How do you sabotage a protein? Irreversible egg protein denaturation caused by high temperature (while cooking it). __________ _____! • Alteration of a protein shape through some form of external stress Example, by applying heat, acidic or alkaline environment Denatured protein can’t carry out its cellular function .

Organic Molecules – Nucleic Acids Nucleic acids (both RNA and DNA) are macromolecules; polymers made up of monomers called _____________. Nucleic acids deoxy ribo nucleic acid (DNA) and ribo nucleic acid (RNA) = genetic material of cells. Names derived from type of sugar contained within molecules = ribose Nucleotides Each monomer of nucleic acid is a nucleotide and consists of 3 portions: - a _________ - one or more _____________________ - one of five cyclic ________________________ +adenine, guanine (double-ringed purines) + cytosine, thiamine or uracil (single-ringed pyrimidines) Image: Nucleotide Structure , Wikipedia From the Virtual Microbiology Classroom on ScienceProfOnline.com

Organic Molecules – Nucleic Acids Nucleic Acid Structure Nucleotides linked by covalent bonds between _________ of one nucleotide and ______________ of next (sugar-phosphate backbone). Nitrogenous ______ extending from it like teeth of a comb. From the Virtual Microbiology Classroom on ScienceProfOnline.com

Nucleic Acids - DNA DNA is a double stranded molecule, analogous to a ladder. The “ladder” = • two deoxyribose-phosphate chains form the side rails • base pairs, linked by hydrogen bonds, form the “ rungs” . Purine Bases (double ring) Adenine & Guanine Pyrimidine Bases (single ring) Cytosine & Thymine Base Pairs (purine always pairs with pyrimidine): Adenine + Thymine Cytosine + Guanine ______________ attract the bases from one strand to the bases on the other strand and also twist the phosphate-sugar backbones into a helix.

ATP Production and Energy Storage Q: This molecule has a sugar, a base and three phosphate groups. What kind of monomer is it? Adenosine 5'-triphosphate Multifunctional "molecular currency" of intracellular energy transfer. Organisms release energy from nutrients; can be concentrated and stored in high-energy phosphate bonds of ATP. Transports chemical energy within cells for metabolism.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
