromolecule is responsible for long term energy storage and is the main component of our cell membranes.
What are lipids?
"All living things are made of cells" is the first principle of this important theory
What is cell theory?
This is the phospholipid bilayer that allows certain molecules to enter and exit the cell.
What is the cell membrane?
With Oxygen; In the presence of oxygen
A_ _ _ _ _ _
What is aerobic?
This property of water contributes to most of its unique qualities. It is simply a difference in charges between two sides of the molecule.
What is polar/polarity?
This macromolecule encodes our genetic and hereditary information
What are nucleic acids?
This is the most primitive type of cell. It has a nucleoid and no membrane bound organelles.
What are prokaryotes?
This type of transport can occur in the cell without expending any energy.
What is passive transport?
The process of making or building something
S_ _ _ _ _ _ _ _ _
What is synthesize?
These are weak bonds that form between multiple water molecules.
What are hydrogen bonds?
What macromolecule monomer is pictured next to letter A
Carbohydrate
These are known as "true cells". They contain their DNA in a nucleus and have membrane-bound organelles.
What are Eukaryotes?
This type of transport requires cells to use energy to move materials against their concentration gradient (low to high concentration)
What is active transport?
Water fearing
H_ _ _ _ _ _ _ _ _ _
What is hydrophobic?
This property is described as waters ability to stick to itself. This causes water to form droplets.
What is cohesion?
What macromolecule monomer is pictured next to letter B
Protein
This organelle performs cellular respiration and generates ATP.
What are Mitochondria?
This term describes the movement of water across a membrane. In this process water goes from an area of high water concentration to an area of low water concentration.
What is osmosis?
cells take in particles by engulfing them- cell membrane pinches in to form a vesicle
E_ _ _ _ _ _ _ _ _ _
What is endocytosis?
This property of water allows it to float as a solid.
What is "water is less dense as a solid"?
What is "water expands as it freezes"?
This type of protein works as a catalyst for cellular reactions. It works by lower the activation energy needed for a reaction to occur
What is an enzyme?
These are the protein builders in our cells. Many are attached to Rough ER, giving it it's bumpy appearance
What are ribosomes?
A cell has an internal concentration of 0.5M of salt. It is placed in a solution with a salt concentration of 2.0 M. Which way would you expect water to move across the cell membrane?
Out of the Cell
