Chemistry Basics
The most abundant element in the human body.
Oxygen
This is water's ability to dissolve many substances.
The Universal Solvent Property
The organelle that synthesizes proteins.
Ribosomes
Movement of molecules from high concentration to low concentration.
Diffusion
These nucleic acids that are larger double ring structures.
Purines
The outermost electron shell.
Valence Shell
Water sticking to itself.
Adhesion
The organelle known as the powerhouse of the cell.
Mitochondria
Diffusion of water across a semipermeable membrane.
Osmosis
What nucleic acid binds with Adenine in DNA?
A molecule composed of two or more different elements.
A Compound

7
The organelle that modifies and packages proteins
Golgi Apparatus
Transport requiring no ATP and moving substances down their concentration gradient.
Passive Transport
_________copies a specific gene's DNA into messenger RNA (mRNA)
Transcription
A bond formed when atoms share electrons
Covalent Bond
Weak acids and bases that resist changes in pH.
Buffers
Organelles that digest waste and pathogens.
Lysosomes
Transport using membrane proteins but no ATP.
Facilitated Diffusion
A set of three nucleotides are known as?
Codon
A bond formed when electrons are transferred between atoms.
True or False: The pH of blood is 3.5-6.8 making it a strong acid.
False (The normal pH of human blood is tightly regulated between 7.35 and 7.45. This makes blood naturally slightly basic or alkaline)
The organelle that stores DNA and controls cellular activities.
Nucleus
Transport requiring ATP to move substances against a concentration gradient.
Active Transport
Nucleotide Structures include three main parts. What are they?
Phosphate Group + 5 Carbon Sugar + Nitrogenous Base
