Nucleotides
What are the monomers in proteins?
Amino acids
What are the monomers in proteins?
Amino acids
What is a peptide bond?
Bond that holds 2 amino acids together
What are the Levels of structure in Amino acids?
- Primary structure: sequence of amino acids
- Secondary structure: Alpha helix or beta sheet formed by hydrogen bonding
- Tertiary structure: caused by R group interactions
- Quaternary Structure: protein SO complex it ends up somewhere else
5 characteristics of Enzymes ( proteins)
- Proteins
- Highly specific
- Not consumed ( do same reaction over again)
- Lower activation energy
- Binding/ active site
What are enzymes
Biologic catalyst ( make reaction occur faster)
What are enzymes
Biologic catalyst ( make reaction occur faster)

Element that changes # of neutrons
Electrolyte
Ion important in living solutions
Hydrophilic
Substances that like Water
Hydrophobic
Substances that do not like water
What is Cell Theory
If it’s alive, it’s made of at least one cell
What are the five organelles:
- Nucleus
- Ribosome
- Mitochondria
- Plasma Membrane
- Cytoplasm
What does the Nucleus do?
Home for DNA

Protein synthesis ( makes proteins)
What does Mitochondria do?
Powerhouse of cell,
ATP synthesis
Energy
What does plasma membrane do?
Skin of cell
What does the Cytoplasm do?
Watery juice of cell
What are the 3 cell appendages:
- Microvilli- increase surface area of cell membrane
- Flagella- give cell ability to move on its own
- Cilia- moves things away from cell in one direction
What are the 5 types of Membrane transport?
- Filtration- movement of Fluid
- Simple diffusion: solute moving from higher to lower concentration
- Osmosis- water moving from higher to lower concentration
- Facilitated diffusion: special doors for glucose to go through
- Active transport: using ATP to get substance through membrane
Hypertonic

What is the process of transcription?
Replication: Process of using DNA to make more DNA ( mitosis/ meiosis)
Transcription/ translation: use DNA to make mRNA, then to make protein, protein synthesis
Process of replication:
