What is the primary function of the citric acid cycle in metabolism?

a. to break down food molecules into smaller components so they can be absorbed by the blood

b. to synthesize atp from the energy produced in the hydrolysis of citric acid

c. to provide the enzymes necessary for the hydrolysis of carbohydrates, fats, and proteins

d. to convert acetyl groups to co2 molecules, and provide reduced coenzymes for electron transport and synthesis of atp

e. to join two-carbon acetyl groups in a cyclic series of reactions to form glucose, which can then be used for energy

The atomic radius of sodium is 186 pm and of chlorine is 100 pm. the ionic radius for na+ is 102 pm and for cl– is 181 pm. in going from na to cl in period 3, why does the atomic radius decrease while the ionic radius increases? a. the inner electrons in the sodium cation shield its valence electrons more effectively than the inner electrons in the chloride anion do. b. the inner electrons shield the valence electrons more effectively in the chlorine atom than in the chloride anion. c. the outermost electrons in chloride experience a smaller effective nuclear charge than those in the sodium cation do. d. the outermost electrons in chloride experience a larger effective nuclear charge than those in the sodium cation do. e. monatomic ions are bigger than the atoms from which they are formed.

Calculate: select the worksheet tab. this tab you calculate the analyte concentration.  fill in the first set of boxes ("moles h2so4" and "moles naoh") based on the coefficients in the balanced equation. (if there is no coefficient, the value is 1.)  record the appropriate volumes in the "ml naoh" and "ml h2so4" boxes.  record the concentration of the titrant in the m naoh box. click calculate. what is the concentration listed
