40 What causes the tertiary level of structure of a protein? Lipids and Proteins

40 *interactions amongst the R groups- can be either a disulfide bridge, hydrogen bond, or weak ionic bond *3D structure can either be globular or fibrous

50 *What level of structure does hemoglobin have? Describe it. Lipids and Proteins

50 *quaternary- multiple polypeptide chains interacting

10 Proteins and Nucleic Acids What determines the primary structure of a protein?

10 Proteins and Nucleic Acids Genes on DNA

20 Proteins and Nucleic Acids What bonds cause the secondary structure of a protein?

20 Proteins and Nucleic Acids Hydrogen bonds.

30 Proteins and Nucleic Acids What are the monomers of nucleic acids?

30 Proteins and Nucleic Acids Nucleotides (Consist of nitrogen base, sugar, and phosphate)

40 Proteins and Nucleic Acids Nucleic acids have a 3D helical structure. What makes up the backbone of a nucleic acid? The middle?

40 Proteins and Nucleic Acids *backbone- sugar and phosphate held by covalent bonds *middle- nitrogen bases held by hydrogen bonds

50 Proteins and Nucleic Acids What is the function of an enzyme?

50 Proteins and Nucleic Acids Enzymes speed up chemical reactions by lowering the activation energy of the reaction. *they are neither the reactants nor products in a chemical reaction (they are not used up!)

10 My name is Bond, Ionic Bond; Taken, not shared! Cells

10 Population Growth From: Mariano Cecowski Q: if both a bear in Yosemite and one in Alaska fall into the water which one disolves faster? A: The one in Alaska because it is HIJKLMNO

10 Population Growth Alimentary: What Sherlock Holmes said to Dr. Watson. Urinate: What a nurse would say if a patient asked her what room he's in. Urine - The opposite of "You're out!" Benign: What we want when we are eight. Intestine - Currently taking an exam CARDIOLOGY: advanced study of poker playing TERMINAL ILLNESS: getting sick at the airport
