200

Organic molecules are synthesized with this process.

What is dehydration synthesis?

200

Cell membranes are primarily made up of 2 layers of this molecule.

What are phospholipids?

200

This membrane protein forms a "hallway" that regulates the passage of specific hydrophilic molecules (ex: ions) into and outside of the cell.

What are transport proteins?

300

What is revise the hypothesis?
300
The most common, and strongest, chemical bond found in bio-molecules.
What are covalent bonds?
300
This biomolecule class is made up of monomers that are polar; rich in C, H, and O atoms; and are used for energy or for structural purposes.
What are carbohydrates?
300

This structure allows cells to move, divide, keep shape, and move organelles.

What is the cytoskeleton?

300

The movement of molecules from areas of high concentration to low concentration.

What is diffusion?

This type of chemical bond forms between polar molecules.
What are hydrogen bonds?
400
This biomolecule class can exist as both hydrophilic and hydrophobic.
What are lipids (phospholipids to be exact?)
400

This organelle is responsible for making proteins by translating RNA.

What are ribosomes?
