Anatomy & Physiology Chapter 2 Crossword

Down:
1) Fail to dissociate completely, help to balance the pH2) Accounts of water takes up 2/3 of body water. A Solution is a uniform mixture of two or more substances. It consists of a solvent is which atoms, ions, or molecules of another substance, called a solute, are individually 5) Messenger RNA (mRNA), Transfer RNA (tRNA), Ribosomal RNA (rRNA)7) The concentration of hydrogen ions (H+) in a solution. A balance of H+ and OH- pure water=7.0 8) Most body chemistry occurs in water 9) Are large organic molecules, found in the nucleus which store and process information at the molecular level11) Use more energy than they produce 12) Adding a phosphate group to ADP with a high-energy bond to form the high- energy compound ATP13) In cells, cannot start without help. Activation energy is the amount of energy needed to get a reaction started. Enzymes are protein catalysts that lower the activation energy of reactions 14) Controls intermediate steps in protein synthesis 15) Sometimes ribonucleic can bind to itself but is usually a single strand 16) Water's ability to dissolve a solute in a solvent to make a solution21) A solute that removes hydrogen ions from a solution, proton acceptor, strong bases dissociate completely in solution |
Across:
3) Essential molecules obtained from food 4) An ion or molecule that binds to an enzyme before substrates can bind6) Water's ability to absorb and retain heat 10) The enzyme that catalyzes the conversion of ATP to ADP17) Produce more energy than they use18) Molecules based on carbon and hydrogen, carbohydrates, proteins, lipids and nucleic acids 19) High H+ concentration, Low OH- concentration 20) Molecules made or broken down in the body 22) Solutes that dissociate into cations and anions other that hydrogen ions and hydroxide ions 23) Determines inherited characteristics, directs protein synthesis, controls enzyme production, controls metabolism 24) A solute that adds hydrogen ions to a solution, Proton donor, Strong acids dissociate completely in solution 25) A double stranded, and the bases form hydrogen bonds to the deoxyribonucleic 26) Low H+ concentration, High OH- concentration 27) To moisten and reduce friction 28) Are the building blocks of DNA and RNA. Have three molecular parts- A pentose sugar sugar (deoxyribose or ribose), Phosphate group, Nitrogenous base ( A,G,T,C, or U)29) Nonprotein organic cofactors (vitamins) 30) Molecules not based on carbon and hydrogen, Carbon dioxide oxygen water, and inorganic acids, bases and salts |
