Down:
1) Essential molecules obtained from food 2) Water's ability to absorb and retain heat 3) A solute that removes hydrogen ions from a solution, proton acceptor, strong bases dissociate completely in solution 5) Low H+ concentration, High OH- concentration 8) A solute that adds hydrogen ions to a solution, Proton donor, Strong acids dissociate completely in solution 10) Fail to dissociate completely, help to balance the pH12) Use more energy than they produce 16) Sometimes ribonucleic can bind to itself but is usually a single strand 17) To moisten and reduce friction 19) An ion or molecule that binds to an enzyme before substrates can bind20) Water's ability to dissolve a solute in a solvent to make a solution |
Across:
4) Controls intermediate steps in protein synthesis 6) Produce more energy than they use7) The concentration of hydrogen ions (H+) in a solution. A balance of H+ and OH- pure water=7.0 9) Adding a phosphate group to ADP with a high-energy bond to form the high- energy compound ATP11) The enzyme that catalyzes the conversion of ATP to ADP13) 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)14) Molecules not based on carbon and hydrogen, Carbon dioxide oxygen water, and inorganic acids, bases and salts 15) Messenger RNA (mRNA), Transfer RNA (tRNA), Ribosomal RNA (rRNA)18) Are large organic molecules, found in the nucleus which store and process information at the molecular level21) High H+ concentration, Low OH- concentration 22) Most body chemistry occurs in water 23) Solutes that dissociate into cations and anions other that hydrogen ions and hydroxide ions 24) 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 25) Determines inherited characteristics, directs protein synthesis, controls enzyme production, controls metabolism 26) Molecules made or broken down in the body 27) A double stranded, and the bases form hydrogen bonds to the deoxyribonucleic 28) Nonprotein organic cofactors (vitamins) 29) Molecules based on carbon and hydrogen, carbohydrates, proteins, lipids and nucleic acids 30) 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 |
