Hydrogen bond Weak bond interaction Between two molecules amino group Consists of hydrogen and nitrogen atoms (-NH3+) macromolecules A giant molecule in a living organism formed by the joining of smaller molecules: a protein, carbohydrate, or nucleic acid. polymer a long molecule consisting of many similar or identical building blocks linked by covalent bonds Amino acid Amino group + Carboxylic acid + R group = Amino acid carboxyl group A -COOH group, found in organic acids. Coo-, ...

Describe the central dogma of life - Replication> Dna> Transcription> RNA> Translation> Protein label both strands of DNA whether they are coding or non-coding, and template or non-template - point mutation - gene mutation in which a single base pair in DNA has been changed silent mutation - A mutation that changes a single nucleotide, but does not change the amino acid coded for missense mutation - A base-pair substitution that results in a codon that codes for a ...

1. During gluconeogenesis, how many ATP molecules are consumed for each glucose molecule produced? - 6 2. Which molecule signals the liver to release glucose by breaking down glycogen? - Glucagon 3. Which molecule is regenerated with the production of lactate during anaerobic metabolism? - NAD+ 4. During aerobic metabolism, acetyl-CoA is produced from which molecule? - Pyruvate 5.

Bohr effect - a decrease in the amount of oxygen associated with hemoglobin and other respiratory compounds in response to a lowered blood pH resulting from an increased concentration of carbon dioxide in the blood. Cooperativity - Structural communication between various subunits of hemoglobin, a result of its quaternary structure. Deoxyhemoglobin - The form of hemoglobin without oxygen. Oxyhemoglobin - Combination of hemoglobin with oxygen

Activation Energy Energy required to start a chemical reaction. Amino acid Amino group + Carboxylic acid + R group = Amino acid Catalyst Speed up chemical reactions but remain unchanged by the reaction. Chaperones Molecules that help fold a newly made polypeptide. Competitive inhibitor Compete with substrates for binding sites. (Little blockers) Denaturation Process of ruining the functional structure of a molecule. It will no longer be able to carryout it's intended function. Dis...

1. Activation Energy - The energy required to start a chemical reaction. 2. Amino acid - An amino acid is a small molecule containing an amino group and a carboxylic acid group as well as a side chain of variable structure, called an R group 3. Catalyst - substances that speed up chemical reactions and remain unchanged by the reaction they facilitate 4. Chaperones - Helper molecules that assist the folding of a newly made polypeptide. 5. Competitive inhibitor - A molecule which competes ...

DNA - A complex molecule containing the genetic information that makes up the chromosomes. RNA - A single-stranded nucleic acid that passes along genetic messages Central Dogma - DNA->transcription->RNA->translation->protein Bases of DNA - Adenine, Guanine, Cytosine, Thymine Bases of RNA - Adenine, Guanine, Cytosine, Uracil Nucleotide - A building block of DNA, consisting of a five-carbon sugar covalently bonded to a nitrogenous base and a phosphate group. Nucleic Aci...
